1. Jack the vehicle up and support with proper jack stands.
2. Remove the wheel and tire.
3. Have a helper hold the brake pedal while you loosen the Axle Shaft Nut. This usually requires a large socket (30mm or larger) and impact wrench.
4. Remove the brake caliper and brake rotor. Use string or a plastic tie to hang the caliper up and out of the way. DO NOT allow the caliper to hang by its own brake hose.
5. Unplug ABS sensor (if applicable)
6. Unbolt the hub flange. The hub may come free from the axle shaft easily, if not, use a gear puller or similar tool that pulls on the hub while pushing on the axle shaft. DO NOT try to drive the axle out with a hammer, this could ruin your axle CV joints.
7. Reverse order to install.
We were able to do a removal and replace on a GM car in about 45 minutes.
NOTE: If you are unsure which of your hubs is bad listen while you turn the wheel slightly. If you hear the noise while you curve to the right and it goes away when curving to the left your RIGHT hand or passenger side hub is going bad and vice versa. In our experience replacing both hubs is best even if only one is bad. Most likely the other side is gong to go bad soon. Original Equipment (OE) hubs usually last to just over 100,000 miles.
