Chris mentioned that there was wheel bearing noise coming from the front end during the Road-Tour last fall..... Had some time so I figured I would take a look at replacing them....... Then I realized that when I built the car 15 years ago I put a stock GM front disc assy on the car..... Hummm!!!.... As long as we are updating everything we might as well give the Hydra-Boost system something to work with...... LOL....
