I'v owned my 2000 grand prix se for about a year now and have had to replace the wheel bearings three times. This last time the shop I go to called up the rep from the company that made the wheel bearings and got him to come to their shop and look at them. The rep said that when gm designed the car they made it with the wrong size bearings and that there destine to where out every 6 to 9 months. I was just wondering if any one had run into this problem, or if there is a part update to fix this problem?
