Do I need new hardware to mount this assembly?

Mounting hardware is not confirmed with this assembly. Use your original fasteners during installation if they're in good condition, or source replacements to match your factory specs before you begin.

Will this work on either side of the vehicle?

Window motor and regulator assemblies are typically side-specific. Confirm whether you need driver-side or passenger-side before ordering to avoid a mismatch.

What if the window doesn't operate smoothly after install?

Check that all fasteners are tight and the regulator tracks are free of debris. If binding persists, the assembly may have been damaged in transit—contact support with photos of the install for next steps.
