How do you remove and replace front wheel bearings on a 1996 Chevy Blazer 4x4?

you cannot replace the wheel bearings by themselves in a 4x4. they designed the hubs to have wheel bearings inside them. you must replace the whole hub assembly to get new wheel bearings. should run from 50-100 dollars a piece from a parts store, and about twice that at a dealer.

You need a 36mm socket and a breaker bar . Take the spline nut off the end of the cv shaft. I suggest doing this with the wheel still on the ground. Then jack the truck up. Remove the caliper and rotor, take out the three bolts holding in the hub. Be careful around the abs sensor. They are expensive. Installation is the reverse of removal. Torqe the spline nut to approx 180 ft.lbs.
