Front Upper Control Arm Replacement
Anyone have a link with directions on how to R&R control arms as well as bushings for a C4. Bought one from a guy and he said it had a ball joint loose. Turns out the bushings had worn and he was grinding his control arm on the shock.

I did the bushings a while back. These aren't the greatest pictures, but they should give you some idea. http://s48.photobucket.com/albums/f234/TPeye/

Don't have any pics on how to remove them, but here's how those tricky bushings get replaced. It's a puzzle for sure.

Or just tighten the bolts down and go? This will get you a suspension that binds up unevenly and rides stiff as hell.

Make sure the inner sleeve is clamped down when torquing the bolt to spec, and the bushing is free to rotate. The ID and sides of the bushing should be lubed, but it's a good idea to lube the OD also. Instead of narrowing the bushing shoulders, I narrowed my suspension parts on a grinder. Most people probably wouldn't be up for this though. It's possible some of the binding issues are due to poor GM tolerances on the aluminum parts. Could also be that the original rubber is just more plyable and doesn't bind up even though it's a bit wider than the inner sleeve.
