I have a 2001 Ram 1500 2WD 5.9 At a local shop for a tire repair the guy said my front wheel bearings were getting bad and needed replacement. This shop does not have the greatest reputation but it was close for the repair. I really don`t trust this place so how can I inspect the bearings myself and can I replace them myself or do I need special tools. The truck does not have any symptoms and the rest of the steering components have been replaced during the past year.
