Do these bolt straight to my Pacifica, or do I need special tools?

They mount at factory rotor and suspension points — no drilling or fabrication required. A basic socket set and jack will get you through the job. Have the wheel fully supported on a stand before you start.

Can I reuse my old rotor, or do I need to buy new ones?

The assembly includes the rotor mounting surface. If your existing rotors are worn, scored, or undersized, replace them. If they're in good shape and within thickness spec, they'll work. Check thickness before final assembly.

What if the bearing feels loose after installation?

These are pre-sealed and non-adjustable. Tightness comes from the axle nut and proper torque spec — check your service manual for the correct value. Over- or under-tightening will cause play or binding. Torque it once and move on.
