These well worn spindles come out of I think an Alis Chamers back hoe.
The steering ran on needle bearings that had worn out and trashed the king pin for a better word. Building up the shaft would have left it too soft for a needle bearing so we're going to use brass bushings. The lower bearing surface was 2 inch, it cleaned up at 1.94, the upper bearing surface had to be built up to clear the spline for the steering arm, the spline is worn too.
Cleaned up and sacrificial brass shim stock in place to protect the spline.
Built up with the mig using .035 wire.
The bottom of the king pin had a centre hole and I wrapped the threads with brass shim stock to protect them from the jaws.
The spindle coming around was the full of the lathe swing, actually had to loosen the DRO readout and shim it back to clear.
All cleaned up now bushings and tapered pins to tighten up the steering arm splines.

Free advice is worth exactly what you payed for it.
