Beware: long fragmented post ahead. I tried to describe everything I thought important.
I just installed a GC kit and all urethane bushings on my car, now I've got this vibration from the right rear. I think I may have had it before but with 200k mile rubber bushings, I probably wasn't feeling it. My tires were well out of balance and the car rode smooth, not so much with the urethane bushings installed.
Anyways... I checked all fasteners over the weekend and found that my subframe bolts had loosened. I retorqued the entire rear suspension.
We replaced the CSB, but we marked the DS and made sure it went back together as it should've. We even found old scribe marks that matched up.
That brings me to where I am now. I have a vibration right rear under load that gets noticeable at 40mph. Under hard throttle the vibration increases. In neutral it almost goes away. I can accelerate slowly without getting the vibration and cannot feel the vibration at all below 35mph.
I read that this may be related to my diff, I did run for about 6k with used up friction modifier....
One last thing, it seems as though whenever the rear gets loose, it wants to slide to the right. The car doesn't pull at all, but maybe my right trailing arm is somehow tweaked? I'm thinking I may take it for an alignment check.
Suggestions?
