I'm replacing my front & rear bumpers with new OEM parts. The originals were on there and have not been off the car ever. The car has lived in CA & TX its whole life, so there is minor corrosion on the hardware. Documenting what I've learned here for folks, starting with the rear bumper:
Will update this thread with any tips on the front
- Spray the nuts with penetrating oil, I did this 2x over a couple days. When you crawl under the car you can see all the hardware from the inside. There are:
- 6x chrome tipped bolts that thread into 17mm nuts from the top down
- 6x bolts that thread into 17mm nuts from the bottom up
- 3x 12mm nuts per end cap that hold the end caps on
- Remove the end caps - I should have done this to start, since it allows you easier access to the outer bolts
- Remove the 4x (2x on each side) 17mm bolts that are on the bottom of the bumper, closest to the end caps. I used an impact wrench for this. I've added a picture that points these out with red arrows.
- Once the bolts in #3 are out, you can thread a socket extension through those holes.
- First, put the extension up through the bottom holes, then while it's already in the bumper, put the 17mm socket on. Pic attached.
- Used an impact wrench for this too.
- 2x of the chrome bolts came out just fine but the other two just started spinning. The trick I used to get those out is to attach a set of vice-grip style pliers to the top of the chromed bolt, have someone else hold that, and then loosen the nut by hand from underneath. Took a lot of strength & went slowly but got them all out.
- The chromed bolts in the middle at the top are impossible to reach. The bumper is bolted with 4x bolts (2x bottom, 2x top chromed) to a metal mounting plate that then mounts to the frame above where the hitch is. This mounting plate is bolted to the frame with 2x 17mm bolts.
- Lower the spare
- Unbolt the 2x bolts, have someone lean against the bumper so it doesn't fall off
