72 Duster Resurrection

It prob will. The ball joints are threaded. They use a special 4 point socket to thread em in and out. Not sure how the powder coating will affect this. Most people changing out uppers will put 2 tack welds minimum, 4 tack welds maximum tacking the ball joint to the upper arm at the nut flats on the ball joint where it meets the edge of the threaded flange on the arm.

I definitely would try to sand as much of the powder coating out of the "threaded" section. Having done a fair amount if powder coating I would have protected the threads before applying the powder.

I wouldn't exactly call them threads, more like a suggestion of a spiral groove. Be extremely careful "threading" them in as they are easy to cross thread. Spot welding is a fix but that would kind of destroy the finish.

Oh, and I would not consider putting those rotors on without having them turned after all the work and money you've put into this.

hmmmm

Ok, I see how they thread into the upper control arms. That is quite difference than the Chevy world of rivets or bolts on ball joints.

Guess I will need to clean out the threads on the UCA's and the tapered holes on the LCA's. Small wire wheel? Sandblast? Will I need the special ball joint "socket" to install my new ball joints? I dont have a problem welding, but is it necessary if I feel good about the threads?

What about the holes that the actual control arm bushings go in? Im thinking the powder will interfere with new steel bushing sleeves getting pressed in...

I do plan on getting the rotors turned.
