I have my car in with the Opel Dealer twice and twice they can not determine which wheel bearing is shot.
I think its one of the rears as the grinding metal noise is coming from the back, but if you sit in the drivers seat it sounds like its the right rear, and if you seat in the passenger seat it sounds like its the left rear.
Definitely not the front, i locked the steering wheel both ways and not squeeling noises.
I was thinking about taking it down the motorway some night and go left to right, right to left and wait to hear which side the noise is coming from when the weight is put on the wheel.
Does anyone know how i may find out, any hints or tricks.
