Best Bushings

[heinzboehmer]

Has anyone gone poly diff bushings and gone back to oem?

Seems like everyone here who did poly bushings in the diff has gone back to OEM (myself included).

I am looking at powerflex bushings right now for the rear diff. this is an HPF car and I figured the Poly bushings would be stronger then the OEM, and about half the cost. This thread is making me think differently. Has anyone ever posted a before and after video?

I have the AKG 95A and there is definitely a hum at higher speeds...not a fan of that. I think everything else is OE in terms of bushings except trans mount which probably isn't helping either...I too plan to go back to OE when I get a new diff and refresh cv boots

Once I added more sound deadening (light weight closed cell foam) under the rear bench, and knocked down the majority of the whine, I've been very happy with AKG 95a poly for diff. It gives a much crisper power transfer, thought hat's coming from older, 140k miles stock (foam) bushings so I'm not sure if fresh oe foam bushings would be much better or not.

I find this at front diff bushing location. Early MY? Lots of rubber, but I also had e36 style rubber bushings in thr cover

I had an 2001 in a while ago where I saw this style bush.
Both the front bush and the ones in the cover were changed from 02/2002 according to RealOem.

This thread is "best" for street and controlling nvh. For track you can go solid everywhere or not care.

034 motorsport is a recent option which seems to be solid rubber (no fluid fills) that could prove stiffer but no nvh penalty for folks. I haven't tried them yet, but curious if anyone else has.

Saw those too, have had mixed results with 034 quality products in the past with Audi aftermarket, fwiw.

I just bought them based on some research and video by FCP. Haven't installed them yet. I have to deal with the starter first now ...
