How do you know if the rear wheel bearings are bad on a 2002 Mercury Mountaineer and is this something a normal person can repair?

Answer 1

I have replaced one front and both rear wheel bearings on my '02 mountaineer. When they go bad, you'll typically hear a humming or rubbing sound coming from the bearing while the vehicle is in motion. Significant disassembly is required to get to the bearing and the old bearing must be pressed out with a hydraulic press. the new bearing must be pressed in in similar fashion. It's a tough job for your avg guy whose mechanical experience is limited to basic maintenance and who may not have access to a hydraulic press.
