Will this work if my bumper cover has sensor holes?

This retainer is a structural clip — it doesn't interact with sensor cutouts or wiring. Your existing bumper cover sensors and holes remain functional. Just make sure the cover itself fits properly over this retainer before fastening.

Do I need to remove the entire bumper to install this?

Not necessarily. You can often access this retainer from behind the wheel well or by partially dropping the bumper cover. Full removal depends on how tight your fitment is — test-fit first to see what clearance you're working with.

What fasteners do I use to bolt this on?

The retainer uses factory bolt holes, but fastener specs and quantities aren't confirmed here. Grab your OEM service manual or check the factory attachment points on your Journey to determine the correct bolt size and torque spec.
