If you soak it in penetrating fluid, you might find that 5mm is enough to grab on with using a set of good quality mole grips? 2005 Td5 90 XS

Is this a bolt that goes into a captive nut that fixed onto the crossmember? if so:-
Option 1 file the remains flat, get a centre punch and punch the exact center of the bolt, drill a 5mm hole into the remains of the bolt. At this point you may be lucky and find that the drilling process may have weakened the bolt enough to unscrew it with some molegrips. If not then drill a bigger hole that matches the internal diameter of the thread of the bolt. Then tap the hole out to clean the existing thread in the captive nut. Option 2 drill the bolt out over size and replace with a bolt over size. (if you can get your fingers in behind the crossmember) Option 3 Drill the bolt out over size to suit a rivnut and fit a rivnut to match the existing. Option 4 replace the chassis (PS i'll take your old one off your hands)  130's have feeling's as well you know |

Climb underneath, clean the threads of the remainder of the Bolt with a wire brush, yes I know its awkward, use lots of penetrating oil, use mole grips on the broken head end to jiggle the remainder in and out, it you will probably be able to remove it. Best of luck. NormanD WE191

clean up the rear as previously suggested, then drill a hole the same size as the bolt in a bit of scrap strip steel, arc weld the strip to the bolt, unscrew using the strip, the heat from the welding will most likely release the bolt from the thread DEFENDER 90 TDCI XS,
I hope everyone is well and your land rovers make you happy |

As above but you could use a nut instead of a metal strip. Remember to disconnect the battery before welding anything on the chassis to protect your electrical equipment. Matt.

Ok so the rear tub mounting bolt. I think if you move the plastic shield in the back of the wheel arch you can get at the back of that bolt. so you can give it a good soaking with release fluid. Ordinary WD-40 or Diesel will do, but proper penetrating oil will be better. Halfords even do a WD-40 branded 'penetrating fluid'. Once you've done that centre punch the middle of the bolt and drill into it, chances are the heat from drilling will be enough to free it off. 5mm is probably not quite enough to get a good grip on it with mole grips without them slipping and damaging paint. |

You could also try the drilling options above using a left hand drill bit. It might just unscrew it at some point - if you are lucky.

You should be able to get at the back of that from the wheel arch.
Heat and vise grips - I don’t use drilling or extractors if I can avoid it. You might be able to heat it and instead of spinning it out the bodywork side bring the clean threads out the back on through the hole if that makes sense? You can also try and shock it with heat then cold water. |

my concern with using heat on that is paintwork damage.
