Lower control arm help.

Anyone know what this is to my control arm? It's bent and needs replacing.

Nevermind. Found it in haynes book. Says it's a trailing arm.

Hit a curb or something? Did you ever get your car running good?

Oh ya she runs great now. No problems in months. Ya I backed into a tree. My back window is covered in old tint glue from whoever owned the car before me and it was raining. The front of the tire is curved in facing the direction of the car now like if I was turning it with my steering wheel.

Rear end was sliding all over the road when I drove it (not far). Going to replace the trailing arm and lower control arm. Hopefully that fixes it.

Is it possible that I knocked the back tire out of alignment? Cause I replaced all the arms and it is still curved in.

It sure is. Should take it in for a full alignment. I personally like to take the cars in when I do any suspension work. But curbs will totally knock it out of alignment.

Ya Cause the tire hit the tree in same angle as if I hit a curb. After putting the newer arms on, it straighten it out a little bit.
