Do I need new hardware to install this, or can I reuse the old bolts?

Check your old assembly before install. If the fasteners are in good shape with no stripping or corrosion, reuse them. If they're corroded or loose, grab fresh hardware from a parts store—standard wheel hub bolts are cheap insurance.

Will this fix my ABS light or wheel speed sensor error?

If your ABS light is on because the bearing is worn (causing a bad tone ring signal), this assembly should resolve it. If the issue is elsewhere in the ABS module or wiring, the light will persist—get a scan before assuming the hub is the culprit.

Can I install this myself with basic hand tools?

You'll need a jack, jack stands, socket set, and a torque wrench. The brake caliper comes off first, then the rotor, then the hub fasteners. Straightforward, but take your time—wheel bearings aren't forgiving if you cross-thread or over-tighten.
