can someone decode this axle code? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey all, I was putting my new tires on my truck & while I was there, I looked for an axle code. On the front of the axle, on the passenger side it has stamped:

HA Q3 17 K

What does this mean? I turned my driveshaft & my tires turned about 3.25-3.5 times.... Thanks for looking at my post!

Joesjunk, or?
Does that axle tube code actually have anything to do with the original gearing?

Mine is HB 10 09 W Does that mean anything?
