Do I need new control arm bolts when I install this?

Control arm bolts should be inspected and replaced if worn or damaged. Your service manual will specify torque specs and whether new fasteners are recommended for reassembly.

Is the brake dust shield included, or do I transfer mine from the old knuckle?

Transfer your existing dust shield from the old knuckle to the new assembly. The loaded unit does not include a shield — it's a reusable part that moves with the knuckle.

What about the brake caliper and rotor — do those come with this?

This is the knuckle and hub only. Brake pads, rotors, and calipers are separate items you'll source and install independently.
