Left hand thread lugs??
Well, I thought I would share my experience with my 84 F250. I must have spent two hours trying to remove the drivers side rear wheel only to realize after taking it to a tire shop that its left hand threaded. All the other wheels on the truck are regular thread, and that one wheel has its own set of lugs. I dont see the practicality of this system, and if anyone was thinking of removing the rear wheels to be aware of this.

someone has changed your studs out for ones for a dodge. I am not aware of ever finding reverse lug nuts on a ford. if it dosn't bother you that way, leave it, if it does, pop them out, and put in the proper ones for a ford

They did put lefties on some, my dad's 84 has them on both front and rear wheels on the passenger side. The thinking was to keep the lugs from working loose... my 86 does not have them, so they didn't run with it very long.

All of his pass side lugs have the L on them, and the rears are factory, as we have had it since it was new. The rotors have been changed though, but it retains the lefties. It also has the D50 up front. and a Dana in the rear.

I remember the first old Dodge I encountered that was like this, lol. Why the hell did they do that? The passenger side was normal, and the driver's side was 'backwards'.

Ford began doing this on trucks in 1932. These specific studs have been used since 1970.

My 83' F240 4X4 has a semi-float dana 60 in the rear end and the drivers side is left hand threads. I found out the hard way also, after a 4ft breaker bar which I stood on, it got so tight that the lug went through the steel wheel.
I am taking that whole crappy axle out and putting in a D70 with normal threads.

The Dana rear axle I got off of a 1984 F250 HD also had left hand threads on the driver's side. Makes for real fun when you get new tires and forget to tell the shop about the LH threads. Your first clue is when you hear the noise of an air impact wrench trying in vain to get the driver's side rear wheel off.

Don't change them to right hand threads, if they are left handed.
They are that way for a reason.
It's all to do with Centrifical Force and the GVWR of the vehicle.
The idea is the centrifical force of the trucks wheel going down the road forward will tighten up the lugs, or keep them tight with left handed on the left, and right handed on the right. If you change them to right handed on the left, it could loosen up and the wheel can fall off.
All large trucks have left handed lugs on the left for this reason as well.
The more weight the truck can hall, the more prevelent the reason becomes.
