Hi Scotty so I'm saving trouble with my Ford ranger 4x4 getting my rear right tire to spin what should I check next my rear differential is good I have all new hardware in the drums I don't know Wat the problem could be thanks n have a good day

make sure drums are not too tight, try adjusting the auto adjuster in a bit. If it was bearings or axle, it would bind with drum off, so check that first
