Machine shops can press them in and out. The second type is the 2nd generation in which the hub and bearing are replaced as an assembly which is bolted into the knuckle. These are usually easier to replace. Look for three or four bolts on the back side of the knuckle to find out which type you have. Gerard [Reply]   [No Email]

Make sure you torque the hub nut to specs and not just "tight". The torque sets the preload. A hefty punch put in the cooling fins of the rotor works great. Post back if you need any more help.

Most shops dealing with front ends and wheels that I have dealt with will give you a "Sir, I need you to come and look at this" then show you why you need to have some extra work done. Of course I'm always there when they are working on it. I don't just drop off a car and go home. [Reply]  [No Email]
