Completely rounded the damn nut!! Driveshaft
 

Leave it to me to round a nut the first time I wrench on my Disco. It's a nut on the driveshaft. The top of the pic is the front of the truck. It's on the end of the driveshaft at the front of the truck (FWD input). Pretty sure it had to do with my ****ty wrenches.

It's actually broken loose, but now spinning if I turn the bolt head. But it's still not loosely spinning, it requires a serious grunt to get the bolt to move.

Any ideas? Grrrrrrrrrrrrrr.

Vise-grip on the bad side to hold it and put a wrench on the other side to turn the bolt.

Try what Lipadj46 said. If it doesn't work, use very sharp chisel and break the nut with a hammer, placing chisel on a side of the nut parallel with the bolt axis. Even better, if you have hammer action Bosch drill that can disengage the rotary motion and have a sharp chisel bit, use that.

got it. hit it with PB blaster. squeezed the vice grip 'til i almost blew a rib.

guess this is a good excuse to go buy self locking nuts.

tomorrow is a new day.
