A-body Lower Control Arm

A-body Lower Control Arm - 10/15/10 12:32 AM

I did a search and didn't see this, But when putting it back together does the LCA need to be in a certain position, such as with the t-bar adjusted, before you tighten the nut holding it in the K-frame? Using Moog rubber bushing and not poly, so don't want to put too much twist on the rubber since the pressed-in rubber ones supposedly don't rotate like the poly ones or does it make any difference?
I put this job off for several years because of all the internet hype and posts about removing the lower bushing sleeve- And it was a non-event. Removed the shaft with a piece of 2-inch pipe and some washers like mentioned in previous posts, pulled out the rubber,then cut a groove straight up the inside of the outer sleeve with a 1/4 die-grinder with a 1/4 inch steel bit. Only took a few minutes and hard to cut too deep because a feather edge appears when you are just barely cutting through. Then just tap it out with a small punch- If you cut a groove on each side the 2 halves would just fall out...

Put it together and set on the ground and adjust ride height. THEN, tighten the nut.

The bushing will be under tension and likely to tear if you tighten the nut with the control arm at full droop then set the car on its tires.
