2002 Chevy Cavalier front wheel hubs

It is a much better idea to get a car repair manual (use link in this thread) or get a Haynes manual.
But generally:

Raise car and put on stands.
Remove wheel and any plastic shield.
Remove caliper and bracket (hang caliper out of way), remove rotor.
Disconnect ball joints from knuckle.
Remove outer tie rod.
Remove axle nut (if you do not have an impact wrench, loosen the bolt first before raising car).
Remove axle.
Hub is bolted to knuckle with (usually) 3 bolts and there is a larger hole in the hub which you align to get access to hub bolt. The hub bolt can be a hex or a Torx. If Torx, rent an electric imact wrench but spray bolts with PB blaster and let set overnight.
Remove bolts and hub, install new hub and bolts, torque to specs.

While axle is out, replace axle seal in trans. After you are done check and fill as necessary the trans fluid.
