Type 85 Alignment - Caster Error Cause

[Doug Johnson]

The caster on my '86 4000CS q can't be brought into spec on one side.  My
only guess, regarding a cause, is that the sub-frame has been shifted.
Sub-frame and a-arm bushings were replaced a couple of years ago, but this
is the first time the caster has been reported as being out of spec.

Also, what would allow axial movement that I notice in my steering wheel?
I'd guess it's about 1/4" of play.  I'm dumb(founded).

Thanks for your thoughts!
