rear wheel alignment

[pgurnee]

Searching has led to info on the front end alignment (the post by Chris on the front end was a work of art) but I have not found anything about the rear end.

I know there are adjustment grooves in the control arm brackets for camber and toe. On my van there is no adjustment left in either groove and the tech says he can't set the alignment to where it ought to be.

Seems those grooves can be made a bit longer to get a bit more adjustment. True? How long is reasonable? Is it necessary?
Thanks

Seems like either your rear lower control arm bushings and/or wheel bearings are the likely cause. You should first check the condition of the bushings and wheel bearings to see which has play in them. If you haven't already, replacing these with new will help your tech to be able to bring your rear wheels to proper alignment specs.

Got it up on the rack this afternoon.

Both the exterior trailing arm bushings had excessive play in them.
I never thought of those big pieces of rubber wearing out...
Thanks
