Ok I'll bite where is it loose , is the ball joint loose in the control arm or is the ball joint pin loose in the ball joint housing ??

The ball joint pin is loose inside the ball joint housing itself.
Wore out way too fast. I pumped quite a bit of grease in them prior to driving.

The ball joint is loose in the control arm. It can be moved up about .25 before it hits enough interference to prevent it from popping all the way out.

Oh, I thought he meant loose in the ball joint housing, like worn out.  :-\ ?

OK
 You need to replace the upper control arms  or you could it then them down & weld them but the ball joint & arm will both be junk next time they wear out .

No No No!

Some confusion going on. Sorry about that.

The upper control arm is fine.

The ball joint is frozen inside to the upper control arm where it screws in.
I used a 3 foot cheater bar and it wouldn't budge. I'll use Brad's suggestion of heating it up.

The shaft that comes out of the ball joint has quite a bit of play in it after only 500 miles.
That is the only part worn.

Okay, my mistake. I thought the entire ball joint was loose in the arm.

if the ball joint is frozen then I assume these are not new ball joints ?

I would replace the upper ball joints, assemble the spindle without the dust boot and torsion bars, and cycle the suspension with a bottle jack and see if the balljoint shaft is hitting the edge of its cage before you reach full travel (or if its even close at full travel).

As for the suborn one... maybe a little heat?  :dunno:

That did the trick!

I used a pencil flame Oxy/Propane torch and it unscrewed with ease once heated.

And then to put the rubber boot seal on...
I firgured just put the ball joint socket on upside down and force it up onto the ball joit.
Worked perfect!

 :2thumbs:  Great it worked out ! Moog replacements? The new ones should screw in with "some" resistance.

If I run the taller F,M,J, spindle do I have to: (mandatory) use the Moog offset bushings?

I have Polyurethane non offset UCA bushings in it now.

No the offset bushing just allow you to get more/enough caster.
