Do I need to transfer my brake rotor and caliper?

The assembly comes loaded with brake hardware, so transfers depend on your specific service. If you're replacing a damaged knuckle, inspect the rotor and caliper on removal—transfer them only if they're within spec and not due for replacement.

What suspension fasteners and hardware do I need to bring?

The knuckle bolts to factory suspension points on your Sienna. You'll need the strut mounting hardware and control arm fasteners from your vehicle's service manual—these are not included. Have your manual ready before you start.

Is this assembly ready to install straight from the box?

Yes, it's a complete loaded unit. You won't need to rebuild, press, or machine anything. Mount it to your vehicle's factory suspension points using OEM or equivalent fasteners and torque specs from your service manual.
