I shafted three of those dudes. Switch to Detroit Locker, problem solved.

 

Those things are dead reliable! The old ones were just plain mean.

 

Isn't that the PowerLoc diff?

 

Nope, no clutches or spiders. I kept breaking spider gears and shafts to I went with the locker. Hazards of a manual transmission with a reprobate behind the wheel!

 

I had 52 binder boom truck I used heavily in the woods. I had to keep a deep supply of axles and rear gear sets on hand. Basically when you chain it, put enough load on it to lift the front wheels on the ground, then dump the clutch in granny, something's got to give. Usually it was the load, but sometimes........

 

well I got all clutches, bearings and ring an pionion replaced shimmed ,over and over. would never do it without case spreader.
