Do I need to reuse my old brake rotor and caliper?

Yes. This knuckle assembly includes the hub and bearing—bring your existing rotor, caliper, and brake pads with you. The new knuckle bolts straight in and accepts your current brake hardware.

Will my alignment change after installing this?

No. This is an OEM-spec knuckle, so factory geometry and attachment points are identical. Your suspension geometry stays the same—get a post-install alignment check as good practice after any suspension work.

What tools do I need to swap this in?

Basic hand tools and a jack. You'll need to disconnect the sway bar link, tie rod end, and control arm ball joint, then unbolt the old knuckle and bolt the new one in place. Refer to your service manual for torque specs and procedure order.
