Sturart,

I found a tool used to take out a retaining nut on GM four wheel drive
hubs in the Snap On catalog. It doesn't give the diameter, but it does
have six lugs and is 3.75 " long. So from the picture I could imagine
it being about 2" in diameter. SO pt# S6109A if you want to flag down
your friendly local dealer and see it he has one on his truck. Or even
easier, just wander down to the GM truck dealer nearest you and see if
they have one there.

Best of luck.

other places. Anyone know of a source?
