LH Thread/ RH Thread? GEEZ!

by **cv70chall** » 19 Jul 2008 16:58

I never knew of Mopar (At least not with my 74 Charger) having LH threads.
I'm getting ready to order a new set of chrome lugs- and as with everything else- want to be SURE that I get the right ones for my 70 Challenger.
I'm going to go with RH threads.

..I think..

Yep. Drivers side only. Most 1960s and early 70s Mopars had them. Apparently they were less likely to come off that way around on that side of the car.

Trouble was that most of the apes in tyre outlets didn't know this when they put the impact wrench on there so most have had the studs sheared off at one time or another.

A couple of mine were gone when I bought her so I replaced all of them with RHT studs.

Most 1960s and early 70swhat kind of drugs were they on , i heard that the rotating direction was the culprit,man its kinda silly if you think about it,it makes no sense to me but im not an engineer from the 60,s :s024:

and yes i changed every mopar ive owned,some shops ask if its still stock, i repeat some shops :disbelief:

yes the original studs on the left side of the car were lh thread it seems weird & i often wondered why but at work we have mitsi trucks & if you dont check the left side wheel nuts regularly they do come undone & you lose a wheel i guess they were trying to avoid this problem

The left hand thread design must work, mine have never come loose. :lol:

Mine is never on the road long enough to come loose. :roll:

Best place to get my hands on a complete set of these? I want to replace them all.

The left hand thread design must work, mine have never come loose.not to talk smack ,but to me there are millions upon millions of cars on the road that have right hand threads on all 4 wheels and they too have never come loose,so go figure, after all i dont know when they switched, but they did for some reason or another,maybe cost? :frown:

like i said not trying to start anything i just feel that it is amazing they did that while all other car makers were using right hand threads,and like dave said young pups seem to just go and shear the stud right off, and in some cases they dont have a replacement, so you have to go with out and order a new , i feel that they should be taken out any way because they are 35 plus years how many cycles has the metal gone through? alot,they will break not if but when, i would change those things out asap! sorry for the ramble i have had some night mares with shops with those pieces of crap! :rage:

hate em!

I know Drew, I don't let kids at tire shops work on my car anymore. They have stripped out the center cap bolts, chingered up the finish, and over torqued the lugs. I only take in bare rims to be fitted and balenced.

The left hand thread on the driver side is what came with my car. I try to stay original as much as possible. I think even in my old age I can remember how to remove them wheels right though. :roll:

Or was that left. :lol:

The idea behind the threads was that if they ever came loose, the direction of rotation would keep them from backing off any more. Following that theory, I wonder why they didnt have one of the steering wheel nuts set up the same way. :hmmm:

And I've nearly killed myself a couple times trying to "loosen" left-hand threads with a tire iron. I keep thinking they're just REALLY stuck. :s001:
