Poly Subframe Bushings

[cheades]

I am just posting to see about those who installed poly rear subframe bushings. Did you use grease when installing them so they wouldn't make noise?

[nando]

no need for grease, they don't really move around. my trailing arm bushings came with sillicone grease though, I used that and have never had squeaking.

No grease, no noise.

Fucking liar. No need for grease....actually used some epoxy.....but that's not the case.

They are loud and you get the differential whine like a mother.


If you want poly bushings and street the car, IE street.

I didn't get any more diff whine with mine, and really didn't notice any more noise.

[rwh11385]

Maybe my M coupe diff bushings helps increase it too. But the whine to start was loud. I got used to it though.

I am sure the diff bushing does add to it. I only have poly subframe bushings and stock TA bushings though. That might make a slight difference as well. What fluid are you running in your diff? I bet some Redline 75w90 with LSD additive would make a big difference.

[rwh11385]

yeah, redline in both tranny and diff.

I have a poly diff bushing (along with every other bushing), my diff is totally silent. something is wrong with yours...

what brand? Skafrog said it was nothing new and said people had returned RTRS bushings because of the noise.

There is a weird shifting noise when I get on/off the gas that has me curious. Might be the mount bushing. Ask Sean or Trevor about what it was like.

I have that same noise. Always have, even when it was auto.

[rwh11385]

okay. well, i had it too, but the bushings and likely the m coupe made it much louder. Sean said something like it was normal and said why, but I forget.



anyway. if you care about a quiet ride....dont install race suspension pieces. bottom line. :P

I got the diff bushing from bmwbushings.com, everything else is IE.

I have a clunk noise in the rear but I'm pretty sure it's because there are only 3 bolts holding my diff on.. :?
