Momentary unbalanced power to rear wheels
Have an issue that I'm trying to diagnose and open to input. Lately I've noticed what feels like uneven power to the rear wheels. I'm only feeling it when cruising or coasting and then applying throttle or even on decel without breaking (just letting off throttle). It feels like the one side is momentarily going faster causing what I can only describe as slight "fish tailing". I thought I might have a rear break caliper not fully releasing so I removed the calipers and cleaned up/relubed the guide pins and pad shims, but that hasn't worked. While I had the rear axle on stands, I rotated each wheel by hand and didn't feel any excessive drag. I've applied full breaking going from 60-0 and can not feel any pull. I've also thought it might be worn rear lower arm bushing (SR Performance poly arms) causing the rear axle to momentarily get out of square. I haven't yet had a chance to remove and inspect them yet. Another thought I've had is the limited slip clutch packs may be worn out. I changed the diff fluid about 60k miles ago with RP with friction modifier. At this point its just a minor annoyance but, I'm open to other items to check.
