Grinding vibrating when it dips

Correct me if I'm wrong here: The transfer case and the front differential are mounted to the chassis. When the body jounces and rebounds, both driveshafts and both half shafts move up and down independently. If the body is lowered, something could easily contact any of them. Same holds true if front chassis ride height was lowered out of spec. Over time, not miles, torsion bars lose their lift allowing the body to drop lower.
you are correct... but he was referring to the front drive shaft which is stationary.. not half shafts.

I stand corrected, the front drive shaft shouldn't move with jounce & rebound. But the half shafts do, and something may be contacting them. Checking front chassis ride height wouldn't be a bad idea.

Exactly my point. The problem is, we don't know if it has a body lowering kit, or a suspension lowering kit, or a combination of the two.

OK.. I lowered this over 2 years ago. Did not do this for 2 years. Rode smooth. Just started doing this a while back. checked ride height nothing has changed. I so no points of contact.
I am thinking the bearing is moving and causing the rotor to grind if you will.
For fun I can raise the thing back up to stock top see if it goes away. Takes about an hour.
