What's up guys? I'm Andy from 1A Auto. In this video, I'm going to show you how to replace the rear lower control arm on this 2001 BMW 325XI. If you need this part or other parts for your vehicle, click the link in the description and head over to 1AAuto.com

I'm going to loosen up these lug bolts. I'm going to use a 17 millimeter socket and a breaker bar. Now I'm going to raise and support the vehicle. We're using a two post lift. If you're doing this at your house, you can use a jack and jack stands.

Now I'm going to take the 17 millimeter socket and an extension just to take the lug bolts out. Now when I go to take the last one out, I am going to hold the wheel so that the wheel doesn't fall. Take that one out, set it aside and grab the wheel and shake it off.

I want to pull this bolt out, this nut and bolt. There is a cam in here that is to adjust the alignment so after you do this repair, you're going to have to go to an alignment shop and have your alignment performed. Now I will take some rust penetrant, just get it on there. It's really rusty so spray it down, let it soak for a little bit.

Take an 18 millimeter wrench, put it on the backside of the bolt then I'm going to take a 18 millimeter socket, just going to, because this is rusty, just take a hammer, tap it on there real good. Then I can either use a breaker bar or I'm going to use this air gun. Loosen this up. We actually sell this air gun at 1AAuto.com. Make sure you're in the loosen side. Because that nut was really rusty, I couldn't the 18 millimeter socket to work, it was just spinning so I'm using a 17 millimeter socket, I'm just going to hammer it on there, try again. There we go. Loosened it up. Take it off by hand. And there you go.

Now I can tap the bolt out. You don't want to hit it too hard, you don't want to mushroom it. Just tap it a little bit. I'm going to use a punch and drive this through. We actually sell a punch set with these punches at 1AAuto.com. Take that washer off, we're going to have to reuse that. You can kind of judge when you put the new arm on, kind of how the washer was. If it was to the side or to the other side, put it on the same way.

Just be careful when you punch this bolt out. Punch that out just like that. Just going to push the lower knuckle and slide that out. The knuckle's just going to slide in a little bit. Just be careful. You don't want this arm to hit you or anything. Next, we want to pull this bolt out right here. On some vehicles you may have to remove the axle to get the bolt completely out. I'm going to try taking the bolt out first but my assumption is, I'm going to have to pull that axle out. I'm going to use an 18 millimeter socket and breaker bar and break it loose.

Now I'll use a 18 millimeter ratchet wrench and try to get it out. Just spraying a little rust penetrant on here, make it come out a little easier. That's completely loose. There is this little thing right here that's like the little nut. It's nice, it has this little ear that prevents it from spinning so you don't have to put a wrench on that side. Just slide the bolt out. Let's see and it just made it out so I don't have to pull the axle which is nice. But, if you have trouble and you can't get the bolt out, pull the axle out.

With a pry bar or a screwdriver, take this little plastic cover off right here. Just like that. I'm just going to spread this control arm apart a little bit, slide it out, just like that.

Here's the old part, here's the new part of 1AAuto.com. It's got the same shape. It's got the same mounting locations. It's got the same bushing on the other side. Get yours at 1AAuto.com and you can do it yourself.

All right, take the arm, we want to install the arm with the flat part on the top. The bottom part has the curved part just like that. Get that lined up. It's easier to put the bolt in now. Get that in or at least started. Before I completely put that in, I want to put that other piece, this piece in. This lined up. On the backside and just get this started. With that started, we can line this up. We can spread these out a little bit. Just be careful not to spread it too much, you don't want to bend it. Just like that. We can take the pry bar, be careful not to hit your brake line. Line it up. Pull the head out.

All right, now we're going to install this cam bolt. Remember the location of how you took it out then your alignment will be closer. It's still a good idea to go have the alignment adjusted afterwards. Go a repair shop, have that done. We'll slide this in on the backside first. And that's good. Lined up, slide this down and just get that lined up there. Watch your fingers. Be careful. Once you get it kind of lined up, grab a hammer and tap the bolt in while you pry it out. There we go.

