I recently got my 2004 R53 aligned and the shop told me the left ball joints were bad so I replaced the left inner and outer myself then got it realigned. The problem I'm having happend about a week after the alignment which is every time I accelerate no mater what gear the car jumps to the right by itself, I put it in cruise on the freeway and when the car starts to accelerate when going up a hill it jumps to the right and then back when it lets off. Please help if anyone knows anything about this thanks!

 

re-check the the ball joint to sub frame bolts. They can back out if not torqued properly.

 

Torque steer a possibility here ? 04 had no LSD and torque steer has been an issue for me as well.

 

Haha what do you know, just pulled it apart and the bolt is backed out a bit, I'll try torqueing it right and see what happens, thanks For your help

 

Thanks a lot! That was it! Just finished putting it back together and it goes as straight as an arrow, I've been worrying about this for weeks just know that I didn't torque it right

 

Scary. Always correctly torque bolts.
