2.5 ton Rockwell Third Member question
Question:
I have a Deuce with a bad front differential will the third member from a rear axle work in the front axle location? or is it reverse rotation like in a standard 4x4?
Searching for "third member" didn't work as did other combo's
Thanks,
Ed

The issue he is alluding to is that the orientation of the front axle is backwards compared to the rears, therefore, the rotation of the ring gear will be in reverse compared to the rears to make the front tires go forward. Ring gears are made to primarily turn one direction because of the cut of teeth.
If you simply swapped a rear diff in, the ring gear will have the backside of the teeth loaded instead of the front. I don't know what the Rockwells do for the front, but that is the concern.
Question: .....................will the third member from a rear axle work in the front axle location?
YES, they are all built exactly the same and perfectly interchangeable, as already stated. When pulling forward load is on the "correct"(convex) side of the ring gear tooth, in all 3 axles!

How is that achieved? Nevermind, there are two drive flanges....

Thanks G, after we looked at the gears we figured they would work but we had a heck of a time figuring how to support the truck, until we remembered our jig from our cam repair last year, it seems to be a universal jig/jack for everything!!!

Rockwells are really cool axles, the third members and hubs are the same front and rear. And when putting them in a custom truck they can't be put in wrong, they will always turn the same direction. You can even put a front axle (or a rear) in backwards with the pinion on the drivers side and the stearing in the front and it will still turn the same way!
