Thanks to CBphoto for this great write-up! Follow the instructions here, replace the seal and then backwards!
If you need pix, PM me your email address and I'll forward the Word Document so you can have the pix and description. I keep a laminated copy in our rigs so we can do trail repairs and still have directions that don't get wet and sloppy!
Tools required- high-lift or floor jack, small bottle jack, 36mm socket, 1 1/16" socket or wrench, 13/16" socket or wrench, 10mm wrench, 18mm socket or wrench, pry bar, large flathead screwdriver. After loosening the axle nut, jack up just a little with floor jack or high-lift, then use the bottle jack to raise lower control arm for removal of wheel and/or seating the lower balljoint.
"I think I covered it all here, not hard to do at all. To begin with, you want to just barely jack the truck up from the center frame in front, then use a small bottle jack under the lower A-arm to raise it slightly when you need the extra hand!
First, loosen the Axle nut while the wheel is on the ground (36mm) this is probably the only tool you'll need to add to your kit. Then raise vehicle, and remove wheel & tire.
Then remove the Tie-Rod nut (13/16")
Apply hammer to tie-rod, it'll pop right out.
Next remove upper ball-joint retaining bolt & nut (both 18mm)
I said REMOVE, not loosen...there's a retaining notch in the ball joint to keep it in.[/QUOTE]
Now remove lower Ball-Joint nut (1 1/16" socket)
And hammer out the lower ball-joint (with nut on to save the threads)
Hammer a screwdriver carefully into the notch at rear of upper ball-joint to help spread the gap.
Hammer the steering knuckle off of the ball joint (note piece of 2x4 wood to help keep upper a-arm from moving)
Upper ball-joint is now removed, notice notch to keep it on the bolt.
