I was given a list of recommended repairs, including my front wheel bearings at an estimate of over $600 each (including parts and labor). I hadn't indicated any issues with the wheels so I brought my car to seek a second opinion from a friend's mechanic with a private shop who said the wheels were in great shape and not loose at all. I initially went in to make sure my car was safe to drive to the east coast because I'm moving in a few weeks. I'd like to give them the benefit of the doubt since everyone I've met there is friendly and helpful but I don't know what to make of this diagnosis.
