Where is the play coming from?
You just checked wheel bearings and TRE's and declared them tight.
That leaves:
1) the bushings:
Panhard upper and lower
Radius arms 2 front and 1 rear.
And
2) the king pins (knuckle bearings). I find it helpful diagnosing these to jack one side up, not far...
Hate to be the one that goes right to worst case, but here I am... Could be a bent axle. The only thing you can adjust with just tools, not counting new parts, is toe. That's it. Everything thing else is hard mounted.
