Super Pro rear diff bushings - amplified noise
Hi, After having a set of these fitted to my 2002 sti there was a massive increase of "whine" when slowly down in gear at around 2.5k rpm..
If I accelerate the noise goes and I cant actually feel any grinding from the rear. The noise only seem to appear while in gear and slowing down - most noticeable in 4th. Is this a normal inherent of uprated diff bushings. I don't actually feel any benefit from having these. |
Yes.
The bushes used to absorb the vibrations. They dont anymore with the new ones. |
May go back to OEM.

I missed all the tranny noise etc when I went from a classic to a newage, replace the rubber prop bushes with solid if you want to add some noise !! |
I know where your coming from.. however if I were to sell it .. it would put buyers off..

Have to admit I really like hearing the diff whine after I replaced mine, but each to their own. Also noticed a real difference with feel once the linkage bushes had also been done.
Not sure I want to go as far as engine mounts last car I did that in the steering wheel looked like the legs on a fitting dog! |
check your suspension mounting points, see this thread: https://www.scoobynet.com/drivetrain...iff-whine.html

Sweet jesus - that's hardcore yet oddly satisfying.
