Cadillac CTS-V - V pulls right under hard acceleration

My '04 V pulls to the right under hard acceleration, the harder you hit the pedal the harder it pulls, then when you let off, it pulls to the left, when neutral acceleration, it is straight. Any ideas? It has 90K miles on it. I'm looking at replacing the bushings in the rear trailing arm with the turninconcepts pieces. Thanks in advance for any helpful insight.

Rear tie rods.

Okay, are you saying they are bad, needs replaced, adjusted, etc....

Most likely your bushings. Unless you ran over something and bent it

Alright, I'll replace the rear trailing arm bushings.

Any of the above. Have you had an alignment shop look under there recently?

Mine pulled bad with the stock diff bushing, which of course was shot. I replaced it with the CS one, and now car pulls in a straight line.

New UMI mounts, new CS diff bushing, and full alignment, with road racing specs. Ah, wait, I had an alighnment done BEFORE the diff bushing and motor mounts.

Diff bushing and motor mounts should not affect alignment.

Sounds like weak rear shocks to me.
