I have been noticing a popping noise that feels like it is coming from the rear end. I only notice it at speeds slower then 10mph. It only does it ever so often, not a constant pop. Kinda feels like a bad tooth on a gear. Anyone experience this problem, please help.

 

whats up. You might need to add more diff lube. That happened in my boss's dodge and that fixed it right away

 

Does it have a locker? If so maybe the clutches aren't slipping the way they are supposed to. Check and be sure the fluid level is full like greeny said first.
