I am in the middle of this project to replace the driver's side rear wheel bearing. I used a standard 6" bearing puller to extract the hub from the bearing and axel spline. Naturally, it came off while separating the sealed bearing, leaving the inner bearing race attached to the hub. A quick trip to the machine shop removed the race. Now I have the new sealed bearing and I am torn regarding installation. 1. Do I just bolt up the new bearing to the hub mount on the car with the 4 torx bolts, then "slam" the hub into the bearing and onto the axel spline (of course using a good sledge hammer and some discretion), OR 2. Do I need to have the new bearing pressed on to the hub shaft and then "slam" the shaft on to the spline before finally bolting the bearing assembly in place? So far, the machine shop is in favor of pressing the bearing on to the hub shaft. It looks easier to bolt the new bearing assembly on the arm/brake/wheel bracket, and then slide the hub shaft through it, but is this the way it is done? The machine shop is worried I will end up detaching the inside bearing race using this method.
