Rear Diff Issue

[Cubieman]

Can all 3 diff. bushings be replaced in situ? The rears I can see, but not the front unless the subframe and/or diff. is dropped. Looking to do the power flex bushes. I have 4.10 gears and get a pretty good clunk here and there. The diff. was rebuilt with 4.10s in 2015 by an indy shop by the previous owner, wish I had more information on it.

Yeah you can replace the front diff bushing without dropping the subframe but it's a bit of a pain since there's not too much space. Also know that poly bushings add significant NVH. I've got some on my car and the diff whine is pretty loud. I'll probably go back to OE soon.

OP: make sure the rear mount bolts haven’t loosened.

I will just do the OE bushes then, I liked the poly because it looked like the install may be easier. I'll be putting it in the air today to check the rear bolts and everything else.

If the front bushing was gone it would be readily aparant when you have in in the air. The front of the diff would move if you shake it. What normally happens is the front diff bolt backs out thus ruining the bushing.

If you want to go OE rear bushings you need to get the whole diff cover. Cant buy OE replacement bushings. Some claim the E36(?) ones can be pressed in but not sure what the conclusion on that was.

It's up in the air, the front bushing looks fine, the rears not so much possibly. When I try and move the diff by hand it is rock solid.
The driveshaft has about 1/10th or so rotational play, the passenger side halfshaft has a small about of up/down play whereas the driver's side is rock solid.
The guibo has a few cracks developing in it, also if I rotate the rear wheels backwards then rotate them foward quickly it feels like there is some play there as well as a clunking sound when I do that.
