Hi all

I was trying to remove my rear bumper and the 17mm bolts started spinning in the chassis leg
How can I get the bolts out

Any help please

 

Perhaps prise a screwdriver underneath the shoulder of the bolt and turn?

 

Sounds like the captive nut has come loose from its welds,try the above and if that fails you'll have to grind the heads off and weld some more nuts on the backside of the bumper bar after removal and get some more bolts as well mate.

 

There is a set of tools you can buy called Easy outs. If you drill a hole into the head of the stud, just use on of these and it will turn the screw out for you.

 

Don't think that will help this time fella. The problem is the nut spins on the back along with the bolt when turned.

 

As above gring the bitches off and tack new nuts on. I can't remember the thread pitch but its very fine. I recently did my rear bumper bar (thread somewhere on here but on my phone), but luckily they undid after soaking a few days in advance with Penol. But there were only 4 new ones so went to a local bolts place and got bearish replacements with penny washers

I found the bolts holding the bumper to the arches worse in fairness but my rear arches are starting to corrode as per the law of classics
