So you had that "clunk" when driving through a pothole, up the driveway
etc ? and that "death wobble" when driving at +- 50mph and hit a bump
just right ?

I have an early 93. You probably had to replace the whole bearing
assembly...right ?

ok

when driving 65-70 + mph then it seems to not do that (I figured that

right. Thing is how to figure out what it is I need to fix.

tire pressure is fine

I replaced this one. it seemed to be better.. but started again after
a while.

I replaced those a while ago (but quite a while ago)

hmmmm

tires don't really seem to have a runout

I noticed mine the most because of the brake pedal. When cornering, the
rotor pushed in on the caliper piston so the first hit on the brake
pedal after that was low, the next pump it would be back up to normal.

Mine didn't clunk, but I got to it before the wheel fell off... ;-)
