Re: Broken Front Wheel Studs
 

Also something to look at is what is piloting the wheel , is it the studs or the id of the rim . Might have a runout problem or the rim moving on the hub when coming down from a wheelstand . I run Strange hubs with screw in 1/2" studs and never have had this problem. Lugs torqued to 65 ftlbs.

Re: Broken Front Wheel Studs
 

I torque my lug nuts to 100 ft lbs front and rear and have never had an issue. Those lug nuts look awfully long, are you sure they are not bottoming out on the hub and not tightening correctly on the wheel.

Re: Broken Front Wheel Studs
 

Just for kicks try calibrating your torque wrench or trying one that is known to be accurate.

Re: Broken Front Wheel Studs
 

Breaks the studs on both sides. Car is not capable of wheelstands...yet.
I looked on Welds website for the torque specs.

I’ll check out what pilots the wheel.

Re: Broken Front Wheel Studs
 

I had to remove the stud from the lug nut with vise grips. It wasn’t handy until it was half way out. Never thought about hub interference with the wheel.

My torque wrench is within 4 pounds of my friends new Snap On wrench. I guess I could lower the torque number a bunch.

Re: Broken Front Wheel Studs
 

What’s your BC measurement on the hub and what is it on the wheel.
Early Ford Mustang Fairlane maverick pinto was 4x4.5” and later fairmont models were 4x108mm (around 4x 4.25”).
Make sure you are using the correct BC on wheel and hub.
Studs have fatigue from a register that’s too loose and allowing it to flex.

The pics of your hub stud hole look rough, was it an original Aero Space hub or modified for a different BC?
Not knocking your equipment.....just imo lol.

Good luck

Re: Broken Front Wheel Studs
 

Plenty of cars out there with Weld wheels and Aerospace brakes, and aren't spitting lug nuts out on the floor. Fit shouldn't be an issue unless parts are made wrong. And unlike axles, front hubs that have the rotors bolted to them don't have a register to center the wheel. Instead they rely on the nuts.

One problem I had with screw in studs in an aluminum hub is the stud backing out of the hub as the nut is torqued. Studs should be torqued into the hub to manufacture's spec (Strange says 65 lb.ft.). I use red lock tight as well. Even doing that they would want to turn. I had to use a socket or tool to hold the head of the stud on the back of the hub while torquing the nut to prevent it.

As has been recommended, I would replace the studs with good USA parts. While talking about length Strange does in fact offer 2 1/2" studs.

Check the hub fit to the wheel center. In the pic of your hub, the inner edge where it transitions to the flat hub looks pretty shiny...like maybe the wheel isn't coming up flat to the flat of the hub.

Re: Broken Front Wheel Studs
 

If the broken stud wasn't free in the lug nut that tells me that the stud was stretching, and staying stretched, past it's strength limits. Better quality studs should help.

Re: Broken Front Wheel Studs
 

From the picture of the hub and the wheel it looks like it has two different bolt circles. It look like you are using the smallest of the two on the hub. Have you tested the wheel to the larger bolt circle. When we used Aerospace brakes the radius on the back side would not let the shoulder of the bolt seat completely. We had to take a .020” cut to fix and still had to observe radius. Good luck.
