Not sure wheel bearings are considered lifetime parts. They are shielded bearings so are non-regreaseable. I have changed several on my 9000's. The most recent being my wife's 97 CSE with around 200K on it. My 96 Aero will probably need the left front when I change the axle soon. Also a little over 200K. The left front brakes are dragging going around left hand corners. It quiets down once running straight. That's a good sign the wheel bearing is suspect. When I changed the axle on my wife's car, the bearing was in really bad shape. The balls were worn undersize badly. You won't notice how bad it is until you push the axle out of the hub. One thing that can damage the hub is beating the axle spline out of the hub. I have a axle puller (really a pusher) that attaches with the lug bolts and pushes the axle out. I think it cost $40 but has made changing axles much easier, quicker, safer and causes less collateral damage. I bought four SKF/Timken/CR hubs years ago and still have a couple. I also have a cheap Chinese one that I won't install. The first time I had a wheel bearing fail was one that was changed by a Sear's Automotive shop after they boogered up the factory one driving the lugs in with an impact w/o starting by hand first. The cheap hub they installed lasted a short time. They replaced it with an SKF and I never touched it again.
