Whenever I accelerate faster than normal, it feels like the rear end rolls (rocks) back. I'm thinking it may be a u-joint going bad. My parents 07 Tahoe does the same thing. I searched on google and found possible u-joint issue and "dry" input shaft on transmission. Anyone else have this and fixed it?

Have you checked all the bushings in the trailing arms going to the rear axle??? There are 8 of them. 2 lower trailing arms and 2 upper trailing arms with a bushing at both ends.

I feel the same thing and was worried it may be u joint related. Since it can be controlled, havent dug too deep...yet.

Is it a feeling of delay with or without a clunk sound? If so might just be time to change rear end fluid while you check the bushings k mentioned

Don't google, crawl under there and have a look around!
