Correct 10.5" FF Axle Nut Socket

[andy396]

Can anyone tell me the the correct tool for tightening the axle nut on a 1995 GM 10.5" Full Floating rear axle in my SRW K3500? The GM tool number is J-2222-C. I have KD-2770, but it has square lugs, not rounded ones. I'll probably end up just grinding on what I've got, but I'd love to know what the correct tool is. There's so many different ones out there it's ridiculous.

GM - "Hey, if we tweak the part so the old tool doesn't fit, everybody will magically stop working on their own cars and start bringing them into the dealership for service!"

Aftermarket, five minutes later - "New tool available!" ...and GM wonders why they had to file for bankruptcy.

The GM tool number is J-2222-C.

There's your answer. I bought mine used, on eBay.

Mine uses a pair of roll-pins to engage the rounded slots in the nut.

That’s after about 45 minutes of grinding and filing. I was in a pinch to get the job done.

Whatever works.
