I've been having a grinding/vibration feel in my truck the past 6 months or so at very slow speeds turning corners and it seems to be getting worse. It seems to be worse when making a right hand turn compared to a left hand turn. I've changed the rear end fluid and added plenty of friction modifier. I've also changed the transfer case fluid and seal. The transfer case fluid was a little low and light brown. Neither of these has fixed this problem. Definitely feels like it's coming from the rear of the truck.

Anybody have an idea what could cause this?

Check the front hubs. Jack the front tires up off the ground and spin the tires. If you hear a grinding noise or if it's hard to turn then it's probably a hub going out.

 

Thanks BB. I'll check that out tomorrow when I have some spare time.
