Hi Dave, my bearing went on the way to work just before Christmas. I was told to stop driving immediately. However I have since heard that although the bearing makes a terrific noise you can continue to use the car but the noise gets even worse. Not sure how true this is but it may be worth checking with Vauxhall if you really need to use it. I flat bedded mine to the garage. I got it back within a week but now I have a wind down noise on de-accelerating - makes me feel I am driving a milk float! I will be checking it out with the dealer when it goes in for its service but I guess it may well be down to the change of bearing from plastic to metal. I'd be grateful if you would let us know how you get on.
