Rear axle offset question
I was looking at the axle on my old 71 big block 157 in wheel base DRW C30 comparing it to a standard 3/4 ton axle. What is the reason the one ton center section isnt centered on axle meaning one axle side is longer than the other. Looking at the 3/4 ton the center section is centered on the assembly like all 3/4 and half ton Chevy trucks I have looked at.

Re: Rear axle offset question
The driveshaft and pinion gear of most differentials are centered.. This puts the ring gear offset to one side, making one axle longer than the other.. I can't see your C/10 from here but I can see my '71.. It's not centered...

Re: Rear axle offset question
I just assumed on the 3/4 ton the axles were the same on each side. I’ve never taken a rear end apart, beyond my capability. After reading your post I sort of understand a bit better. Still unsure why the one ton is so much different.
Couple pics, one ton axel is nice and clean, 3/4 ton is “weedy”

Re: Rear axle offset question
The HO52/72 from your 1 ton are off set like that. The dana 60 in your 3/4 ton is centered. Just a difference in axle designs. Also noteworthy here in my observation, most 3/4 ton Chevy’s got the Ho52, and GMC’s seem to have gotten more of the dana 60’s but this isn’t cut and dry.

Re: Rear axle offset question
Any idea on why it was designed with the offset?
I believe the 3/4 ton started life as a 72 Cheyenne Super that I sold the guy that owns it now. He parted it and this is all that’s left
