You need to replace the rear wheel hub - bearing and speed sensor inclusive
change your wheel bearing!!
They stopped making Sunbirds in 1994, you have a Sunfire
It will cost approximately $150 to change the front wheel bearing on your 2000 Ford Explorer. The wheel bearing will cost approximately $30 and require two hours of labor to install.
You can change the front wheel bearings on your 2000 Buick Regal without replacing the entire hub assembly. You can change each individual wheel bearing, if you choose.
Remove the tire and wheel. Remove the axle end cap. Remove the wheel bearing retaining nut. Remove the wheel bearing seal. Remove the wheel bearing. Reverse the process to install the new wheel bearing.

Buy the part on eBay and take to a mechanic for replacement of assembly
I'm not sure how to change them, but you nay want to call your local Ford dealership as the 2000 Focuses had recalls several years in a row for the wheel bearings. You may be able to get them replaced for free.
how do i find out if i have ABS on my front wheel bearing , on my 2000 dodge Dakota quad cab 2 wheel drive
Remove wheel then remove the big nut that holds the axle to the hub. Remove the brake caliper and rotor, through the hole in the face of the hub(where the wheel studs are) remove bolts that hold the hub and bearing to the steering knuckle. Tap hub and bearing assy from knuckle. The hub and bearing is one part.
