Brought to you by 1AAuto.com your source for quality replacement parts and the best service on the internet. Hi, I'm Mike Green. I'm one of the owners of 1A Auto. I want to help you save time and money repairing or maintaining your vehicle. I'm going to use my 20-plus years experience restoring and repairing cars and trucks like this to show you the correct way to install parts from 1AAuto.com. The right parts, installed correctly that's going to save you time and money. Thank you and enjoy the video.

This video is part one of a two-part series, replacing the ball joint in this '97 Expedition. In this video, we basically detail removing the old ball joint. This is the same for all the Expeditions, F150s, Explorers, a whole bunch of the Ford trucks and SUVs from this era.

Here's a list of the tools that we use on the Expedition. If you're doing a vehicle different from the Expedition, some of these sizes may differ. You will need heavy-duty tools. You're not going to want to try this with the 20-piece set Uncle Joe gave you for Christmas. This is heavy work. You'll need jack and jack stands, metric sockets 13-27 mm, standard sockets 1/2 inch to 7/8, you'll need a 35 mm socket, a 12 point 13 mm socket, ratchets extensions and a breaker bar or pipe because you will need to get some leverage on some of those bigger bolts and things, pliers, hammer, a heavy punch, ball joint removal tool, ball joint press, large flat blade screwdriver, and a paint marker or a old can of spray paint. The ball joint removal tool I'd recommend if you're going to be doing a lot of your own work. It's a pretty affordable tool to go out and get. Ball joint press might be something that you want to borrow.

Obviously, you're going to start by removing your cap. If you don't have the benefit of air tools, what you'll want to do is start with your wheel on the ground. With your wheel on the ground, there are probably three things you're going to want to do. Loosen your lug nuts. Then there's a 35 mm bolt in the center that holds the axle into the hub you're going to want to take the cotter pin and the cover off of that and loosen that 35 mm bolt. Also, go underneath and there are seven 13 mm 12 point bolts that hold your axle to your front drive. You'll want to just loosen those seven bolts. Much easier to loosen all these bolts with your tire on the ground held in place if you don't have all the tools that I have access to. You're going to want to loosen up your torsion bar. Your torsion bar is actually your spring. This is what supports the vehicle. I'm just going to take a little silver spray paint ... That way, when I back that bolt out, I'll know where it originally was.

Using an 18 mm socket and a ratchet, I'm going to loosen the torsion bar tension nut, or bolt, and you can basically pull it all the way out and then just turn it back in a few turns. You just want to loosen it up and take as much tension off the torsion bar as you can. You can see as I'm done, you can see where there's no paint on the threads, that that is how far you would want to retighten it. Now we're going to undo our tie rod end here. I'm just going to speed it up here. The cotter pin's very rusty, so first so first I break it with the pliers. Then I use a hammer and punch and just kind of keep working and breaking small pieces off until I can drive it through and out of the tie rod end. Now I'm pounding a 21 mm socket onto that nut because it was quite rusty. I just want to make sure I get a good socket that gets a good grip on it.

I've got a bar on here. Put a piece of pipe on it for some more leverage. Hopefully it comes apart. Just fast forward here as I switch over to a ratchet and remove the nut the rest of the way. Here I'm going to put a tie rod, it's a tie rod and ball joint tool, but obviously I'm using it to do a tie rod right now. By using this tool, I can assure that I can just reassemble my tie rod. I won't damage the tie rod by removing it this way. Next, I'm going to remove the stabilizer link, so I'm going to spray the top of it with some penetrating oil and let it sit for awhile. These stabilizer links are sometimes difficult to get apart. You can use hand tools. They will come apart. I just chose to use a impact wrench just to make it easier. I have a 9/16 socket on the bottom and a 14 mm socket on the top.

Use a hammer and pound down on that bolt. Then use a punch, see if you can it to go down through the sleeve. I end up actually having to use vice-grips and a wrench. Obviously, you also want to remove the other side so you can move your stabilizer bar around easily. What I'm going to do here, put set of vice-grips onto this shaft, tighter here. Now we're going to remove the half shaft of the CV axle. As I said in the beginning of the video, these are the bolts that if you don't have all the tools that I have, it might be easier to just loosen them while the vehicle's on the ground. You can see I use a big, large crowbar to hold the hub in place while I'm loosening those bolts.

