Anyone ever replaced rear wheel bearings?

Just wondering if anyone ever replaced rear wheel bearings? I wonder if it could lead to vibration and loping.

I'm not sure mine are bad but I get an out of round feeling on one of the rear tires when driving at really slow speeds. Kind of an up and down.

Tire store said the tire was pretty close to perfect, so I am guessing it is something else (Maybe it is a bad knob sticking up. Mud tires).I occasionally feel it it when braking also but the rear drums seem fine too.

definately does NOT sound like a wheel bearing. tires could balance out ok, and still cause the prob.
try rotating the tire to the front opposite side just for a test drive and see if that helps, and if not then i would start looking at a sticking shoe or drum out of round etc.
with a little patience and some rearranging of parts you should be able to narrow it down pretty quick

Thanks. I know the rear bearings have never been replaced and I wondered if they would be contributing to the problem.

Go to the tire shop and have the tire balanced by using the adapter that bolts the lug holes to the machine hub. This will give a balance just as the tire is mounted to the truck, not just the center of the rim. You could have a bent wheel. What kind of tires? Some swampers will hop around evrywhere and still show a close balance on the machine.
