Fighting king pins.... After stripping the 7/8 hex, then running out of gas with the torch and uga dug power on the breaker bar I used a you tube method of welding a piece of steel to the king pin. It didn't say no when I hit it with the 10lbs sledge (my purse)
Had to borrow a friend's BA torque wrench to get the new king pins to 600 ft lbs!!! To say the least I was a little intimateded but it went smooth with the 5ft handle.
