Otahuhu Posted December 16, 2012 Share Posted December 16, 2012 What side of vehicle has the left hand threaded nut?If the left hand nut is on the right side of car wouldn't the wheel rotation lossen it?Is there a technical reason as to what side of vehicle a right or left hand central lock nut fits?

I made the mistake of putting a left handed hub on my MGA right side once. The knockoff unscrewed itself and my wire wheel went out the back of my front fender, rolled across the intersection and ended up on someone's front porch.

Otahuhu Posted December 17, 2012 Author Share Posted December 17, 2012 Layden The questions raised relates to a mechanical /technical matter, not to equinoxes that occur in each sucessive sidereal year Appreciate if someone could answer my queries as it relates to the vehicle in question Thanks Link to comment Share on other sites More sharing options...
keiser31 Posted December 17, 2012 Share Posted December 17, 2012 I am pretty certain that if my MGA wheel knockoff unscrewed itself, yours will, too. I doubt that there is someone on the forum that has had that happen to their Stutz. And yes....usually the left handed studs, nuts or caps go on the left side of the car.

Layden B Posted December 17, 2012 Share Posted December 17, 2012 (edited) Am sorry you misinterpreted the words. I suggest you go to Wikipedia and search for mechanical precession and you will find how the hubcap can unscrew or self tighten.Here is a link (I hope!) http://wikipedia.org/wiki/Precession_(mechanical) Edited December 19, 2012 by Layden B (see edit history) Link to comment Share on other sites More sharing options...
Restorer32 Posted December 17, 2012 Share Posted December 17, 2012 Think about it like a ratchet wrench. Any back and forth movement of the wheel on the splines causes the cap to be loosened in tiny increments until it comes off. Link to comment Share on other sites More sharing options...

keiser31 Posted December 18, 2012 Share Posted December 18, 2012 Left hand threads on the left side, right hand threads on the left.OOOPS! Link to comment Share on other sites More sharing options...
sambarn Posted December 18, 2012 Share Posted December 18, 2012 The Buffalo hubs are labeled Left side and Right side with directional arrows. The threads are quite deep and will not go on the wrong side. There is a bit of an art involved in getting them on and off but not hard to do. You don't by chance have a spare left side on do you? I need one for the Marmon in my avatar.-Sam Link to comment Share on other sites More sharing options...

Marty Roth Posted December 23, 2012 Share Posted December 23, 2012 Simple Answer ---It has to do with centrifugal motion:as the wheel turns in a forward motion, if a "left wheel" with a conventional; right-hand thred were not properly tightened, the spinning (centrifugal) motion could cause the nut(s) to loosen even more, causing the wheel to come off of the car. This happened to me late one night on the NY-17 Quickway. A "mechanic" did not tighten the lugnuts on the left front wheel of my '58 Impala convertible. I lost a wheel at 60 mph -- not a fun experience !My '66 Dart GT convertible and my daughter's '66 Baracuda, as well as Dad's '57 and '56 Plymouths all had left-hand lugs on the left (driver's) side.

JV Puleo Posted December 24, 2012 Share Posted December 24, 2012 Interesting... the rear axle of my 1910 Mitchell is full floating (the wheel is mounted on the axle tube and not directly attached to the axle). The ends of the axle tubes have a LH thread on the right side and a RH thread on the left side on the threaded collars that retain the wheel bearings. Its always been like this as there is no way to change it. Link to comment Share on other sites More sharing options...

Maybe something from the instruction book for the car? Link to comment Share on other sites More sharing options...
Guest brorag Posted December 25, 2012 Share Posted December 25, 2012 as opposed to gyroscopic precession? Link to comment Share on other sites More sharing options...
