So I've installed my whiteline lower rear and upper rear control arm. Immediately after the install, I noticed that there is now gear whine coming from the rear diff. I was already expecting some increase in NVH but I wasn't expecting things to get this loud. It's not TOO bad, but it's beginning to get a bit annoying. I hear it while on throttle at all rpm's in higher gears, so freeway cruising etc. Throttle off = no noise. Any amount of throttle = medium to high pitch whine coming from the back. Normal driving on the street, I do not notice it unless I'm up in 5th.
I had the installer look it over, and there's nothing rubbing etc. Pinion angle looked good. Had the dealer look it over while the car was there for something else, they too said everything is up to spec settings wise and pinion angle wise.
With how nice the car handles now compared to before, I'm willing to live with it but I'd love to get rid of some of the noise if possible. Has Anyone else noticed gear whine from their rear arm installs? Perhaps it's not normal, I do not know for sure (have not had a chance to compare with any other boss 302 on similar suspension setups).
I'm going to add some dynamat material under the rear seat in hopes that will help a little. I have heard that our diffs / final drives are noisy anyway, and stiffening up the rear will only make noise and vibration more noticeable.
Any thoughts, ideas etc? Should I be at all worried about possible extra wear and tear on the rear end, gears or driveshaft etc?
