rdmt,

If you really have 0.5" toe-in in the back, and you're using a tie-bar, one or both of your lower control arms is very likely bent. That assumes that all of your bushings are really concentric.

Yes , I really have 1/2" toe on the rear. Yes there is a tie bar and yes the bushings are new and concentric to .0005 and no the control arms are not bent.

How do you know? Have you measured? On an undamaged lower control arm, the inner and outer pivot axes should be parallel.

If you are correct, the lower pivot axes must not be parallel due to invalid spacing from the centerline of the car. You're using a tie-bar at the back, correct?

The only other thing I can think of is a twisted hub carrier. Not likely on an aluminum casting. In 1000 cars, I've never seen one twisted but unfractured.

OK,,,, not to be a smart (or dumb) ass , but this isn't my first rodeo. Everything and I mean EVERYTHING has been measured within an inch of it's life. The arms have been switched side to side, The hubs are identical side to side. The ONLY thing I can fathom is that the brackets that bolt to the carrier somehow are align bored a bit off. The ONLY thing I can find is they the fulcrum shafts didn't quite line up with the holes drilled in the cross member of the frame but then the height of the carrier was off about 1/16 too. I contributed this to the welding jig it was built in. The carrier was out of square to the frame by around 1/8" so I slotted the holes a bit to square it to the thrustline of the frame. My next move is going to be to shim the front of the brackets at the carrier to spread the toe out.
