Think putting another nyloc nut on will hold it ok,could even grind it down so the nyloc workings engage with the good thread on the existing.Maybe could even get a slim nyloc also if needed.
Bit difficult without seeing the final results,
cram/torque it up and see

ie you didn't here it from me

 

Hahaha thanks!

I really don't see how a new, non welded nut, would affect any alignment. Torqued is torqued right?!

 

PPs
I do mean leave the captive one on,and put another on as well.
Maybe the hole is larger on the captive nut side of the wishbone

 

Maybe. The nut is welded to the subframe itself rather than the wishbone though.

I'm rather confused by the whole idea of it.

If I can't get the bolt out without resorting to a disc cutter then the captive nut will have to come off! Oops!

 

Good luck

 

Either the nut or the bolt (or both) is stripped. Cut the end of the bolt off as close to the nut as possible. If you are lucky it may then just pull out (with a bit of effort/leverage), or come out with a pull and twist? Once out you can see where the damage is.

 

Thanks mate, I'm going to have a look tonight.

If it's the nut that's stripped, is there any complication with removing it and replacing? Or will that, as mentioned, cause alignment issues?

 

I have done this on mine, just used Nyloc Nuts

 

Nice. Just replaced the captive nuts? Or doubled them up?
