Stub Axle Thread Stripped?

[Robsey]

Hi All,

I am still plodding at a snails pace with refurbing the old boogie-bus.

Anyway the general gist is that I have just replaced all the brakes on the rear left hub.
Thinking that I had 'boxed off' that wheel, I thought throw it all back together.
Throw the hub nut back on, tighten is with a 3ft bar, but no real effort, so not a huge amount of torque.
The nut spins on so far, and then it suddenly realeses.





This seems like a stripped thread on the stub-axle itself.
I thought that these were meant to be subject to a huge torque when setting up.
So my question is...
Should the thread strip that easily?

I am sure the hub nut had never been off betwern 1983 and 2019.
The nut was only removed in 2019 to allow me to remove the brake drum and back plate.
The back plate was toast.



I have not torqued up the nut since?

So chuff knows how the thread has stripped.

Threads can strip just by undoing the nut , is the axle damaged or the nut or both?

[Robsey]

I think it is the shaft that has partially stripped.
There were fine strands of steel within the threads of the shaft.
And as daft as it sounds, I thought that I felt a perceptively minimal reduction in diameter for the 1/2" or so of thread adjacent to the hub face.

It just baffles me the poundage of torque recommended if a thread can strip so easily.

I have a good axle and nut

Hi Davidoft1,

pm sent.

Best wishes,

I had best order a bearing kit and split pin from BW next week.
