upper A-arm shim placement - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Rebuilding the front suspension on my 69C10 and now that I am putting it back togather I cant remember the order of assembly for the upper A-arms, I think it was the a-arm, spacer, shims and then the nut, but I cant remember and forgot to take a picture of it, could someone snap a quick pick for me?

From the fixed mount @ the frame-rail, the spacer & shims go first (behind the a-arm cross-shaft), then the shaft, then the nut is last.

I`m just waiting on the new shims from Jim Carter parts, zinc plated

, but I should have the arms, upper and lower done today with all the cols, shocks ect. I`ll just wait to put the tires on until the shims show up. I powder coated the frame and a-arms and did it all with zinc grade 8 for a clean look like yours.

what is the purpose in the shims right there? my passenger side front tire sticks out further than my driver and i was wondering if i could just take these shims out to give myself a little more clearance. thoughts?

They set the alignment for the wheels. Just pulling some out w/o verifying the alignment settings can cause improper tire wear. Specifically, the shims impact caster (relationship of the upper & lower BJ's compared vertically) & camber (top of the tire leaning in or out).
