Do I need new wheel bearings, or are they already installed?

This assembly arrives loaded — bearings, seals, and internal components are factory-installed and ready to press onto your axle shaft. You're not rebuilding anything.

What hardware do I need to bolt this on?

The knuckle bolts to the upper and lower control arms using factory fasteners. You'll need the original hardware from your vehicle — this assembly does not include suspension bolts or brake caliper hardware.

Can I reuse my old brake pads and rotor on this knuckle?

Yes, your existing brake rotor and caliper hardware will work with this knuckle. Just transfer them over — the mounting surfaces are factory spec.
