I found I had a bit of a wobble. Tires balanced, alignment is perfect, etc.

So I went hunting.

Guess what? Part #52392A (Diff support arm) is cracked clean in half! It has enough pressure on it to keep it in place, but it is allowing the diff to move and causing the vibration.

I was wondering why I saw a rub spot on the diff near the pinion and had loading/unloading noises as well as a vibration no matter what I did.

Go figure. Looks like I get to wrench a bit. Probably a good time to find it. The inner clamp on my PS CV let go too, probably because of the same problem.
 
Parts ordered :p
 
now thats a first, take some pics Dan!
 
Will do. Seems like an extremely easy fix.

How about them apples.

New one has a lot more heft and was clearly redesigned.
 
Dang, I wonder what all contributed to it breaking? That new one does look beefier though.
 
I think it was a wear item. It was original from 2003 and there were several TSBs for vibrations, etc that recommended replacing this arm. I took that and had a look and saw the break. The sides of the break had wear where it had been popping along all this time.
 
Well, great find - sucks that it happened, but sounds like it's not an expensive fix; and all of us owners are the wiser for it now.
 
Yeah, I would recommend everyone take a peak, very easy fix and can cause some really confusing symptoms (vibrations) that can lead to balancing tires and alignment when it is not needed.
 
Swapped out my PS CV as the boots were torn from having too much play due to this break. Can't stress enough the need to check your diff supports!
