Anyone seen this before defender steering box shaft sheared

Now that's a first for me too......

I am a Design Engineer, and modes of material failure are important to me in my design work (knowing how materials behave is quite fascinating to me) and I have to say, such a clean break is quite a phenomenon and impressive to see on such a large diameter rod without signs of elongation and necking...I know it is hardened but for a clean snap like that is unusual. I would be very keen to know 'how' that failed!

I can see what but what did he do to it?

Is it a NEW Anti theft device that owners of Defenders don't now they have fitted ? Until it thinks it's being nicked

They're not really supposed to do that are they??

Combination of heat treating and the machining process.

Gatso, could you please post a well focused big closeup of 1. the broken end and 2. what it broke away from, I know this will be up in the PAS box but if you could get a shot in there it would be quite helpful in trying to ascertain the mode of failure.

I dont see the problem unusually the tab washer is still good

I'm no expert but could that be a casting fault?

Oops, i bet that raised the old blood pressure when that went.

Thanks, it is now with my people - they will be able to have a good stab at the mode of failure.

Please don't ask to borrow mine any time soon.

Material failure due to manufacturing fault. Or. the steel was knacked before the part was made. Same difference, you still walk home.

All without the aid of a made up degree,,,,,,,,,,,,,,,,,,,,
