Add some heat to the axle about where the cross pins would be. The heat will draw in the penetrating oil. Also a few good hits on the axle will knock the rust loose. One side of mine came right out, I beat the heck out of the other side. With out fenders to whack, you sould be able to drive the pins right out. Use the biggest punch or drift that will fit in the hole, go buy a piece of steel rod 3/4" or bigger and make you a long handled "T" to hold and hit on. It works a lot better if you have some one hold the driver while you swing the mallet. Wear safety glasses, king pins tend send out very sharp projectiles! Joe
