Sounds like the keyway might be the culprit.


Shaft should be 1.372 +/ 0.001 as it leaves the bearing, and taper to 1.122 at the outer end (1.00 inch taper per foot.) But that's just one old mans opinion.



The Specs were on the other page.

Just to put some semblance of closure on this thread, I thought I'd let everyone who suffered through this with me know that the axle from my '48 parts jeep fit my drum like a glove.  Had to reshim a little, drove in the key, added the castle nut, cotter pin, wheel and off for a frigid ride around the block.  Got both axles boxed up and ready to head back to KW....just not going to be able to make them work without throwing more money at them.  Thanks to all for the help in sorting this out!

I hope it works but your comment about driving in the key makes me wonder. If you do it correctly the key will slide in using your fingers. If you had to drive it in, it was probably upside down.

And if it was upside down, you just cracked your hub... Ouch

I've played that game before. I screwed up once. I was wondering about a leak on my Commando axle. Yep, a PO did it wrong so I went out for used parts. I got a good used hub and the counter person started piling bad hubs in a box for me to take away. I suppose that is how they get rid of the junk.

I have no idea.  The Omix and the NOS were identical in almost every respect.  KW's website says, "These are NOS original military surplus from Europe.  Limited quantities are available."  I have nothing to compare to except the new OMIX ADA which it looked just like (except it had kind of a sand cast look to it in its unmachined areas) and two axles which were probably original out of a '47 & '48.  It looked nothing like them.  I have not looked specifically at M38s or M38A1 axles to see if the design/machining specs may have changed.

Oh, ye of little faith! Big smile  It was not put in upside down.  The key and keyway on that parts jeep axle was far from finger install-worthy.  "Drive" may not have been the most accurate word to use.  I "helped it along" with a small hammer and a length of brass rod.
