Ok, did the old power wash maneuver underneath. Still a groaning noise on take off. The brake rotors are debris free. the vehicle is 88, 2.6 manual tranny, had autolocking hubs and replaced with warn manual hubs. Wheel bearings are all tight..(recently repacked and tightened). Sound is coming from front, near transfer case. I am wondering if the tranny mount broke and the transfer case and tranny were kinda lopsided on the mount, could this cause binding (just a hypothesis), too cold to check tonight. Any other suggestions. Somebody mentioned needle bearing on the front spindle??? Location and purpose?

Thanks guys
