Front Axle Special Tool # 8000.70139

[WetDuc]

Yea, I got one.  It's real cheap, but isn't completely necessary by any means.
You can't just tighten down the axle nut because the axle will spin on the RH side.  The tool keeps it from spinning.  Once the axle is tight, it's just doing the pinch bolts and brakes then done.
