When I got the rear end, I pulled the diff cover, and I noticed that the junk yard drained the fluid....AND that the ring and pinion meshing surfaces had light rust on them. I cleaned them up and put fresh fluid n worked it abit to make sure it spun freely with no hangups.
Now it clicks....I'm gonna drain the fluid n put fresh fluid just incase it knocked some crud loose, but could it just be low on fluid?
Seriously guys I just paid $250 for the rear and $250 in parts. Any info is greatly appreciated,
Make sure it is full of gear oil and you should also put in some Friction Modifier
additive. That may cure the clicking you hear.
Lift the rear tires off the ground and rotate each tire by hand, feeling and listening for any clicks or roughness. The click could be caused by a bad axle bearing.
