Left Hand Wheel Stud

[DollyDodge]

Does any one know where I can get a left hand rear wheel stud (and what the dimentions are? The left rear wheel on my truck has one right hand stud in it. I would like to replace it. The local auto parts only have right hand studs. I found a company on line that has them, but they have literally hundreds. They differ by length, diameter, thread, shoulder, and knurl.

I danged near bent my lug wrench on the one bolt before I figured out what was going on.

PS I got the fuel pump rebuilt and replaced and the truck runs well again.

If you haven't, try your local NAPA. They should be able to look up the number in the book. I replaced all the studs in my truck while it was apart a few years ago and the studs were on the shelf. Good Luck.

where are you, i have the old ones from my B4B sitting around, i dont need the fronts.

[DollyDodge]

I am in Bishop Califonia. I would gladly pay for the old ones you have plus shipping.

I did try Napa and they told me I needed to take the stud out of the wheel so they could measure it and order the correct one. Their books only go back to the 70s. I was next going to find someone with a press to punch on of the studs out.

[HanksB3B]

How could that happen?

[DollyDodge]

How could what happen? You mean having the one right handed stud on a left handed wheel? Someone must have broken on of the left handed studs off and replaced it with a right handed version. The right handed one is also a bit smaller and some knumbskull welded it to the wheel. I think I will attach some pictures because this is the second post I have done regarding this right hand lug living amongst the left hand world and I think folks don't believe me

wait, studs? i only have the bolts. sorry to falsely raise your hopes.

I was going to be helpful and look up the numbers in the book. But all I have is a Plymouth passenger car parts book and that shows wheel bolts. Looks like the left hand threads were introduced in 1940. Prior to that the part numbers for wheel hubs and lug bolts are the same for left and right.

Maybe the Dodge trucks when to studs before cars did. . .

Dodge 46-48 cars already had studs, it was plymouth that had bolts.

[48Dodger]

I don't believe 48-50 had studs. All mine have bolts. I'm sure its possible the the rear axle or front hubs could be replaced with later models that had studs. Of course I'm sharing from what I have and not what I've looked up. Any 48-50 I've come across that had lug nuts, I just figured the orignal axle/hub had been replaced.

Now I don't know what I have. The front and rear wheels both have studs in the wheel and have nuts that hold the rim on.

[DollyDodge]

I went to the old parts manual and it shows that B-2-B trucks had lug bolts and that B-2-C (my truck) had lug studs and nuts. The picture from the parts manual shows bolts, but the parts list shows studs for the C model. So I am back to where I started. Does anyone know what size the studs are and I would even be more grateful if somone had a spare or knew where I could get one:D

One more silly question, were you able to get the stud out without a press?

Did the parts book give a part number? Its amazing what you can find by typing that into the interchange lookup on NAPA Online.

The lug studs on my '92 had knurled edges and popped out with a press. I had started smackin'm with a 5# hammer, but after putting forth a great deal of effort to get that one out, I moved to the press. On the '92, the lug studs hold the brake rotor to the hub, so when I had to replace the rotors, and there was 16 lug studs to remove, switching to the press was a no-brainer.

But here's where things get a li'l fuzzy. My '49 1 ton has lug studs, and they did not have the knurled lug studs back then. I was told that they used a special tool to deform the head of the stud so that it wedges into the hub, something similar to a cold chisel. I reckon the 3/4 ton has similar style lug studs, albeit smaller ones. Popping those out would probably be best done with a press cuz they're probably froze up with rust. A big hammer should be able to knock one out, but take care with the neighboring studs.

Another suggestion, remove a lug from a different hub...that way you'll have at least four in each hub.

I have poped out studs by putting the nut on and giving it a wack with a hammer . I put the new stud in with a hammer wack too . Disclaimer ; I don't remember if these were mopars .

I just looked in a 1939 Dodge parts book.

in 1939 Dodge used both bolts and studs on the drums

Stud - right hand thread standard # 679118

Stud - left handed thread standard # 679119

stud - right handed thread oversier .025 # 687901

stud - left oversized .025 # 687902

Nut right #672969

Nut - left # 672970

Bolt 393984

Sorry but it does not state and sizes in the parts book on length, threads

There is a number in the parts list for the 50 lug stud. I will enter that in the Napa online site and see if anything pops up. I tried removing the studs with a hammer, starting with a small one and working up to a big one (brass). The studs didn't budge, I was afraid I might damage the wheel, or the stud threads. I am going to take a auto shop today and have them look at it.

[TodFitch]

Thanks for all this info. Unfortunately NAPA Online does not cross any of those numbers. I'm a little surprised about not finding 393984 as that lug bolt was used starting in 1933 on up through at least 1948. Seems like that would be enough years of production that Dorman or somebody would have a cross for it.

The numbers I got for the B-2-C lugs and nuts from the parts manual are

left stud 593979

Right stud 593978

left nut 580739

right nut 580738

Those numbers didn't cross on the NAPA online either

I nearly had a wreck at the mechanics. He tried to press the studs out and as I watched I saw all that was happening was the hub was being pushed down. He tried a couple of studs and not one would push out. Not sure what to do now. Maybe just live with a unique hub, 4 left hand nuts and one right hand. If I could get the dimentions of the stud I could get one, but with out the shoulder and knurl it is hard to know what to order. There are litterly hundreds available at Dorman.

[Dave72dt]

Your mechanic doesn't know how to usae a press to it's full advantage. A hollow spacer slighlty larger than the head of the stud on the inside of sufficient length to hold the hub clear of the press plate will concentrate the press directly on the stud instead of spreading it to the entire hub. It'll come out. It went in.

[DollyDodge]

Dave: What you said is very true (if it went in it will come out). I live in a small town and have limited mechanics and parts stores available. I might suggest to him that he try what you suggested. I still have the problem of finding a correct size replacement. I have looked at the list of Dorman left hands studs and none are very close in size to what is in the hub. I will keep working at it.
