Hey now, don't knock that axle too much.
Its pretty much the same axle on my old Jeep. I put over 200K on it, and built roads through swamps with it.
Mostly by backing off and ramming trees until I either drove over them, or hooked up my winch and dragged my Jeep over them.
In all that time, the only repair I had to do, other than brakes and some hub work, was replace the top weird looking Timken bearing.
Once I figured out why it went bad, I never had to do it again.
That axle was designed in WWII, and had no disconnects, since you did not want to get out and lock hubs with people shooting at you.
As a result, the top bearing was splash lubed by the Rzeppa joint running in 90 weight inside the knuckle..
After Warn invented the locking hub, the axle did not turn as often, and the top bearing did not get lubed.
So, when I realized that, I made a point of dropping it into 4wd with the hubs unlocked a few times a week at red lights.
Drive about a block, and kick it back out.
The first and only time I ever wrote to a national magazine was because of that knuckle.
I always kept the rubber and felt seals in good shape on mine, and it never leaked. I changed the oil after every hunting season to get the water out, and it was always full of oil.
Somebody wrote in to one of the big magazines, OffRoad, 4wd, one of those, asking how to stop the 90W from leaking out of his front knuckles.
Their so-called expert assured them that every Jeep manual since 1944 was wrong. That you were supposed to run heavy axle grease in those knuckles instead of oil. That there was no way oil could stay in there.
I wrote him a scathing letter, assuring him that my knuckles were full of oil, had been for the past 15 years, and did not leak.
Not only that, but I could point to dozens of Jeeps and trucks around town that had oil in their knuckles with not problems.
Plus, of course, with grease, you would not get any oiling of the top bearing.
Never heard back from them, of course.......
So, have a little respect for that old design. It may seem outdated and weak these days, but thousands of GIs owe their lives to it.