You can see I spin it, loosen one of the bolts, spin it some more, loosen another bolt. If you were actually doing this with your vehicle on the ground, you'd have to probably loosen one or two of the bolts, then roll your car a little bit, put it in park, put the emergency brake on, loosen a couple more, and keep repeating that process.
Once it's unbolted, pull it down and off. I use a pair of pliers and either break off the ends or just straighten out the cotter pin and pull it out. Okay, 35 mm ... As I said in the beginning, if you don't have impact tools and this is easier with the tire on and on the ground, your other option would be to have a helper hold the brakes while you remove it.

What I do is give it one tap and just watch it, see if it moves. Actually, it moves pretty freely. You can pull your stabilizer bar up and out of the way. Pull your axle down towards the front. Then push it, lift it up, push it out. I've got the vehicle support under the frame. Then I've got my jack right under the control arm. You can see there is the bolt for the ball joint, and then there's the jack. I have a piece of the wood on there so I can easily access that ball joint bolt, as well as get a puller on there. Now I can jack it up. You can see, without that torsion bar tightened, the suspension travels here very easily.

Now I'm going to use pliers to break off and remove the cotter pin from the lower bolt. It ends up being kind of a rusty mess, so I actually use a hammer and punch and pretty much just break it away as much as possible so I can get that bolt off. Now a 27 mm socket put it on there, use a little hammer, make sure it goes all the way on. Got a breaker bar on there, actually you're going to take piece of pipe, put it on, give me some extra leverage. It's coming loose. Just one note here: It will help if you take your tie rod and put it back into the steering knuckle and just put the bolt on. That tie rod will hold things in place while you loosen that ball joint nut.

Just speed it up as I change over to my ratchet and take that bolt most of the way off. While my bolt's still on there, take my ball joint removal tool- This just, doing it this way, allows you to break it free without things falling down. Finish removing this bolt. Get your control arm on up. Pull the steering knuckle down and off.
There's a snap ring that holds the ball joint in place. You can use snap ring pliers. Mine was pretty rusty so I used a screwdriver and a hammer to just kind of pry it off and pop it off.

Now you're going to take a ball joint pulling tool, put the collar up on there. With this particular press use a 7/8 socket, put one on top there, and just tighten down the press. Traded my ratchet handle for my breaker bar. I'm going to speed it up here. What I did there was I created a whole lot of pressure by tightening it down. Then I used a hammer, gave it a good whack that kind of broke it free, and then the press just works it the rest of the way out. There's my old ball joint out.
Good a place as any to end it. Check out part two for the reassembly.

Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.

In this video, we're going to show you how to replace the lower ball joint on this 2003 Mercury Mountaineer. We show you on the driver side, but the passenger side is the same procedure. It's the same part and similar process on these Mountaineers from '97 to 2010. The items you'll need for this are a new lower ball joint from 1AAuto.com; 15, 18, 19, 21, 24 and 30mm socket and ratchet; a piece of pipe for some leverage; pliers; snap-ring pliers; a flat-blade screwdriver; hammer; ball joint press; torque wrench; jack and jack stands, and locking pliers, depending on the condition of your sway bar link.

Start off by removing your hub cab and then remove these 19mm lug nuts. If you don't have air-powered tools, you want to loosen them up while the vehicle's on the ground, then jack up the vehicle and support it, and then loosen the lug nuts the rest of the way. Once you've removed those, you'll be able to pull it free.

Now, you want to break off the ends on the Cotter pin right here underneath your wheel knuckle and then you can either hammer it out with a punch or, if the Cotter pin is only sticking out on one side of the castle nut, you can actually just use your 24mm socket and ratchet to break it free. Then, just remove that nut and then put it back on just a few threads.

Remove the nut on the end of the axle and, obviously, if you have air-powered tools it's not a problem. You can have somebody hold the brakes and use a socket and breaker bar if you need to. You want to twist this nut back on until it's flush with the axle and just hammer it until you can see it move. Then come up here and just remove this 18mm nut. With that nut twisted on, again, just a few threads, hammer the wheel knuckle until it drops down. Then, using a 15mm socket and ratchet, you want to remove the nut at the top of your sway bar link. You can hold the bottom with a wrench if it's turning. You can see ours is turning and, in an ideal world, this would just loosen up and you could pull it down, but the top of ours just breaks off.

To help get it out, you want to jack up the other side of the vehicle, and this will lift the sway bar on this side, allowing you to get to the top of sway bar link easier. We'll just spray it with some penetrating oil. Then, using locking pliers, you want to hold onto it while twisting the nut on the bottom of the sway bar link. You'll notice that the plastic will start breaking away and that's fine. You just want to keep repeating the process until all the plastic is gone and you have better access to it. We'll fast-forward as Mike does this. When it gets to this point, you'll be able to remove it and slide it down and out. If it is jammed up, just use a hammer.

