A couple of days ago, i wass driving in the rain and my car skidded out and slammed against the curb... >=\
i completely replaced the whole right suspension and everything for the right wheel, but ive noticed that whenever i turn, mostly happens when i turn to the left, the wheels dont return back into place, i basikly have to bring the wheels back to center manually.
im not to sure what might be the problem or what i might need to fix.. can anyone help me out with some ideas of what i could check in the car to see if its damaged or not, cuz im completely clueless ??? o.O

Sounds like something is over tightened or your strut bearing is bad. Check the tierod end to make sure it's not super tightly clamped down.

also your caster may be off. caster is what causes the forces to return your wheels to straight

ouch! yeah, same thing happened to me a few years ago too. Mine turned out ok though. Hope you can figure it out.

Need to be sure that alignment specs are with in range, toe, caster, so on. Strut Bearing will cause this alomg with the rack preload (was anything done with the rack and pinion ?)
