I'm sure John will chip in, but I hope you've managed to get a new tapered/split washer that goes behind the nut. When I first bought my Maxi (in 1976), the hub nut was "loose". After tightening it several times, I still had problems. I went to my (late) tame BL mechanic and got a lecture about replacing the cone washer (I can't remember the technical term). Once I put a new washer in, the noise stopped - apparently it was a use-once item (I had several old ones floating around - and I think I still have a couple).
I don't think I ever used a torque wrench - the tame mechanic never used one, preferring the "dog tight" method that he taught me! I think that was when I bent the tee-bar too!

No! Maxis have castellated nuts and use split pins, Loctite - where its use is appropriate - is applied as a liquid which reduces the reading for a given input before it's dry, by which time it's too late. hub nut tightening torque on cars such as ADO71s, which should use Loctite, takes this into account.

I regularly use nuts that require 1500 lbft of torque, and also use stretch bolts with about 20,000psi for the big stuff but thats another story.
If you use an extention of no more than 3 feet and pull it tight that should do the trick.

This is the nut.
Here you see 6 interconnected stud jacks connected to one pump, each jack is pumped to 20,000psi and streches the stud by about 3mm you then simply spin the nut back.

Does that mean you do 3/4 of the job, 50% as well as it could be done for 10x the price?
more seriously, I am jealous of the big toys you get to play with every day. The biggest bit of equipment in the factory at my place of employment is a 50 ton press.
