Just a quick update. Pulled the driveshaft checked ujoints again. Small resistance but. Ow grinding found. Greased and reinstalled. While in neutral, rotating driveshaft back and forth I hear a clanking in the tail shaft section. I know the rear springs are worn so I put c clamps on the leafs to simulate load in the car while driving, but that didn't help( cars is off ground). I hear the clunk noise in the car on passenger side, and sometimes while shifting from drive to reverse.
Something else I just discovered, while rotating the passenger side wheel back and forth I get some play before the drive will turn and hear gears meshing? Drivers side is not so pronounced. Is this normal? Trans is in neutral
