cross shaft adjustments? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I believe the upper cross shafts are threaded for some front to back adjustment. Now this may seem crazy but can you just shift (adjust) these forward or back to get more (or less) caster? does it mess up the other alignments?
I would like to do the upper a-arms IF they would help the feel and drivability of my truck. I have a static drop only with spindles I dont know where my alignment is at right now but I had it done after all my front end changes.
any thoughts would be great!

there are 2 bolts on cross shafts. to adjust caster and camber you can add/remove "shims" you can buy them at auto parts stores to alignment shops.

loosen the nuts up +/- the shims then tighten them back up

I know that is how they are adjusted but didnt know if moving the cross shaft would help in gaining some caster then using the shims to get the camber back in place?
