How to secure a drive shaft nut?

[misterg]

Doesn't help at all. You're a killjoy. You've spoilt what was turning into a very satisfactory row!

Now we'll have to think of something else to insult each other about.

My humblest apologies! - Please carry on without me

Thanks Andy. Definitive as you say. I'll torque it up correctly and keep a close eye on it, with some loctite in reserve I think.

I'd use Loctite anyway...

Anuvver Enjinier ere, an a mareen wonn at vat.

If you use Loctite and torque to the correct setting it should be ok. I've always been told that Loctite prevents the start of inadvertent loosening. You should easily be able to break the loctite bond when/if you ever need to disassemble it, and as other forumites have said there are grades which are designed to soften at relatively low temperatures to facilitate disassembly.

Good luck!

Interesting how Wikipedia encyclopedia describes Loctite.

Well aware of the unhappy practice of staking car drive shaft hub nuts - and arent they a pig to do after an overenthusiastic garage hand has done them!

Why "unhappy"? it seems to work fine. I can't say I've ever had a problem undoing a hub nut, as long as I remember to crack it off before I jack the car up!

It's almost impossible for a garage to get "over"-enthusiastic as they tend to be torqued to an enormous torque anyway to preload the wheelbearings. Another great feature of this kind of locking technique (compared to other types of self-locking nut, thread locking compounds, or simple tightening to a specified torque), is that one can tell at a glance whether the operation has been correctly carried out - something in doubt in the OPs's situation. Similarly subsequent inspections to see if anything has moved are also very simple.

i think it has a lot going for it! (though in the OP's case, there's not really enough spare thread, so I appreciate this is "academic" anyway!

Unhappy - 1. knocking a precision component about. 2. A Birmingham screwdriver in inexperienced hands can do a whole lot more harm than good. " If you cant fix it, get a..."etc

Not sure where this "knocking a precision component about" concept comes from - they're made like that, it's not something the garages "do" to the driveshaft after it's been manufactured!
