After-market wheel studs

[Guest]

Working on the '58 Scotsman and hoped to convert my left threaded driver side hub and drums to right threaded wheel studs. As a p/t parts driver for our local Autozone, I searched for the studs using year, make & model. Our computer gave me a Dorman number for a box of 10 for my car. Great! Took both the drums and new studs to my machine shop only to get a call a day or two later saying the new ones are slightly larger and won't work. The owner of the shop said this has become a common occurrence lately with after-market studs.
He suggested I contact a Stude vendor for NOS right threaded ones, which I have. Wondering if anyone else has had a similar situation, whether with studs or anything from off shore..?

The Studebaker studs are a BIG press fit. They are smooth with no serrations and if I remember right they are .020" larger than the hole they fit into. A much heavier press than most.

Press..????? Put a few large washers on the thread size, then the lug nut and a socket wrench to pull them thru...

OK, but how do you get the old ones out without a press?

Have you tried it with Studebaker studs? True, that will work with most makes serrated studs, but not the Stude ones. Well, without having the hub securly fastened in a big vice and using a large breaker bar with a long piece of pipe for a handle; then you'd probably mess up the threads and have to start over.

It's the Dorman 610-036 I was using and the fit is wrong, says my long-time & trusted machinist. I'll live with left threads before I ruin my hubs.

Over the last couple of months, I have pressed about 20 old studs out, and 20 Dormans. I used a 12T press, and hod no problems whatsoever. I do recall when a local machinist had trouble pressing the old ones out he was not familiar with swaging which Studebaker practiced. I schooled him but do not even bother to use his services for studs anymore, since I now have an easy way to remove the swag. Perhaps yours still has part of the swag in place?

I also noticed when I pressed old studs out of an OEM 56J hub, it had serrated studs, whereas all the others were non-serrated. Further, the 1956 hub had a much cleaner cut around the swag. So I guess quality of parts and labor both began to decline sometime after 1956.

As for clearance, I'd guess there was about .005 interference fit for the studs and holes I dealt with. Just tight enough for the 12T press handle to get firm, but still easy to operate.

Currie Enterprises has a good selection of wheel studs and they have a good variety of sizes, a serrated stud .005 over will press in very easily and be very tight. If the exact size isn't available you can drill the hub to fit. I had used a drill that was .005 under the stud and it pressed in ok.

Why not purchase some NOS Studebaker wheel studs - 196930, then you know you have the correct size?

Just as cheap to order from Stude Intl, I just take an angle grinder, cut mine off, knock em out.
