spindle nut removal?
#23
You CAN NOT use a plumbers torch to heat these things. You need a real oxygen/acetylene torch to put as much heat into the nut as you can in as short a period of time as possible. If you try to heat the nut with a little hand held propane or even map gas torch, you'll ruin things for sure because you are going to lose so much heat to conduction that it'll take forever to heat up the nut properly.
Thermal shock is what you are after, not just the expanding of the nut. Thermal shock is what will break loose the nut and allow you to remove it. Rapid heating coupled with rapid cooling will loosen things up nicely!

since the bearing is bad heat the mother up and spray it with pb blaster.
ive removed frozen kingpins on class 8 trucks with heat and pb blaster. got the steering knuckle red hot and poured pb blaster into the top portion of the kingpin. smoked like hell and slowly the blaster and the dried grease and rust oozed out and the kingpin almost fell out (slight nudging with my air chisel)
but you get the point. heat and blaster then bang on it with your impact.
if you have an impact driver use a 1/2 ext and hit the mother while its hot and it should turn a bit
