That sounds like a failed bearing. They are not that difficult to change, but it can be time consuming and requires opening the rear axle housing and removing the differential pinion shaft, it lock bolt, and then a C-clip. The rest of the work is done from the wheel flange. There are retainer/cover bolts to be removed after the brake is disassembled. Plan on installing a new outboard seal. The bearing is pressed in place on the axle shaft, but almost any decent auto parts store can pull/press the new bearing. BTW - That leaves out most of the chain parts stores except for maybe Car Craft.
