LH and RH Thread Lug Nuts

[Bob Jordan]

SORRY to ask but I am finding conflicting info everywhere. Our 64 Sport Fury has RH threaded lugs on the right (passenger side) but the owners manual makes it sound like the RH threads should be on the driver side. Most internet "experts" say the LH threads on left and RH threads on right. I don't need an explanation why - we just want to know what the car would have had when delivered new. Thanks!!!

Lefties on the left (Drivers side).. righties on the right..

That seems to be the consensus. The original owners manual says to turn the lugnuts on the passenger side CLOCKWISE to loosen.

Left hand is always on the left side.

Thats either a misprint, or simply wrong. Left hand threads on the drivers side (assuming you are NOT in australia), right hand threads on the right.
There was an engineering reason, to keep the left side lugs from loosening. Chrysler did that from at least pre-33, till somewhere in the mid seventies.
Lots of cars have been changed, however, because lots of tire jockeys dont know any better, and bust the left side studs with their air guns.

Sound like a bad thing.

So true.

Every older Mopar I've had.....left on the left. Wouldn't make sense to have them on the right.

Very true the lefties were for a reason.

Thanks everyone. Usually when I ask a question like this I get advice to "GO READ THE OWNERS MANUAL!"

Did some quick research. Besides mopar, some ford trucks, some pontiacs, international pickups, studebakers for decades, and i think some others, not to mention every british sportscar with knockoff wire wheels. All used left hand threads on the left side of the car. (Do NOT refer to drivers side with british sports cars!)
Oh, Rolls and Bentley used left hand threads too.

Not that way here.

I've seen it before. Doesn't happen very often thank goodness.

Studs and/or nuts on the left were also color coded copper for quick reference, and the stud either on the stud side or head side (can't remember, and not at home to check some old studs) had a L or R in them.

Interesting typo/mis-information.

Stud side.....but sometimes hard to see it.

Easy to just put a wrench on and go with feel.

Is that a period original, or a reproduction?

Some of those books have been reprinted in China, and I have seen some horrible copies with mistakes in them.

Reminds me of a guy at work....a machinist no less that needed too remove a wheel from an older Dodge chassis motor home and broke off 4 studs before taking a look at them to see what was up LOL
