Rear bumper advice please
 
Hi all,

Removed the rear bumper from my ur yesterday ready for a bit of a tidy up.

Inevitably a couple of fixings snapped :grr:- where the bumper is fixed in the rear wheelarch (M5 cap head screws that fix into a threaded insert - part no. N 030 355 1).

I know the inserts are available online, does anyone have any advice on removing the old ones? Just a matter of drilling out the remains of the bolt and pulling the old insert out?

Any knowledge out there would be greatly appreciated, thanks in advance. :tup::tup:

I used a Dremel with a mini cut off disc and chopped it off from the inside lip of the wing.

There was very little good metal left on my Ur that I had to weld in a new metal strip, drilled holes to suit the inserts and new screw fixings.

Thanks guys.
I need to have another look (it was getting dark when I finished on Saturday) but I didn't see how I could get at the threaded fixings, they seemed to be enclosed within the lower rear arch.

They will be riv-nut type fixings, if you just drill them out you may end up with a hole that's too big, do you have a Dremel ? if so just carefuly take the front face off then remove from behind, that way you can use the existing hole for the replacement riv-nut (or captive nut if you prefer) and it will be as good as the old one's were when they were new.

Thanks mate, all kind of makes sense.
Obviously need to get a good look in decent light. :tup:

Let me know how you get on.
Just a though, you could carefully drill whats left of the bolt out and then run a tap through the existing fixings to clean the threads up, that could be an easier way to sort it perhaps.

That was going to be my 1st approach and then see if I need to pull the inserts, iirc I have 4 to do :(

Cheers, will let you know how I get on. Might be a couple of weeks before I get to it though.