Holding the bolt from the backside, I'll just tap it a little bit. Then we'll take this washer, slide this on and with a wrench I can try to position this kind of how it was. My 18 millimeter wrench, just get the nut on. This nut was stuck in the socket. It's an 18 millimeter socket you used for this but this one I'm using a 17 millimeter because it's rusted. Little bit smaller. Take a ratchet, get this in position. On our vehicle it was pretty much straight up and down. Make sure that's good on the other side. We'll snug this up. Now before I torque this nut down, I just want to take the load off the suspension. You kind of want to get the suspension in the same position it would be while you're driving down the road. If you have the ability to do that before you torque this nut and same with this bolt over here. If you can do that, would be good. Just be careful.

Now with my 18 millimeter wrench on the backside, 18 millimeter socket on this nut and a torque wrench. We actually sell this torque wrench from 1AAuto.com. I'm going to torque this to 81 foot pounds. That's good. And with the suspension still raised up, I'm going to use my ratchet wrench, tighten this down, then I'll use the torque wrench and torque this to 81 foot pounds as well.

After you're done getting the arm on, just take this plastic piece. It's just a little trim piece and slide this in position. Just locks in place. Lock the top part in first and then just rotate it, get the bottom part in. Now I'm going to take the wheel, slide it in position. Make sure the holes lined up and hold the wheel. I'm going to take my 17 millimeter socket and the lug stud and get one started. And I can grab the other ones. I'm going to use a 17 millimeter socket and a torque wrench and I'm going to torque these lug bolts in a star pattern to 95 foot pounds. Go right around again, just make sure everything's tight. And you're good to go.

What's up guys? I'm Andy from 1A Auto. In this video, I'm going to show you how to replace the driver's side rear lower control arm on this 2001 BMW 325xi. Now the driver's side lower control arm is a lot more difficult than the passenger. There's more steps involved, so if you need this part or other parts for your vehicle, click the link in the description and head over to 1aauto.com. I'm going to take the wheel off. I'm going to use a 17 millimeter socket and this air gun that we sell at 1aauto.com. If you don't have an air gun, what you can do is use a breaker bar and loosen up all of the lug nuts before you raise the vehicle. When I go to take the last lug nut out, I'm just going to support the wheel. Just push on it because these are lug studs, not lug nuts, so there's no studs holding the wheel on after you get them all off.

Slide that out of the way and grab the wheel. Pull it off. I'm just gonna take some rust penetrant. This nut and bolt is pretty rusty. Spray that down and then also up here, spray this one down because we're going to take that one out next. I'm going to use a 18 millimeter socket and I'm just going to hammer it on because this one's pretty rusty. I'm going to use that 18 millimeter wrench on the backside to hold the bolts on. Now this bolt has a cam on it, at least cam washers. That's going to adjust the alignment on this vehicle. So after you are done this job, you're going to want to go to alignment shop and have your alignment performed. So try to keep in mind where the alignment cam is, so when you put the new arm on, it's going to be close. But at least keep in mind you have to go get an alignment.

Now I'll take this gun, loosen this nut up as I hold the wrench. If you don't have a gun, just use a breaker bar. So this nut is a pretty badly rusted and it's starting to strip. So I'm actually going to bang a 17 millimeter socket on there. It's going to be a little tight, but it will fit. So this nut's really tight on there so I'm just going to use a breaker bar, loosen it up. Now that it's loose, I can use the gun. Slide that out, can take that cam washer off of there. Just going to use this punch and punch the bolt out. We sell these punches in a kit from 1aauto.com. Make sure you save that. Then from the backside of the bolt I'll just punch it out.

Alright, to take that bolt off the rest of the way, I'm just going to use a pry bar, make sure I don't hit the brake line. Just slide this out, slide the bolt out. There it is. Need to access the bolt right here and it's pretty tight in there. The exhaust is in my way. The differential might be in my way as well, but for starters, I need to move the exhaust. So I'm going to support the exhaust with a screw jack, and I'm going to take these mounts off just at the rubber part right there, and then there's also one right here. So this one is already a little bit loose. I can just take a pry bar, get in there and pry this out. You can use a little soapy water to help you get it off if you want. Same with this one.

Then I can move the exhaust to the side a little bit and then I can access this bolt a little bit better. So next I want to remove this bolt but I can't because I can't even get the socket in there. You can try to get a wrench in there. Obviously this isn't the right size, but you could try to get a wrench in there and see if you can get that bolt out. But I need to move this differential over a little bit. So I am going to loosen this bolt up. I already removed the hangers for the exhaust and pushed that over a little bit. That helped out. So now I'm going to take a 21 millimeter wrench, stick it on this nut right here, and then I have a 21 millimeter socket and a breaker bar and I'm going to loosen this up.

Right so I have this bolt loose, got that nut loose. I can switch to a ratchet. Before I do that, I want to support the rear differential. I'm just going to use the screw jack and place it underneath there. So I'm going to use a pole jack underneath here. I have a rubber pad. You could use a block of wood or something just so that you don't damage anything. That's good, get that supported, you can take this bolt out. That's loose enough. Just take that nut off, right there. Try to move the differential up and down, slide the bolt out. Now I can just move this differential up a little bit, not too much, and it gives me a little more room in there. I can try to get a socket on there.

So I need to access these two bolts right here. There is this plate in my way. I am going to take this out. There's two nuts on either side right there and there's a couple of little smaller bolts that I have to take off as well. So let's take those out. Let's start by taking this shield out right here. I'm going to take take those two bolts out right there. All right, I'm going to take the shield off. I'm going to take these two bolts out and use a 10 millimeter socket and ratchet. Take that one out and take this one out. Slide that off.

So there's two bolts right here, two bolts right here. I'm going to use a 13 millimeter socket extension and a ratchet. Take these out, cut all those out. Now I want to take these two nuts out. I am going to use a little rust penetrant. These nuts are pretty rusty. Now I'm going to take this nut off and this nut. I'm going to use an 18 millimeter socket and a breaker bar. I'm going to do the same on this side. I'm just going to use a shorter socket so I can get above the exhaust. If you're having trouble with the exhaust, you can pull the exhaust down completely out of your way. But I would rather just try to work around it. It's a little loose. I can switch to a ratchet. All right, now these are loose enough I can take those off. Take this one off. Slide this out of my way.

No, what I am going to do is right now the differential is supported so I was able to take that bracket out. This whole lower sub frame is bolted in, in the back side as well, but I don't want this to fall down anymore. So I'm going to take those nuts and I'm just gonna stick those right here and right here because when I take these bolts out, the sub frame might fall down. So rather than having it go all crazy, I'll just put those back up and just remember I have to take those back off before I put that bracket back on. Now I'm going to take a 18 millimeter socket and a breaker bar. I'm going loosen these bolts up. I'm just going to switch to a ratchet and the same 18 millimeter socket.

So I didn't take these bolts out. I just loosened them up about an inch of clearance right there, which is going to be good. I can just position the rear differential up a little more. With those loose, now I can go up with this and just take a pry bar and just position this out a little bit just like that. So you have more clearance in there. You can pick, take a block of wood or something. Just be careful. Don't pry too much, you don't want to mess up the axles. And then I can get in there with my 18 millimeter socket and breaker bar. Loosen up that bolt. Once that's loosened with the breaker bar, I can switch to a ratchet with an 18 millimeter socket. And then once my ratchet gets a little too tight, then I'm going to use my gear wrench, 18 millimeter. And that's all the way out.

This is basically the nut that goes on the backside. It's not actually a nut, it's just a little cam type thing that the bolt threads into and this prevents it from spinning, so you don't actually have to put a wrench on the backside or anything. So that's good that that's out. So now we're ready to pull the bolt out. Take a pry bar and try to pry it out. And it's almost there. I could still use the ratchet wrench a little bit. Just don't want to get the ratchet wrench stuck.

I am going to use a long pry bar. Get in here and pry so that I can slide the lower control arm down a little bit. Actually before I do that, pull the cover off right here. Slide that out of the way. Now I can pry this out, slide that down like that. Now I should be able to grab this bolt and slide it up and there we go. Got it out. Here's the old part. Here's the new rear lower control arm from 1aauto.com. The length is the same, the bushing is the same, it's got the same shape, has the same tabs for the alignment cam on the back. Get yours at 1aauto.com, you'd be ready to rock and roll.

Now I'm going to slide this in with the curve on the bottom part of the lower control arm. Slide it in right here, slide that in position there, take the bolt, get the bolt lined up. So I do want to put this on the back side. I want to pull the bolt out a little bit and then over here, take this, this is going to slide on the front side and just try and get the bolt threaded on that. That's good. Once that's started, then we can tighten the bolt down. Before I tighten that bolt up, I actually want to put the bolt in for the lower control arm over here. I'm going to take one pry bar right here, I'm gonna take another pry bar right here. Try to get this in position. I'm going to have to push it, push the arm a little bit, and then just try to separate it. Get that to line up. That's lined up and I can take the bolt and the bolt's going to go from the front of the control arm towards the back.

Just try to slide this through. We can put this cam washer on and then the bolt. Now this cam on this side was the opposite of the passenger side. This cam take a 18 millimeter wrench. Just going to twist this. So this cam was in this position when it came off, so we'll tighten that up like that. Just take a 18 millimeter socket and ratchet or a ratchet wrench. Snug this up. Put a 18 millimeter socket and ratchet on the other side. Just make sure this turns pretty good. That's good. Looks good on both sides. Just snug that up for now.

Okay, at this point before I tighten two bolts up before I torque them, I'm gonna take a screw jack or a pole jack and try to get the suspension where it would be if the vehicle was on the ground. You just got to be careful when doing this. Ideal would be if you had some ramps, if you were driving on some ramps and then you could tighten those bolts. But obviously that's not the easiest thing in the world, so I'm just going to move it as close as possible. That way the bushings that are in the arms will last longer versus they won't twist as much. So try to get it as close to right height as possible.

I'm just going to use a ratchet wrench. Tighten this bolt down and then I will torque it with a torque wrench. Now I'm going to use my 18 millimeter socket and this torque wrench. We actually sell this out 1aauto.com. I'm going to torque this bolt to 81 foot-pounds. And right here while the screw jack is still there, I'm going to take a 18 millimeter socket and ratchet on the backside of this cam bolt and torque this nut right here to 81 foot-pounds. Keep in mind putting this cam washer, how it was when it came off, if it was twisted a little bit, and try to get it roughly the same area. That way, when you go to have it aligned, it'll be closer.

Now that those bolts and that nut is torqued, I can loosen this up. Now I can loosen the rear differential, loosen this screw jack down a little bit, pole jack, slide this bolt in back here. I might have to push the differential forward a little. Take a pry bar, push it forward a little bit. Or you could snug up those bolts a little. But we want to get all the bolts in before we torque them down. There we go. Slide that in. Take the nut, install the nut.

From the front side, I'm just going to take a 18 millimeter socket and ratchet. Just snug these up, not too tight. Just snug this one up as well. With those snug, I can remove the screw jack and then I'm going to torque those. Now I'm going to torque these two front bolts with a 18 millimeter socket and a torque wrench to 70 foot-pounds. I'm just going to use a 21 millimeter socket, a ratchet, and a wrench. Put a wrench on the nut and tighten up the bolt. Then I'm going to use a torque wrench and I'm going to torque this to 128 foot-pounds.

All right, now I'm going to take these nuts off that were holding this cradle up. I'm just going to leave the screw jack underneath here just in case anything decides to fall or shift. Take those off and I'll take this bracket, get this bracket lined up. Just like that. Get these nuts started. Now before I tighten those up, I'm going to take these four bolts with my 13 millimeter socket and extension. Just get these all started. Once they're all in, then I'll just snug them up with a ratchet. Then I'll tighten up these nuts. I'll just use a 18 millimeter socket and a breaker bar. Tighten them up. Make sure they're snug.

Take this plate, get it lined back up. Take the two small bolts, get them started, one here and one goes right here. Get those bolts installed. Then take a 10 millimeter socket and ratchet and tighten them down. Snug that up. Now we'll take this cover, slide this in position there. They'll just lock in place. Now we can remove the pole jack. Slide that out of the way. Right, so I'm just going to use the pole jack to help me with the exhaust. Slide this exhaust hanger on in position. Just make sure this one's out of the way as well. We can start this one first. Just going to use a pry bar, pry this on. You could also use a little bit of soapy water. You really don't want to use any type of lubricant. Slide that on there. If you had to take the vacuum line off this rear actuator that actuates the exhaust valve, reattach that. This vehicle, it doesn't have it.

Slide this side on and that's on, so loosen this up. Take the wheel, put the wheel back on, slide it in position and just hold it, hold that on. Just take the lug bolts, get those started. Now I'm going to use a 17 millimeter socket and this torque wrench we sell at 1aauto.com. I'm going to torque these lug bolts to 95 foot-pounds in a star pattern so that it torques the wheel down evenly. I'm just going to go around again, double check.
