De-Code Rear Axle - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Ironhorse** · 01-30-2008, 09:05 AM

Trying to de-code the rear axle on what I "think" is an '80 GMC 3/4 ton 4x4 LB. Frame with running gear, 4 speed trans., transfer case and what I know is not the original cab. Has the large hubs on rear axle with the following:

K JU G 3 081 stamped into the upper right hand rear axle tube. Fourteen bolts on the rear housing.

Not really familiar with the "square body" trucks and my "red book" only covers '46-'72 years. Anyone help with a de-code? No sheet metal from cab vin to help pin down the year. Tried doing a search but only came up with RPO codes but no stamping codes.
