Hey bud, you just keep typing and bashing your brains in...

Regarding the sleeve being tight. this is what i did before installing the new upper control arms.

I took the old bolt and pushed it through the old upper control arm, while it was dismantled from the car. It had no resistance, was free floating.

I took the new arm out of the box and took the old bolt. I tried pushing the bolt through the bushings and found that it had some interference. I could not make it pass through the new part. Tried from the other side and had a similar problem. Looked through the hole and saw something that did not look like a lined up thru hole. If it was a tunnel that was being constructed from both sides of a mountain, they missed the center point by "that much" Pulled one rubber end out with the bushing inside of it and tried passing the bolt through just one piece of the assembly. The bolt got stuck. Next I measured the outer opening as well as the inner opening, the diameters of the ID. They were very different. If my memory serves me correctly the bolt was .470". The outer dia was a little more than that and the inner dia was .462, therefore the bolt would enter the bushing but it would get jammed in the "taper"....

I was actually going to swap out the old bushing/rubber sets but decided to ream out the new ones thinking that the new rubber was more important than the hole size, not that I was actually altering the hole size, I was just correcting a manufacturing problem...

Next problem that I have it that the inner piston on the right side caliper was really hard to press in with a c-clamp. I have noticed in the past that the right front tire was harder to turn when the car was up off the ground, so I guess that the inner piston has been stuck for some time. Should I try rebuilding the caliper or get new front calipers, plural.... ***** NOTE: Front Pads were paper thin, I mean they were probably .030" thin on both sides of the front of the car... Perhaps the projection of the piston, that far, has something to do with the sticking of one piston in the right side caliper.
