Here’s a mystery for you guys. 2004 Jeep grand Cherokee four-wheel-drive with a six cylinder engine. I have a pretty bad noise or wobble coming from my jeep in the rear when I apply brake pressure. And there is also a clunk when I go over bumps and it’s definitely coming from the right side because if I hit a bump with just the right side it makes a clunk and it doesn’t do it for the left side. When I jack up my rear tire I noticed there are some axial play and also radial play in the bearing. I replaced the bearing and seal had it pressed on and everything. I put it back together the problem persists and I still have the play! I don’t understand what happened? I need to replace the end plate flange? Do you make shims for the bearing? I couldn’t find any

Easy to overthink some of these problems. Start by proving where the noise is really coming from. Noise OR wobble, you say? Which is it?
What I have found is loose lug nuts will do that when you brake. More like a thump thump. I would also , obviously , look at the brakes.

The 2004 D35 is not a c-clip as you know when you replaced the bearing and does have some axial play, at least mine does. There shouldn't be any radial play unless the bearing spun and wore out the housing. It's possible the retainers are worn as well. Now I'm going to have to find the specs on that.

I just spent over a half hour going thru my FSM and there is no mention of any axial play. Doing some more research because I know My jeep has some.....

I've got to find out about this.

Time for an update. So I ordered a replacement bearing seal and flange. I noticed there’s a difference in thickness between the old and new seals. This is a big deal since the seal is what actually pushes against the bearing to provide the seating thrust for the taper. I think there are two different kinds of seals and if you use a shorter one it introduces a lot of axial play and therefore radial play which I have observed
I will update the thread with the results this replacement. This time I ordered the Spicer complete set so we will see

After talking with some jeep mechanics, they concluded that the seal wasn't think enough. AGAIN it pays to buy Mopar, doesn't it?

I replaced the bearing and seal and flange with the Spicer but I use the thicker seal from the old kit and my problem went away , heads up to all you jeepers !
