Suspension pulling right under acceleration

I'd say check the alignmet or tire pressure.... just a thought

Sorry to bring this back from the dead but I have a friend having this same problem so no need to rewrite it out. Has anyone found a cause to why this is happening? He claims that the rear end was fine and did good until a wheel bearing let loose now it has this problem.

Just to let everyone know he and his buddy's also took the K member down when they put the headers on but say it was still fine the til the bearing. But they said they took the K member down again and nothing changed.

The car is a 01 Cobra with solid rear swap. Summit uppers and lowers, eibach sportlines, eaton diff, 31 spline moser axles and 4.10 gears.

If you guys have any ideas please let me know I am trying my best to help him find this problem.

Thanks!
