Basically any owner of a GM car, truck or SUV with FWD in the E-Body or W-Body chassis family should find this guide helpful.

My brother and I had previously replaced a front wheel bearing hub assembly on my Pontiac Grand Prix GTP about a year ago. We used a "Made In China" DynaPak brand hub that immediately caused a loud popping noise during low speed parking maneuvers. Recently the other GM OEM wheel hub began to wear out and cause a loud drone inside the car from the friction of the worn metal bearing. The sound of a wheel bearing that needs to be replaced is similar to the road noise created by low quality tires but much louder. We researched the different wheel bearing brands online and read consumer reviews. It seemed that most people disliked the Chinese made replacement parts due to their lower quality.

We removed both of the front Torque Star wheels on my 2001 Pontiac Grand Prix GTP and also took out the spare tire from the trunk. Removal of the front axle nut on GM E-Body and W-Body cars requires a 36mm socket. The axle nut socket wouldn't fit through the hole in my wheel where the "Pontiac" center cap pops in so we had to use the spare tire instead. Lowering the spare tire in contact with the garage floor kept the wheel from spinning while removing the axle nut using a breaker bar. If you own an electric or air powered impact wrench, it makes this part of the procedure much easier.

It's also possible to remove the axle nut without using the spare tire and lowering the car. You can place a large screwdriver in one of the brake rotor's vanes and it will hold the wheel hub in place against the brake caliper while you remove the axle nut.
