Received my car back from Firestone after having the alignment checked out again.
Recently my front left inner tire's tread was eaten up, down to the steel wiring.


The mechanic stated that the Camber/Caster are off, he pointed that out when I got the first alignment. Today they told me it is now even worse.

I now have new tires in front but the mechanic stated that if I don't get new adjustable ball joints then the new tire will get eaten up as well.

My question: If it is the ball joints that need replacing, which ones would you guys recommend?

I took the car into get the alignment completed/checked twice.
Here are the results:

Is your car slammed? Are you the original owner? Has it ever been in an accident or hit anything, especially on the left side?

 

I knew I was missing information.. lol

I'm the 3rd owner(The vehicle was completely fine prior) I have had it aligned a total of 3 times, 1st time they didn't see anything wrong.

Cars completely stock, 06 AT.
No accidents, have hit a pretty nasty pothole on the right side.

 

Pretty sure something is bent. A stock TL won't require aftermarket parts to keep the front end alignment in spec.

 

Should I just take it to my mechanic and have him look at it?

 

As stated above, if specs are out of the factory recommended range, something is worn or bent. Probably bent the lower control arm as the caster is way out on the right side and camber can only be adjusted with the installation of a camber kit. Have the toe set as close to zero as possible.
