Does this kit include the bolts and hardware to mount it?

The hub assembly itself is included with its sensor harness. Check your vehicle's service manual for the correct bolt specifications and torque specs—your OEM fasteners can typically be reused if they're still in good condition.

Do I need to do anything special before installing this?

Clean the mounting surface on the spindle and hub carrier to remove any corrosion or debris. The assembly is ready to bolt on—no painting or prep work needed.

Will the ABS sensor work right away after installation?

Yes, the sensor is built into the assembly and will function once bolted in place and the harness is connected. If your ABS warning light stays on after install, the sensor may need to be repositioned slightly—consult your service manual for proper clearance specs.
