1978 RX7 GS I have to remove the left rear wheel. The three lugs came out easy, the fourth came apart. The chrome head came loose and rotated freely. We removed the head with a torch and a cold chisel, then got on the remaining stub with a broken stud remover. No luck .it will not let loose, all it did was reduce the diameteer of the stub,and has done so to three different sizes. still wont budge. any and all ideas practical and way out are welcome. I am out of airspeed , altitude and ideas. Bob

 

Drill a small hole thru the center of the stud. Use quality drill bits, then try to get a stud remover crammed into the hole.

If that don't work, just keep increasing the diameter of the hole until the stud collapses. I've done this method alot but it's a last resort as you don't want to drill the threads in the axle. hub. Putting the drill in reverse will sometimes unthread the stuck bolt/stud real nicely, once the bit catches.

Keep using a torch to heat the hub, hopefully it'll expand and help the stud loosen.

Also http://www.kanolabs.com/ works great to loosen it.

 

can you get a pair of vice grips on the stud? if you can clamp them down and try heating up the hub. go back and forth and it may come loose! this method has worked for me in similar situations

 

studs are cheap. mazdatrix.com

 

Weld a nut on the end of the stud. Let cool grab socket remove.

 

Bob, this is probably the best option if you have access to a welder. Otherwise, maybe a tire shop can get it off for you. This is probably not a new issue for someone like that, so they have have a few tricks up their sleeve (not to mention air tools).

Good luck...
