Currently trying to remove my rear bumper on my CLS63 AMG W218 so I can fit a Carbon diffuser, all is going well apart from the 2 bolts which hold the main section to the chassis.

According to a YouTube video they are 10mm bits which is fine, however on mine they have a long stem pointing upwards so I am unable to attach a socket. ive tried prising it downwards to no avail, nor is there enough space to get some pilers in.

Any ideas?


And from above:


The end of the long pin is welded to the chassis, and the other side of the bolt is the bumper itself...!

Isn’t the pin just for help to locate the fixing and make sure the fitting is level?

You should be able to get a 10mm ring spanner over it?

Thanks for replies, however the pin is attached to the chassis from both ends. makes no sense?

You're missing something somewhere. I can't tell from the photos what the problem is, but I suspect you're not seeing something right.

Does that shaft go straight through and the bolt you can see is there to adjust how far the panel can be pulled/pushed along the shaft based on a tightening nut the other side of the panel? Something like that anyways.

Are you sure it's welded on the non nut and washer end,
Could it be painted sealant?
As you say, loosening the nut and washer isn't going to achieve much if the shaft is welded to the chassis.

Is it like this: https://youtu.be/nkaGB7cB18w?t=123

The video says a long 10mm socket or a pipe wrench, but, I wonder if your car has had a bump and bent them up.

I assume those shafts attached to the nut/screw we can see would be there to aid the fitment of the bumper assmebly in the factory, to help guide everything in to place accurately.

In which case they can't be attached at the other end.

OP, you need to have a better look! smile

I'm intrigued as to the outcome now. smile

Its so long because it acts as a guide to aid fitting the bumper, yes you need to use a deep socket on it and it should be aligned with the cut-out on the inner skin. If you look closely at that photo, it looks as if the panel is distorted so the stud is at an odd angle, just use a pair of pliers or a length of tube to lever it straight and then use a deep socket.
Or try this:
