Do I need new bolts or fasteners to install this?

The assembly uses factory mounting points. Check your existing hardware when you pull the old hub — if the bolts spin freely or threads are stripped, grab new ones. Most installs reuse factory hardware.

What tools do I need to get this on?

You'll need a socket set, a breaker bar for the axle nut, and a jack with stands. A wheel puller or bearing splitter speeds up removal of the old unit if it's seized. Refer to your vehicle's service manual for torque specs and removal sequence.

Can I reuse the rotor or do I need a new one?

The rotor is separate from this assembly. If your rotor is worn, scored, or below minimum thickness, replace it. A new rotor and fresh pads are often installed at the same time for best braking performance.
