Do I need to transfer my wheel bearing or hub to this assembly?

Test-fit the assembly against your existing hub and bearing setup before committing. Some buyers retain their original components; others source them separately. Verify fitment with your specific brake hardware and rotor configuration.

What fasteners do I need to mount this to the control arms and strut?

You'll need bolts for the upper and lower control arm attachment points and the strut connection. Refer to your vehicle's service manual for torque specs and fastener sizes — hardware is not included with the assembly.

Does this come with brake components already installed?

The backing plate is integrated and ready to accept brake hardware. Caliper brackets, pads, and rotors are not included — source those separately based on your brake system specifications.
