Ford Ranger 2001 4.0 124000 miles
Driving home, heard a rattling like a chain dragging the ground. Pulled over didnt find anything. Got home jacked truc up. Spun passenger wheel nothing in the wheel. Took wheel off turned hub. Sound coming fro drive shaft pumpin area. Pulled plug. Low rearend grease. Put a qt in. Test drive. Rate still there. It's almost sounds like a bearing. But no noise from wheel when hand spun
Hard to believe that the rear leaf spring grommets would be the problem. Any input would help.
