axle snaped

[tigger]

When i bought my m-35 the owner told me the left front tire would not pull. after getting it home i found the snapped off piece of the axle under the pass seat. 1953 Studebaker m-35 with timkin axles will a Rockwell axle shaft work or do i need to find a timkin shaft? Would like to replace the hole thing from punkin to hub, if it broke this I'm sure everything else it tweaked just a little. this is the piece that goes from the nuckle to the outer hub.

you will need a axle with the same type of joint,,, U joint or CV, If it is U joint they will be interchangeable but if it is a CV shaft you should get the whole axle. Just installing one new tulip you might have issues, premature ware and failure.

The old Timken marked axles are the same as the newer marked Rockewells.

Which front axle joint does it have? Bendix or Spicer? You do not have to match sides but do need to be sure that the steering angles are acceptable to the most restrictive joint installed.

I haven't tore it down yet to see. that is going to wait till old man winter leaves!

If you upgrade from the old ball style to the newer u-joint style it will NOT just slide in as a replacement. The seal retainer that presses into the end of the axle tube is different. If you try to put a u-joint shaft in where an old ball style was it will not go in far enough, you have to replace the retainer with the seal.

I plan on replacing everything with new when i tear it down, but thanks for that info. it will set a few weeks tore down while i wait on parts after i see what i need. I hate to do thinks over, would rather do it right the first time!

Just curious witch joints are stronger? I would have thought the joint would have let go before the shaft.

Wow that is a loaded question.
Depends on who you want to believe, the materials guys, the "off road" guys that run the big axles, the test and evaluation technicians that push the parts, or the engineers that design the parts.
I personally like the materials guys, the test technicians, and the design engineers that all seem to agree that the Bendix joint is the superior joint except in cost.
We have failed many Spicier joints but have yet to fail a Bendix joint, we have failed shafts attached to the Bendix joints.

The u-joint style are better all around, better material and stronger joints.

Do believe if it says timkin it has cv.

I will definitely take the advise of a man who gets paid to break thinks!

Tie6044, any thoughts on why the Spicer joint does not meet the military requirement for front axle joints? (Based on the statements from the U.S. Army Ordinance Center Sub course OD1006 for Wheeled Vehicle Drive Lines.)
"The front axle shafts must be able to pivot in the steering knuckle, and there must be a
universal joint to transmit power at an angle. A single, conventional universal joint (the
type used in the propeller shaft) does not meet military requirements for use on the front
axle assembly."
