Diff Bushings

[Vas]

Just interested in hearing some more info in regards to replacing the diff bushings.

How many miles on the original?
What brand did you go with?
How was the install?
Any issues or noises?
Tools used?
Any recommendations?

Plenty of options out there for them. Let's hear some feedback.

I replaced them on a previous ZHP at 93k miles, with OEM bushings. They had hairline cracks observed during a visual inspection. I didn't notice the infamous noise or clunking that others have spoke of.

The install took my indy several hours. I think the bushings were only $30 each.

I don't know which tools are needed, but he did say they were sort of a pain in the butt.

Dropping the diff is the hardest part. I ended up buying the kit that I rented from a fellow local fanatic. Tried to do the subframe bushings at the same time. That was a royal PITA. I was only able to finish one of them before I said "screw it." They weren't that bad anyways on the 323. No torque=no damage. I should put that up on the tool loaner program when I get back. It has the tool for the 2 small ones and the larger one.

That might be a good idea. I would be interested in renting the tools since based on research, they make the job easier.

Oem Bmw bushings are $17 for the front and $60 for the rear.

I remember being in the $60-$70 range for both, assumed they were priced similarly.

the subframe ones were a pain in the but to do.. I had a shop do mine.

I opted for OEM diff bushings cause I didn't want to introduce more NVH.

I need to do my rear main carrier bushing on the diff... haven't done it yet cause I hear it's such a pain. Will prob go OEM or meyle depending on the price difference. Diff fluid needs to be changed while I'm in there as well

Wish I would've done the diff bushing when I swapped to a 3.38 but I plan on doing mine in the near future. Definitely going AKG.

AKG does make bushings but not sure how they are for the street and if they are worth it on a street car. Price iirc is around $140 for the 3 bushings.

For the pricing posted above, I got it directly from ECS for factory BMW parts.

My diff bushings were tearing at 110k, but thats with track days in them. I opt to replace the whole subframe with M3 at that point I think Vas should do that same hahah.
