Bent ball joint?? Am stumped!
 

Daughter has a 1995 HOnda accord and hit some wet oil and slammed into a curb about a month ago on passenger side. Replaced axle, rim, tire, lower control arm, upper control arm. It drives straight for about 30 feet then the tire pull in towards the bottom and it veers off to the left. Mechanic thinks might be bent ball joint, but not sure. Anyone have any suggestions? She hit it hard considering she bent the darn upper and lower control arms and the axle. I should also add that when you back the car up again, the wheel straightens up.

Does your mechanic have a alignment machine? If he does , he should have raised up and took a look instead of guessing. If he has no machine-go to a shop that speaializes in alignment..They will know what it is. :)
