I jacked it up and could see the control arm move quite a bit before the spindle started to move, and the opposite when setting back down. Ordered a pair of MOOG lower ball joints and a ball joint press. Tool got here yesterday so I dove into it today. Didn't even get started and didn't have a socket to fit axle nut, but AutoZone did. 1 1/4" deep well $14 plus 25 mile round trip. Got everything broken down to use the press and pushed the old joint out. When I took the spindle loose, I discovered the uppers were extremely worn too.

I figured that on alignment, especially the way the right upper arm is designed. I was also told by a fellow Explorer/Mountaineer owner to have it at ride height when tightening upper control arms at frame.

Stormy weather this weekend slowed down my progress, but I have managed to get the left lower ball joint pressed in, and the nuts off the upper control arm bolts.
