Popping in my rear end

[chevymaher]

On jack stands drive shaft out. Check universals. Check yoke/pinion play. Turn the wheels and listen.
Check axle bearings.

Is it a posi? If it is may need the Fluid changed and new posi additive. They chatter when the additive wears out.

If it is a one wheel peel. Turn the wheels in opposite directions and listen for a broken chipped spider gear.
