Ball Joints U-Joints Wheel Bearings & Axles
This week I'm doing the project, and yesterday took off most of the parts. I still need to remove the ball joints and u-joints today.
I was surprised to find that the seal on the axle didn't meet the body and the axles are that rusted.
When I put them back in, is there a trick to seating these seals again to prevent water from entering that axle cavity?

It lets more than just water in. Mine had mud and sand in there as well. I used a threaded rod I had with a big fender washer attached to pull all the crap out before re-assembly.

That happened to mine, too. And, with the axles sleeved and a dust shield on the outer part of the shaft, that muck stay trapped in there until the mud wore a groove into the Chromoly shafts, causing front seal leaks. Fortunately was able to turn the shafts and replace the seals to stop the leak. Fellow who did the machine work--old time off-roader, suggested to never seal those tubes off because they always let muck in, but not back out. Instead, fill up the area next to the inner seal with marine grease--lots of it--to keep the muck away from the seal. That's what I did about 75K miles ago and haven't had a problem since.

I pulled a front axle from a JY XJ and it had a large groove worn in it too. So bad I couldn't even use it so I've seen what can happen.
I read they have aftermarket shields that are supposed to be better but haven't seen them yet.

Guides @ 2 each, dust cover spins freely, not water tight, got it. I'm flushing the pumkins and replacing the diff fluids after I get the rest of the job completed.
So I got both ball joints off one side, and the Synergy upper and lower back on and straight using a shim. But the other side, holy freakin . . . I can't get it, I've worn myself out. I even ejected the inner shaft hoping that might help, but it's a no go. I have a 1\2 bar about 30 inches long and even with a little cheater extension, I've gone as far as I have the strength to go, I can't make a smidgen of a turn more.
Maybe being under pressure over time will help it budge, but at this point I'm dead in the water with the project.

Thx guys, I just needed the torch and BFH, it's done now.
I have 2 different ball joint sets.
4 pressed out, 3 pressed in . . . I'm running out of gas for the day.
