How many miles on the car?

What you need to do here is replace the rear balljoint, rear arm, and eccentric arm ( one that controls the toe bolt).

That basically covers the rear, when you go get an alignment get the camber dialed in as close to zero as possible and the toe zeroed out as well. It affects handling but i dont know if you push the ride or not.

Since my 4.8 is lowered so naturally i will have more camber cause of that and probably cause of the aggressive spacer setup i run as well, the closest i could get is about -2.6 degrees on both sides, and then i had the toe zeroed out.

Been on new rear tires since October and no abnormal wear. Car is driven hard as well.
