Rear viberation
I got my rear end complete rebuilt last month, I am getting a weird grinding sound when I push the gas peddle half way to the floor only when I am taking off from a stop light or stop sign. A few days ago I was in a parking lot I fished tailed a little bit, nothing that aggressive no burning rubber, when I was driving up my street a can feel my rear end of my car floating or something was loose, I pulled the tires off checked my bolts on the rear stabializer bars they are all tight, I check the shocks and hardware on them too, All tight too, Then I noticed my coil Isolators upper and lower were torn and cracked on both coils, I am wondering if that would play a roll in causing the grinding on take off at the light or stop sign, Nothing grinds when driving on hwy or at any speed, Just when I leave the light at med peddle, lite peddle its doesnt do it. I checked the drive shaft too all tight univerisal joints feel tight too Any Ideas???????

RE: Rear viberation
you might want to replace all the rear end suspension bushings with new ones made of polyurthane versus the stock rubber ones. This will stiffen the suspension and lessen the twisting the rear end does under acceleration. new upper and lower control arms would also be a good idea, just make sure you get ones that can be lubricated so the harder bushing don't make a lot of noise.
