Do I need new wheel bearings, or are they included?

The bearing races are integrated into the knuckle assembly itself. Whether you need to replace the actual bearing rollers depends on wear—inspect yours before install to decide if a fresh bearing is worth doing while you're in there.

Will this work with my existing brake components?

This knuckle includes the OEM brake mounting surface, so your existing caliper bracket and rotor setup bolt on directly. No adapter plates or modifications needed.

What tools do I need to swap this in?

You'll need a jack, jack stands, basic socket set, and a bearing press or access to one if the old bearing is stuck. A ball joint separator and wheel hub puller are also common—refer to your service manual for the exact torque specs and procedure on your model year.
