Re: IML: Changing the Left to Right

[Brad Hogg <luxoliner@xxxxxxx>]

The 60's rims and studs are the same as the 70's rims and studs and I've 
never seen left side wheels flying off a 70's Mopar so I'd say the LH thread 
idea was a pipe dream that has been proven neglegable if not false.  Change 
those studs over is my advice.

Hi Nigel:

Disagreeing is fine.

I know why Chrysler used left hand threads on the driver's side. I was
not aware of other makes that did, but most of my knowledge is 60's and
70's American vehicles. I grew up in England in the 60's but do not know
much about the cars.

I just think that history has shown that it was not necessary to use left
handed thread lug nuts. I would guess that the left hand threads have
caused more problems than they "might" have solved.

 If I was an automotive engineer in the position of choosing whether to
use left hand threaded lug nuts you would have to really prove to me that
the right handed ones did not work. I lived in St Louis for ten years in
the "Show Me State" and you would have to show me.   :)

Thanks.

I hate to disagree but many many different marques have left hand and
right hand threads for the wheel attachments, particularly if the car has
knock on spinners for wire wheels. In this case I am generally talking
about pre war european sporting and luxury cars, having little knowledge
of american cars other than Chrysler and Hudson (whose chassis formed the
basis of the Railton and the Brough Superior in the UK. The reason that
wheels have left and right hand threads is very simple, the rotation of
the wheel creates a centrifugal force on the wheel attachment and by
having the different threads both have a tightening effect, have the same
thread on all wheels and there is a potential to loose a wheel, much less
likely with bolt on wheels, but I have seen a race where one car had its
half shafts and therefore hubs reversed and as a result lost both rear
wheels... they were KO wire wheels where as I said before it is more
critical. So Chrysler did it not for the sake of being different but
because it was the correct thing to do from an enginering point of view.
