 Wellsmile

It was found very early in automotive history that left hand threads on the left hand side and right hand threads on the right hand side resulted in more secure wheel nuts and axle nuts etc. This is because the tendency to undo is countered by the relative rotation. That is a well known fact and most heavy vehicles use that system. It was not imposed by a rogue engineer on the drawing board. hmm

As for the machine with every second gear being reversed. I have had to repair a high force testing machine 100T that was equipped with one of those bl**dy gearboxes. After the second disaster when an operator got it wrong and destroyed something by switching the motor the wrong direction, I made a mechanical lockout plate so the correct motor rotation could only be selected if in the right gear. How stupid was that design !furious

 I have a 1967 Prince Skyline GTB  (mid '60's Japanese car ) with LH wheel stud threads on LH side - maybe one of the last cars produced like this...who knows....the idea confuses alot of younger people if they have never seen/used a LH thread before. As you said -Still common on some trucks though....

Getting back to the original posters question, should we lubricate wheel nuts

I have torqued a few wheel (and other type of) nuts, and mainly found, that if the manufacturer wanted the threads lubricated, they would say so

I have personally never used lubricant, on a normal vehicle wheel nut/bolt

I also doubt if a normal traveler, would carry lubricant with them

As an ex mechanic, we never had a problem with a bit of lube on nuts if needed, but only if needed.
Never had any wheels fall off in 30yrs

Reading up on the subject on the net, I learn't quite a bit. Apparently its not just the lube, but the type of lube. To use or not to use will be the never ending question.
