Will this bolt straight into my vehicle without modification?

Yes. This assembly uses factory mounting points—no drilling, welding, or frame work needed. Unbolt the old unit and swap it in place.

Do I need to remove the door panel to install this?

Yes. Door panel removal is required for access. It's a do-it-yourself job if you're comfortable working inside a door cavity; if not, a shop can knock it out quickly.

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

Check that all fasteners are seated and secure. If binding persists, confirm the regulator track is aligned and free of debris before applying any force.
