My cruiser has developed a driveline whine while "ON" the gas. 96 cruiser with lockers. Stock gears. diffs never opened.
-I have taken off the rear DS and it is still there. with cdl locked.
-New knuckle rebuild. Noise started before knuckle rebuild. been getting louder with time.----
-Output flange on tcase feels very tight with no slop in any direction.
-Front pinion doesn't have any slop either.
-whine/humm starts at EXACTLY 20mph everytime
-Whine/humm goes away completely when off gas
-Whine/humm gets less noticable at higher speeds but is still there
-Brand new DC front shaft
-New diff fluid. Old was pretty new but just changed. No metal in fluid at all.
-Noise is the same stone cold or after driving for awhile
I am thinking pinion bearing but not sure since its tight.
Any help would be great. Thanks
