Do I need to replace both sides at the same time?

Not required, but recommended. Replacing both hubs ensures even wear patterns and consistent handling feel. If only one side is noisy or failing, the other is likely close behind—replacing them as a pair saves a second teardown later.

What tools and hardware do I need to install this?

You'll need basic hand tools, a socket set, and a brake rotor removal tool or pulley puller. The kit itself does not include specialty fasteners—use the hardware already on your vehicle. Have your service manual on hand for torque specs and reassembly sequence.

Can I reuse the old brake rotor and caliper?

Yes, in most cases. Once the hub is out, inspect the rotor for damage or excessive wear. If it's serviceable, reinstall it on the new hub. The caliper stays attached to the suspension and does not need removal unless you're servicing brakes at the same time.
