mystery axles

[Corey Myronuk]

Hi. I've recently come into a pair of GM axles and im a little stumped trying to figure out what they came from. They have a nice set of 20" combat wheels,big 60ct brakes but the rear diff is offset to the side (right)and the steering is on the left.
I was thinking they may have come out of an otter but the pics have the operator on the right..
What do you experts say? Im out of theories..

Thanks

Does it look like the steering arm and bearing caps might have been switched side to side, moving right to left, to throw off identification? I've seen cases where people did that as part of a plan to create a LHD C15A.

Corey,

I just had a look through CMA-01 Chevrolet and GM Illustrated Catalogue of Major Assemblies dated August 1944 and I cannot find a match for the front axle. None of the axles have a steering dampener setup like yours and none of them have steering on the left. I will echo Grant's thoughts that potentially someone modified the axle to suit their application.

The rear axle appears to be a 1799433 with applications listed as C30, C60S, C60L and CGT. (It is the only rear axle with that style of cast differential housing).

From the freshly disturbed rust on the spring mounts it looks like they were recently removed from a vehicle. Do you know what they came off of and could this explain the front axle's steering setup being modified?

Hi All

I noticed steering damper as well, two of my CMPs have these, both after market, both installed by me, so suspect they are a later addition.

As to moving the steering knuckle from one side to the other, that is a really interesting idea, wonder if the bolt holes line up.

Cheers Phil

Not having any materials to back up my suggestion, but maybe off a postwar GMC 2 1/2 ton M211?

One of the examples of steering arm being switched side-to-side I referred to is my C15A. The steering arm was mounted to the left knuckle (fit fine there) as part of a conversion to LHD planned, started but not completed by the previous owner and fit properly when I switched it back to the right side.
The axle is not likely M135/M211, it has little resemblance to the axles that were on the M135 I used to own (or the images in the manuals).
