built in Canada.

Because of sitting over the past couple of years, the brakes needed
repair, so I started on the project around 9 this morning.

I would just like to point out to my Canadian friends, that it's
leftie loosey, righty tighty.

Not leftie tighty, righty loosie.

If you are speaking of the lug nuts, one side is left hand threaded to
prevent the lugs from loosening. There are a lot of applications like
that that make left hand threads essential.

Knock off hubs yes, lawn mower blade nut yes, but lug nuts....someone wasn't
thinking.

That's just silly.... unless we are talking knockoffs. There is
nothing intrinsically thread locking about left hand threads, unless
they are coincident with the axis of rotation.... and lug nutS aren't.

If the only forces to worry about were axial, then theoretically, lugs
would only need to be tight enough to hold the wheel to the hub, like
finger tight.

My 1965 Barracuda was the same, but that is probably a hold-over from
the horse and buggy days where you *had* to have left hand threads on
the left hand side of the axle.

Wow, small world.....I had two Barracuda vehicles. 1964 Formula S with Hi
Performance 273 engine and 1968 Formula S. with the 340 engine. I loved
those cars! Wished I had either one today.......

Too keep the sloppy wheel from unscrewing the nut as the car moved
forward.

So, I should have been expecting a wheel to fall off since my 1972 4WD
GMC 2500? After 33+ years (30K per year) of GM products I should
expect a wheel to fall off on the left side?

Still waiting.....

Actualy it comes from way back in the wagon days. The wheel nuts
didn't have a fixed (non-turning) washer between the wheel and the nut
to keep the turning wheel from unscrewing the nut.
Therefore...left-hand wheel nuts on the left side.
I'm don't think horse/wagon rigs had to worry about backing up. :o)

They backup all the time. Watch the Budweiser horse team put on the show
sometime.
