Rear bumper removal

[mojarra2929]

Any tutorial for rear bumper removal? I only found front bumper´s removal threads.

Thanks

Is it that different???

Maybe you should turn your car around, and pretend you are removing the front bumper...?

Ouch. It is different enough depending on the year. The rub strips attach differently for one thing.

To the OP if you look at it you will see how it comes apart. If you cant, take it to someone.

The oil tank makes it a bit of a challenge.

Going off memory, so dont crucify me if I miss something.

1. Put the back of the car up on jack stands or a lift.
2. Loosen the support arm bolt that holds the bottom of the lower extensions on, no need to take the bolt all the way out yet.
3. Remove the valance (why step 2 is important access to the end valance bolts is difficult if the quarter extension is tight at those support arms that hang down.) edit I guess you don't have to remove the valance, but it makes getting at the 6 bolts that hold the impact bumper overriders on, I think you need to remove those so you can remove the rubber strips to get to the nuts that hold the bumper on.
4. I don't remember if it's easy or not to remove the long rubber strips from the inside back of the bumper at this point or not. If you can, you can then pull it out of the overriders without unbolting the big impact bumpers.
Once, you get the strips off you can see the 4 bolts that hold the bumper to the chassis.
5. unscrew the license plate lights and remove the covers, pull the light out of the impact bumpers and disconnect the wiring harness.
6. feed the wiring harness out through the bumper and tuck it out of the way.
7. Remove the bolts holding the lower quarter extension to the body, remove the bolt that holds the support arm to the lower extension. It's easier to remove the extension with the bellows and bumper in all one piece. The reason is that the studs in the bellows will twist off due to road grime and corrosion. You need to carefully soak the studs with the bumper on a work bench, then pray when you unbolt them that they wont twist off. Same goes for the impact bumper overriders. Those studs are brittle, soak liberally and carefully remove the nuts that hold the overriders on.
8. The passenger side extension is difficult to get to because the oil tank is in the way. I use a really long double extension to get at the metal screws, they should have a hex end. Someone may have replaced them with a Philips metal screw if the car has been apart. Apply force on the extension to take tension off the metal screws when unscrewing them. They will come out easier.
9. Once both rear lower quarter extensions are loose from the car, take some painters tape and line the body above the quarters to prevent scratching. The bellows tend to act like springs and the quarters can move up now scratching the body when you remove the bumper.
10. Now you can take the 4 impact shock nuts all the way off and standing behind the bumper lift it off the studs. It's heavy and easier with two people.

I think another method is unbolting the entire impact shocks off, at the chassis. Again the passenger side access to the nut that holds the impact shock to the body is extremely hard to get to due to the oil tank location.

Here's a diagram for you:

What year is the car? At least on my 88, it's not necessary to remove the muffler....

Yeah, I think when I initially wrote that I was thinking of my specific car. I have a custom smoothie reverse mount bumper with the nuts on the inside. I edited my response.

Just removed mine 2 days ago and was thinking of posting a how-to, but haven't gotten around to it. Took around 2 hours to remove, taking my time at it.



75 911's steps pretty much covers it.

Nothing too complex or difficult, but as mentioned - the body panel & bellow nuts are difficult to access on the oil tank side, but do-able.

Good luck,

Gordo

My car is a 1985.

OK. It's pretty simple. I can post some pictures and tips in the morning if you can wait until then.

The rear bumper is very simple to remove:
1. Probably the toughest part – crawl under the rear of the car with an 8mm wrench and remove the little nuts that hold the accordion trim pieces at either end of the bumper. There are a total of 4 nuts on each end… may be able to get away with just removing the two nearest the bumper. The bolts are built into the accordion, so you have to pull/push them free of the bumper.
2. The rubber protective strips have little round covers/plugs for some Phillips-head screws -these covers are about ¼ in diameter and just pull out.
3. Remove the two Phillips-head screws and pull back the rubber protective strips. They should slide out from under the Bumperette (likely a little different on euro bumperettes)… you don’t actually have to remove the screws closest to the wheels – you just need to remove the ones near the bumperette so you can get access to the bumper nuts underneath the strip.
4. Now that you have access to two nuts on each side (4 total). Remove them and your bumper will slide off. However, your license plate lights (in the bumperettes) will still be connected. Figure out how to disconnect those – it’s pretty simple.
That’s it… bumper is off.

That's it! I also remove the bumperettes to make it easier to disconnect the lights.

no need to the licence plate lights wires just slide out...and pretty easy to guide them back...

75 911S is correct. Don't mess with the bellows/bellows nut on the car. See his point seven above.

"7. Remove the bolts holding the lower quarter extension to the body, remove the bolt that holds the support arm to the lower extension. It's easier to remove the extension with the bellows and bumper in all one piece."

Yes, Detach the side skirt lower bolts, then the side skirt to fenders sheet metal screws.
Then the main rear bumper four big nuts on fixed bolts
Pull back bumper and at the same time shove down the side skirts.
Take it off in one piece with or without the bumperettes.

Leave those bellows accordions alone while on the car...unless you like misery.
Pretend its an IROC one piece.