Now disconnect your tie rod end, so remove the Cotter pin from the tie rod and I break off the bent over section. I just break it off and then I'm able to pull out the rest of the pin. Then, a 19mm socket, ratchet and a breaker bar loosen it up. You want to take the nut all the way off and then just thread it back on a few threads. Then hit the steering knuckle with a hammer until it pops free. Remove the nut and take the tie rod off and set it aside. If the nut is still on the lower ball joint, hit with a hammer to break it free.

Now support your lower control arm. You can see I have jack stands underneath the frame in the front for both sides. Jack that up with a jack. Here again, make sure the axle is free. I'm not hitting that hard. You don't want to hit your axle too hard because you could damage the CV joints. I'm really just tapping it. Jack it up a little further and now just lift up on the steering knuckle and remove the nut from the lower ball joint. Now remove the nut at the top of the wheel knuckle and pull the upper control arm out of the knuckle.

Take the axle out. Then, you want to take the wheel knuckle and pull it off the stud on the lower ball joints. Just remove that nut the rest of the way. Put it back on there and then just pull the wheel knuckle down and off that stud while pulling your axle out at the same time. It can be a little difficult, but it will eventually go. It's a good idea to just keep it secured to the top of the upper control arm, so just put that nut back on halfway for now.

Using snap-ring pliers, remove the snap ring along the top of the ball joint. Once you get it about halfway, you can just use a flat blade screwdriver and pry it up the rest of the way. With the ball joint press, we've got a cup around the lower part of the ball joint and that there, with a hole through there, so just press the ball joint right down through. I'm just tightening the press and then I hit it with a hammer at the same time, and that just kind of helps to break the ball joint free.

On the left is the old ball joint; on the right is the new one from 1A Auto. They do look similar, but there's some slight differences. However, ours will fit exactly the same. Remove the nut from your new ball joint and then you want to just carefully pry this boot off. Then set up your ball joint press and push the ball joint back into place. Again here, I'm going to tighten it up and just use the hammer to shock it a little bit to help it work its way in.

Once it's all the way back in, just replace that boot and make sure it's on all the way. Take your snap ring and put the snap ring along the top and make sure it's all the way down. Now take your wheel knuckle and you can remove the nut at the top holding it to the upper control arm. Then you want to feed your axle through while putting it back on that stud for your ball joint. This can take some maneuvering, but it will go, and then when you get enough space in the lower ball joint, you want to just replace that nut so it will hold it in place there.

Now push your upper control arm back into the wheel knuckle and replace that nut. Take your outer tie rod and push it back down and into the wheel knuckle and replace that nut. Then you want to torque that to 50 foot-pounds.

Push your new Cotter pin through, or your old one if you managed to save it, then just bend the tabs in opposite directions. Torque the upper ball joint nut to 50 to 55 foot-pounds.

Now replace the axle nut. Tighten it preliminarily. Put a jack underneath your steering knuckle and this basically raises the knuckle onto the ball joint to hold the ball joint in place. You want to tighten that nut up to 70 to 75 foot-pounds, and then further if you need to, to get the Cotter pin through.

Now, you can lower the wheel knuckle and then twist in your grease fitting at the top of the ball joint. We actually end up putting in a 90-degree grease fitting so it's a little easier to grease, and just tighten it up with our 7mm wrench. Then, just top the ball joint off with some grease.

Now you want to replace your sway bar link and you could see that ours was badly destroyed, so we're going to use a new one. You just slide it up through and the order is washer, then bushing, then the lower control arm, then bushing, then washer, then that metal tube, and then another washer and another bushing. Then it should be the sway bar, but you can see that the sway bar is just a little bit too low, so if you jack up the other wheel, you can see the sway bar go up and now you can fit in that bushing. Push the sway bar link up through the sway bar and then do another bushing, then a washer and then the nut. Then just lower the other side and it will compress the sway bar link and then just tighten that up with your 15mm wrench and 15mm socket and ratchet. For your final tightening of the stabilizer link, you can see I've got the vehicle on the ground, and the jack's underneath holding the suspension up in its usual ride height, and then I want to tighten it up so that the bushings basically come out to the same spot as the washers, basically compress the bushings down.

We'll fast-forward as Mike replaces the wheel and then replaces those lug nuts and just tightens them up preliminarily. Then lower the vehicle and torque each of the lug nuts to 100 foot-pounds in a crossing pattern. Then torque this 30mm nut to 184 foot-pounds, and then just replace your hub cap.
