M38CDN Front Axle Shafts

Post by L84dinner »

Disassembled my front axle and noted that I have mixed Bendix and Rzeppa shafts. The Rzeppa shaft (right side) has been modified to fit the Bendix flange. A new spline has been cut over the original.

Has anyone seen this before?

Any recommendations?

Hi John, I moved your post from our "Web Site Issues" Board here to the technical board where it belongs.

Not sure what issue you are having. The splines are the same dimension and count for the Bendix, Rzeppa and Spicer cardan joint axles shafts for the Dana/Spicer 25 and 44 axles used on the M38 and M38CDN. The early Bendix had a threaded end on the outboard splines for the front axle nut before the M38 came on line which was not used on later axles.

Can you post pictures of it?
I have extra front shaft if interested. I will have a look today and see what kind it is. I'm in Cambridge so not too far from you.

Here are a few photos of the modified shaft. Looks like they used an early Rzeppa withe the threaded. end.

Someone went to a lot of effort but I think the result is compromised. The spline looks weak.

I think I should replace with a Bendix shaft.

Hey John. My buddy has both front and rear end complete for a M38. I can check with him as to what he wants for them. They are up near Port Elgin.

John looks to me you have a pair of stock axles. One from a WWII jeep and one from a Post WWII jeep.

M38 Front Axle Shafts

Post by L84dinner »

Wes,

I am finally getting around to reassembling my front axle. You very kindly assisted me in identifying the axles shafts in my M38 last year and I wondered if there are any concerns with assembling mixed Rzeppa and Bendix axles shafts.

Assuming I set the turning stops to the lower of the two specifications do you see any concerns?

Many thanks,

John

No. The steering stops should go to the conservative setting as you posted is about it.
