i remember an old jeep and maybe a old ford dump truck having reverse threads on the left rear wheel.? Was the model A desigend before that was thought to be a good idea. Or has my car had its studs changed?

I know Chrysler did that left hand thread thing in the 60's for some reason. But sounds like your car had it studs changed for some reason.

The lug studs on a Model A are right thread.

Many vehicles [ not just Chrysler products] at one time had left side studs/bolts as left thread. Right side studs/bolts were right thread. Apparently it was felt they would tighten rather than loosen.

The Model T's right front spindle was left-threaded so that the wheel wouldn't work itself loose as it rotated forward. Both the outer bearing and retaining nut were threaded to match. A real P.I.T.A. these days when going through a box of parts, looking for the correct threaded bearing and nut! Ford got it right in 1928 by eliminating this unnecessary design.

Dodge trucks in the 40ts had left hand threads on the right hand side wheels. It makes no sense to me. The spindle bearings I see how that could help on the driver side. But would be very confusing to those who did not know.

When I was a 12 year old boy I remember my Uncle trying to get the front wheel of his Dodge 1949 2 1/2 ton dump truck. I said to my Uncle what does that L mean on the end of the stud. He never forgot that.

I can remember running across a car, Desoto maybe, that had RH and LH studs and nuts on one end, and RH and LH lug bolts on the other end. Eight different part numbers to hold the rims on. Wow, seemed weird even then.

And now someone will tell me I got the parts count wrong :-)

I think my AA has the reversed threads on the left side.

Mitch//pa · 12-26-2015, 02:03 PM

Usually the L/handed studs had an L stamped on the end so one would know which way to turn the nut. Many times a stud was snapped off due to trying to break them loose in the wrong direction... I remember them on the 70's Chrysler products...

Henry's Lady's Man · 12-26-2015, 02:26 PM

FWIW, my very first car, my dad's 1960 Pontiac Catalina, had left hand threads on one side (can't be sure of which side).

Tom Wesenberg · 12-26-2015, 02:41 PM

Studebaker also has some left hand threads on wheel studs. I think they stopped after the 1950 Models, when the Champions went from 4 studs to 5 studs.

I think I also recall the 1930 AA I worked on had left hand threads on the left side.

This was a puzzle on "Click and Clack" years ago. A guy had a flat tire and couldn't get the wheel off, then called a wrecker service, and they broke a stud and quit. Another guy came along and easily removed the wheel. Why was he able to do what the others couldn't? Of course the answer was he was driving an older MoPar and had the flat on the left side.

My first vehicle, an AA, had left hand threads on the left side.

SeaSlugs · 12-26-2015, 11:54 PM

yup aa's had left Jan threaads on the drivers side. Granted someone's not put right hand hubs on left side and vice versa

Drive Shaft Dave · 12-27-2015, 12:16 AM

Years ago I used to have a 1 and a half ton1928 . The left side had left hand lug nut to tighten. also 1968 Dodge dart with the same.

RichPA · 12-27-2015, 10:11 AM

A few years ago I was given an old Willys pick up that sat for about 40 years. The gentleman said there were some extras for it in the shed. Recently the shed was cleaned out and among what was found was a pair of dual rear wheel adapters which included the left hand threaded studs to mount them on the left side. Rare find, I think. BTW, I was able to free up the "Super Hurricane" flat 6 and it runs fine.

30aadoodlebug · 12-27-2015, 10:38 AM

My 30 AA has LH threads on both the rear wheels.

Farrell In Vancouver · 12-27-2015, 10:57 AM

30AAdoodlebug has two left hand side drums. All AAs had left hand threads on the drivers side wheels.

rocket1 · 12-27-2015, 02:58 PM

I put the impact on the wheel stud nut,on my 50 olds,sheared it right off.I didn't have my glasses on couldn't see that little "L"

My1930ModelA · 12-27-2015, 05:48 PM

I twisted one off too on my '58 Dodge Coronet in 1975, and just replaced it a few years ago!

Patrick L. · 12-27-2015, 05:59 PM

Not to worry, we replaced a lot of twisted off studs back then. It happened fairly often.

Every now and again we would find where someone had left thread studs on the right side and fixed them too.
