Which way do the upper ball joints thread? Left or just normal screw in right?

Righthand thread. Just start it as straight as you can and crank it down. There is a torque spec in shop manuals that it needs to reach to be tight enough. (If it keeps spinning brfore that torque is reached, the arm is no good)

Get out the welder bet you have to do some tacking

I spent a couple hours and used enough PB blaster to kill a horse. Been working on the front end since 10 this morning. I've decided the only way to get this done is to take the socket and control arm with me and have a shop get the damn thing out. Might as well do the control arm bushings at the same time too.

I have used a 3/4 inch breaker bar with a 8ft pipe to break it loose.
and the last car I did, I used my IR 2131 1/2 impact set on KILL and they came out...no fun..
the bushings are no fun either...

The first ones I took out I used good size pipe wrench with a pipe on the end. They came out hard. New ones went in easy, used the same pipe wrench without the pipe.

Remove upper ball joint with an impact wrench. That's what a repair shop will do.

Remove/install UCA bushings with a large diameter threaded rod, nuts, and spacers. Not a snap, but not too hard. Or use this kit:

It may very well be harder to get it out if you remove the UCA from the car. Use an impact wrench and heat, it will come out. When installing the new ball joint use care to start the threads evenly. Mininum torque is 125 ft. lbs. I shoot for 150.

I removed my old ones with a pipe wrench.when I put the new ones in one side I was able to thread all the way in by hand but the other side I needed a socket ($27.00 at NAPA,they had it on the shelf)since the 1 side went in so easy I just had both tacked in after torking for safety.if i ever have to replace them again i will probably just buy new upper control arms.
