View Full Version : Front Wheel Studs length
04-01-2017, 12:16 PM
Hello, can anyone tell me the length of the wheel bolts on the front axle? And are there some longer available? I need 15mm (approximatly 0,6 inch) more. Or maybe convert to nuts in the drum and fix the wheel with bolts.
The reason is because i have to put spacers on.
Thanks for your answers!

Markus, these wheel studs are available at many places. Here is one CLICK HERE (http://www.macsautoparts.com/ford_thunderbird/ford-thunderbird-wheel-stud-frt-and-rr-wheels-w-drum-brakes-1-2-20-x-1-5-8-1958-79.html)
Your car was made using 'inch' sizes and the wheel studs are 1/2" in diameter with 20 threads per inch. The standard length is 1-5/8" (or 41.275mm long). The same studs are used on the front and rear. They can be removed by knocking out with a hammer. To install, simple enter the stud from behind and use the nut to draw the stud all the way home.
Extra long studs are available. - Dave

Dave, thank you vergessen mich!
Do you have me a hot tip where to find longer versions of the studieren?

I also had to add some 1/4" spacers on the front, and thought this would be a no brainer. A month later I was still fighting it. The problem I ran into, was the knurled part of the new studs was always a loose fit in the hub and instead of pressing in, they just fell in. I tried several manufacturers and they were all the same. I know, you're thinking the holes in my hubs must be oversized. Nope. I even called the tech team on the stud manufacturer and they gave me the specs. What they quoted me, easily allowed the knurled section to be undersized with their plus/minus tolerances. I tried Dorman 610-444, Dorman 610-519 and Wagner BD125969. I also tried a set I found at Pep Boys and they had the same loose fit. To make a long story short, I ended up with studs from Summit Racing that were Moser MSR-8010 (1/2-20X3", RH thd, .625" knurl). I ended up putting a nut on the studs and cutting them to length. That worked fine. Another option is the MSR-8250 which is 1.938" in length. Not quite long enough for me since I wanted to make sure I had a full nut on the stud. It was very close though. Believe me, I never thought changing studs would be this much of a challenge. Good Luck

Those of us who retrofit front disk brakes end up with two drums we can no longer use, both loaded with studs. I have pounded out a few and used them. - Dave

Nyles, thanks a lot!
I have just ordered the studs, these are exactly that what i need.

The studs are delivered!
The next issue is to push them out. Could anyone tell me a trick how to solve? I have a 5T press, but during pressing the drum deform a little bit and I stopped further pressing. Should i have to heat the drum up?
Thanks and regards

On the front drums, the center hub can be removed from the drum. The brake drum registers on the machined center fit and can get tight from rust etc. A little WD40 or heat usually helps to get it to release. This makes it a lot easier to press out the studs as you can use a large socket or pipe as a backup when pressing the stud.
I would also recommend cutting the studs to length prior to installing them. It's a lot easier

You're making this job much harder than it should be. Broken or short studs DO NOT need a press on either the front hubs OR rear axle flanges. A simple hammer blow or two will send the old stud right out the back.
A press is the worst tool to use.
The studs have a swage that simply stops the stud from turning in the round, smooth hole. It's not a precision press fit but it works because those little lines in the stud are designed to upset (fold over) as the friction becomes greater. - Dave
