2004 Nissan Altima Base Model Automatic Transmission Front Passenger Side CV Axle Assembly TRQ CSA82321

Before you lift and support the vehicle, loosen the lug nuts with the wheel on the ground. Use a 21-millimeter socket and breaker bar. Lift and support the vehicle. With the lug nuts loose, you can use the 21-millimeter socket or just your hand. Finish removing the lug nuts. Remove the wheel. Place it aside.

You need to remove the center cap from the wheel. I'm going to take the end of a screwdriver, put the hand on this side and just give it a good whack. Your center cap will pop right out, it's spring-loaded. We'll put that aside.

Remove the cotter pin from the axle using some needle nose pliers. Spray this axle nut with rust penetrant.

Now we're going to put the wheel back on, put the vehicle on the ground. We have to loosen this axle nut with the weight of the vehicle on it so the wheel doesn't turn. I'm just putting these on snug by hand. The vehicle's not going to roll anywhere. We're just going to put it back on the ground. Simply don't want this thing spinning as we're trying to remove it with a breaker bar. Use a breaker bar and a 32 millimeter socket on the axle nut. Break it free. With the axle nut loosened and the vehicle lifted and supported, again, we can remove the wheel to continue working on removing the axle.

To remove the cotter pin, I've got some needle nose pliers. I'm going to try to bend it straight. Sometimes you've just got to grab it and wiggle the cotter pin back and forth and you'll start to see the looped end move and it's freed up. Kind of work the needle nose into it. So pry against it. When these cotter pins get rusty it can be a bit of a pain to get them out. The other trick is to use some side-cutting pliers. Sometimes you get a better grip on them on the cotter pin with the side-cutters and just work it out. Or like that. It actually cut the end off of it. Sometimes you can just cut the looped end right off. Then go back to your needle nose pliers and it's easier because you should replace these cotter pins every time you take this off, and try to slide. Grab one part of the cotter pin. This one's just going to break on me. There we go. I've got it out.

With the cotter pin removed, I can take a 22-millimeter wrench and loosen the nut. This one's on here really tight, so I'm going to take my dead blow mallet or you can use a rubber mallet on the end of the wrench. Just going to hit it, break it free. This is almost off. You really can't get a socket and a ratchet in here. If you've got a ratcheting 22-millimeter wrench, you could use that. I just have a regular box wrench, so just turn by turn, get the nut loose and off.

This control arm is made out of aluminum. It's very soft. You can try to hit the knuckle with a heavy hammer to break this out of the taper, but you could hit the control arm and damage the aluminum, so you really should use a ball joint separator tool. With the ball joint separator tool in place, I'm going to use the appropriate size ratchet and socket. Just going to gently push it out. It will snap when it comes free. Now we can pull this down and out of the way. It should come right out of the taper.

With the lower ball joint separated from the knuckle and the strut and hub assembly, we're going to remove the axle nut that we already loosened on the ground. It's a little tight. I can use the socket. It's loose. It just has some rust on the threads. I'm just going to use this to take it off. I spray some rust penetrant in here, where the splines go into the hub. With any luck this will push out.

It's kind of seized in there. I'm going to take the axle nut, put it on, take a dead blow hammer, and try to pop it out. Spray a little more rust penetrant from the backside. I've got the nut on here so that I don't mushroom the end of the axle shaft as I try to knock it out. That's as far as it'll go with the nut on there. Pull out on the hub and axle assembly like this. Push it out.

Hold the axle. I’ve got a drain pan underneath in case any transmission fluid comes out when I disconnect the axle from the transmission. I've got a small pry bar. I try to go between the subframe here and get this pry bar up and just sort of pry it out of the – there's a circlip inside that locks it in and you just snap it out of that. I'm going to use the pry bar. It's a bit tight, the clearances. There it is.

We did have some force holding them in. What's happening is there is a clip here. This clips inside of the transmission. You basically just need to pop it off of this circlip and then it slides straight out.

This is our old CV axle, pulled from our vehicle. This is our new one from 1AAuto.com. Our car originally did not have ABS. The new CV axle works for cars both with and without ABS. It already comes with the tone ring. See they're the same. They are the same length, with the same style splines and circlip, same spines here, same threaded ends, and it comes with a new axle nut. This should go right in and get you on the road.

Before we try to install our new axle I'm just going to take a rag and just clean out the splines that are in here, just any loose debris. We are losing some fluid here so when we're all done you want to check and fill the transmission with the appropriate fluids the correct level, but for now I'm just going to check the condition of the seal. It looks good. I'll wipe out any dirt that's in here.

Take our CV axle, then guide it in, careful not to nick the seal on the transmission. Seems to be lined up on the splines. I'm just going to try to push it in to lock it. Try pushing it in. It's pretty stiff because it has to get over that circlip. I'm going to put our nut in the end here so I don't damage the end of the axle shaft. Use a dead blow or rubber mallet. I'm just going to tap it in. There it is. Now it's seated. It just need to be tapped a little bit.

I'm going to take this axle nut off. Take a little bit of rust penetrant or if you got some white grease or something. Now we're going to take our axle, bend it over as best we can, and push out the hub. This would come together. There it is. Push it back.

Capture our axle nut. Take that big 32 millimeter socket and I'm just going to thread it down by hand to pull it in. Switch to a ratchet to go a little faster. Okay, so right there it stopped. That's fine because I will torque this after the wheel's on the car and the vehicle is on the ground. I just wanted it tight so I can put this back together for now.

Put the ball joint back into the knuckle. If you need to you can – there you go. We'll put our nut on here. Tighten our ball joint nut down with a 22-millimeter wrench. See, it's pulling these together. It's going to pull the ball joint up into the taper of the hub. That helps to lock it in place. I'll get this nice and tight and then put a cotter pin in. Put our cotter pin in. Take some needle nose pliers. Bend it over. The ball joint is now tight.

Reinstall the wheel on the vehicle. Start the lug nuts by hand. You need to torque the center axle nut The torque as 173 to 230. I’m going to torque it to 180.

Try to reinstall the cotter pin through the wheel opening. It doesn't really fit so unfortunately you have to take the wheel back off, but is the best way to do it, is to torque it with the wheel on the ground on the car. Reinstall our cotter pin. Bend it over. Now we can clip our center cap back into place. We'll reinstall our wheel and we'll torque the lug nuts. Torque on the lug nuts is 73 to 86. Let's torque these to 80 in a cross pattern. The job is complete
