1983 positive camber
 

I was driving my rx7 the other day and I slid into a curb. The front left wheel hit the curb at like 10 mph. Now the left wheel has some slight positive camber. If anyone could tell me how to start I would really appreciate it. I have already tried adjusting the strut so that the arrow points inand back. The ball bearing seems fine but any kind of tips to diagnose my issue would be greatly appreciated.

Take it to an alignment shop.there may be damage that you as a regular lay person..can't see!

Also,you NOW have sufficient posts to go to the 1st gen Specific section.So your tech questions can be answered more quickly there.

The starting point would be to take off the wheel and carefully look for any damage - such as a bent control arm or tie rod end. Replace damaged parts as required and get it re-aligned.

Should be very minor damage so it may be difficult to spot. You may want to get a good shop to inspect it as previously mentioned.

Thank you guys! I plan on just taking it to an alignment shop but had hoped for an answer on how to do it on my own first.

At 10 MPH I wouldn't expect much major bending. A tie rod would cause improper toe, not camber.

Perhaps the bushing on the control arm was already marginal and the impact pushed it back, moving the whole control arm towards the center of the car.
