Do I need new mounting bolts or hardware to install this?

Use your existing factory bolts and hardware — this assembly mounts at the original hub points. Inspect fasteners before reinstall and replace if damaged or corroded.

Can I reuse the brake rotor and caliper with the new hub?

Yes. The hub is a direct replacement that accepts your existing brake components. Clean the rotor seating surface before installation to ensure even contact.

What tools do I need to swap this in?

Basic hand tools, a jack, and jack stands. You may need a hub removal puller if the old assembly is seized. Refer to your vehicle's service manual for torque specs on the mounting bolts.
