940 Estate Rear Bumper Removal
Hi All. The rear bumper on my 940 Estate has dropped on one side and rattles a lot. I have the repair kit from Scandix which I'm hoping will solve the problem.
Does anyone know of any guides or videos that show how to remove the rear bumper? The Haynes is not helpful. It feels like it's stuck at the sides near the rear wheel arch. |

You need to undo the side mounting brackets inside the boot under the two side carpet panels. They are on the "outside" of the storage hole in the floor.
You then need to unbolt the impact shock absorbers from the boot floor (easier than removing them from the bumper). IIRC it will look like a 10mm nut on a stud either side. If you have a tow bar and a skirt on the bumper you need to remove the skirt too which is about ten (no doubt rotten and rounded off) 8mm hex headed screws along the length of the bumper and where the mudflap would be. If you have mudflaps you will have to remove those too. |

I didn't realise they did a repair kit.
The repair kit looks like it is to resolve the aluminium steel interface corrosion issue between the steel shock mount and aluminium bumper bar with steel splined press-in inserts. If you ever take off the bumper you will find the bumper and steel in pretty poor condition. You can usually make your own repair plate, the whole thing was a bad design. A layer of etch primer on aluminium usually enough to prevent corrosion. Skandix have a £60 delivery charge now for the UK. Did you pay that or did you get it before brexit? |

My offside corner has dropped and needs a repair, trying to see if I can get a 2nd hand bar first make it good and just swap it over, the kit does look handy but I think have a crack at making something myself over 60 quid delivery

I just made a small steel rectangle with 2 holes in it and welded the bolts on, then feed that through the bumper bar. You just need something to stop the bolts turning.

The bumper is aluminium so suffers from galvanic corrosion when in contact with the steel chassis. My bumper has dropped because the two bolts holding it to the damper on one side have completely detached from the bumper which basically dissolved.
I'll have a go and take some pics for this forum since I can literally find zero resources for this problem. I think I'll have to unclip the plastic bumper cover to do the fix but we'll see. As for the delivery, I'm in France and I ordered it with a bunch of other parts. Delivery was 18 Euros. I agree that 60 quid makes no sense unless you're placing a big order. |

The bumper doesn't touch the chassis, it has an aluminium reinforcement with 4 steel bolts holding it to two steel bumper shock absorbers that are to help absorb an impact and then push the bumper back out afterwards. They rot as you say from galvonic corrosion between the two types of metal around the shock absorber mounting plate.

Okay so I completed the job and took some pictures, I'll write it up into the how to section.
360 beast I'm not sure your last comment was necessary. The impact absorbers (which do not push back out like a shock absorber) are steel and are bolted to the steel chassis so the aluminium crash bar inside the bumper is electrically connected to the steel chassis which is why the galvanic corrosion occurs. Your instructions were helpful but there are also four additional bolts that have to be removed to get the bumper off accessed from underneath outside the car. |

For the how to if you do the write up and post it in the 7/900 series section then people can see it. Then copy the link for it and post in the website support section of the forum asking for it to be moved to the articles section and admin will do it... very long winded way of doing it. |
