Do I need to transfer any bearings or seals from my old knuckle?

The hub and bearing are pre-installed in this loaded assembly. You're installing the whole unit as-is — no bearing work or transfers needed.

What mounting hardware do I need to bolt this on?

The assembly uses factory mounting points, but confirm fastener sizes and torque specs in your service manual before installation. Bring your existing bolts to the workbench and test-fit first.

Does the rotor come painted or bare?

The rotor ships ready to install — no prep or painting needed out of the box.
