Re: Probelms With Removing Wishbones !!!
for the roll bar nut, coat liberally with wd40, and allow to soak.
take an old socket which is too small for the nut, if it was 17mm to begin with, i'd try a 16, or possibly even a 15mm, depending on how bad it is. ideally you want an old metric socket, i can't remember which size. 11/16 is near as dammit 17 mm, so the next size down maybe ?
next, a large hammer. hammer the socket on to the nut, (it may take a fair bit of force !) and try to loosen it, if it works, remove the socket from the nut BEFORE you take the nut off the threads, or you'll likely never use that socket again ! a couple of sideways taps normally do the trick. if it doesn't work ? you may have to consider the hacksaw method !
you could heat the nut, that'll help too, depends if you've access to a heat source ?
you can buy sockets with reverse threads inside them for this purpose, but i suspect the costs would outweigh the usage in this case.
i'd recommend anyone who does their own spannering to invest in a decent socket set, one which drives the nut/bolt on the flats of the hex, rather than the corners. i bought a set years ago, cost about 30 quid, and i've barely had a rounding incident since.
good luck !
