Odd tire wearing
 

The inner side of my rear tires are wearing faster then the rest. It is happening to both side at about the same rate. Like if you mess up the camber on an IRS.

My axle doesnt look bent, I'm thinking it the control arm bushings but its still very confusing.

Any idea's?

Which vehicle? If its the truck a locker will cause the wear you're talking about.

Ya its my truck. I only have a posi in the rear.

Posi/locker, same result.

I don't really chirp around turns. so its hard for me to understand how that is causing extra wear

Dont have to chirp to have that wear pattern. The guys with the detroit lockers get it especially bad, my car makes some pretty weird noises in a tight turn with a torsen lsd. Clack clack clack. Tis the nature of the beast
