so last winter i side hit a curb and since then the car started pulling to the right, i've done alignment but that didn't help... what else could it be?
Lower control arm, tie rod, cradle?? More than likely prolly just a tie rod or, a lower control arm though.
Who did your alignment??
Anyone doing an alignment should be able to see any damage that might cause something like this. Did you tell them it was pulling to the right when you brought it in?
Are you sure it's pulling to the right? Did you ensure you were testing it on a level road and not one that's sloped to the right for drainage?
How long was it doing this before you got the alignment? Driving with the bad alignment could have caused uneven tire wear which could result in having it continue to pull even after the alignment is corrected.
WW summed it up rather well.....
