Front Axle Studs on W350

[RSchwarzli]

Question for you.

Due to the 19.5" aluminum wheels I am putting on the crew cab, I need longer studs. Anyone know what the spec is for our studs? What size the hole is for the stud to press into, knurl info, etc? This truck does have the 5/8"x18 studs. I just don't know the rest of it as I have not yet pressed one out.

Thanks!

Robert

I'm not sure one knurl size, but I was thinking the thread would be 9/16-18.

You are better off taking one out and checking, its my understanding that there are 2 different knurl sizes for the 5/8-18 wheel stud.

On the duallies they are 5/8.

Gotcha. I will hold off ordering till I get one out then. Thanks!

What make of rims??

If those rims are like American Racing/ American Eagle they will use a extended shank lug nut. The lug nut centers the rim.

Here is a link that shows them.

That's why your current studs are not long enough. BTW I don't think you can get longer studs eather.

American Force.


Oooooh yes. THAT kind of nut.


Hmmmm. I hope I am lucky then and can find something. Would be surprised if not available.

 

[RWherley]

Back when I was looking at wheels before I got mine I seem to remember that American force made wheels specifically for the first gens with the 5/8 stud pilot hubs. So they should have the nuts you need

 

[RSchwarzli]

Actually, AF sent me metric nuts. LOL The issue I have is length once I get the custom trim rings on.

Duallys were available with 9/16ths and 5/8ths. The 3500 pound axle had the smaller studs. NAPA was able to tell me the correct drill size for the studs, however, the 5/8ths studs also have a counter-sunk hole, sort of, that is for the budd flanges on the wheels, the lighter wheels weren't budd.

Sorry... gotta call bs...1stgen dually have always had 5/8 studs. And the wheels were not budd but coined. And all dually wheels were coined until 2ndgen.

A 3500 lb axle is a dana 44. It was never used by the factory in a diesel truck. It could barely hold up with a small block on top of it. A BB could eat them pretty easy. A 5.9 would most likely bend it.

The biggest studs I have seen in a 44 are 1/2" by any of the three OEM users.

 

[RSchwarzli]

So, the stud is 5/8-18 with a .715 knurl. Length is 2-7/32. Shoulder is 19/32".

This was used on Chevy and Dodge applications only and from what I see, it is not available any longer than that length. Replacements of the stuck unit if needed are available from Doorman part 610-281.

Anyone by chance know of a place that has longer bolts of this spec?

I had 1980 Rams with the 5/8" studs. With single Budd wheels and coned lug nuts, torque spec was 225 ft lb. On a dually with flanged nuts, not coned into the wheels, torque was 325 ft-lb.

Good lord!

 

[Joseph Donnelly]

Not sure about 225, it might have been "only" 200. Long breaker bar, cheater pipe, etc. lol.

Look at the Dorman 610-049.... 3" long, but the knurl is a bit smaller.... might work if your hubs aren't too loose.... They were for the Chevy's that had the outer steel ring on them and the 1 1/16" lugnut.... And if you are trying to find a Dodge front dually hub, the Chevy's will work, but you gotta change your calipers, too...... Just FYI....

Only other option after that is Strange Engineering or maybe Moroso Racing.... I know Strange made some 3.5" long screw in studs I used in a 9" Ford axle years ago....

Eagle Alloy makes the 5/8" shank lugnut with washer.. part number ACL8890.... Summit carries them, and I know a guy I can call if you like. They've been hard to find in quantity for some time.....

JOE!! I remember those days.... traveling with my mother, I had to change the tires.. :{ Dad kept two acorn style lugnuts in the toolbox to center the wheels before tightening the crud out of the cone nuts.... I had a piece of 1" chromolly pipe leftover from a chassis build, and it made a great cheater pipe to slip over the break over, with a piece of wood under the extension to keep it straight..... I can't say I miss it. I've got an air compressor and impact wrench, now!!!

Go look at Ford Motor home chassis especially class A motor homes ive sen them running Aluminum wheels and i know the lugs are Dodge size as a freing scraped out the truck and he gave me the bucket of lugs i pulled off also super duties come oem with 6 aluminum wheels

I can Make any stud you want in any size you want. It will not be cheap. But I can solve the problem instantly. Pm me if interested. The best idea would be to put the stock wheels and tires back on the truck !
Tall and wide tires like to break the steering gear out of the frame....19.5 tires have lower side walls and ride rougher than the 16's . Road shock also cracks up the body !
