A wheel stud on a car, also called a wheel bolt or lug bolt, is a threaded metal bolt that protrudes from the wheel hub and extends through the center hole of a wheel. The lug nut is then screwed onto the end of the wheel stud to secure the wheel to the hub. It is typically made of hardened steel to withstand the stress and load placed on it when the wheel is mounted on the vehicle.

The wheel lug stud is responsible for maintaining the wheel's position and preventing it from separating from the car while driving. Car wheel studs also come in a variety of sizes and lengths to fit different types of wheels and hub assemblies. They are typically designed to be replaced if they become damaged, stripped, or worn out.

Wheel lug stud replacement

Replacing a broken wheel lug stud is a fairly straightforward process that can be completed with basic tools. So very first of all, you need to gather all the tools you may need during your wheel stud replacement.

Generally, you will need these tools:

A lug wrench or socket set
Jack and Jack stands
Hammer
Flat washer
A Lug that matches the size and type of the other lug nuts on the wheel
Torque Wrench

When all tools are prepared, you are ready for the replacement. Technically speaking, the wheel lug stud replacement process can involve these steps:

Park the car and loosen the lug nuts by using tools such as a lug wrench or a breaker bar with the correct size socket.
Lift the car with a jack and remove the wheel.
Use a hammer to knock out the broken stud.
Insert the new stud and fully seat it in the hub.
Install a flat washer and lug nut, and tighten until fully seated.
Install the wheel and hand-tighten the lug nuts.
Lower the car and use a torque wrench to tighten the lug nuts.
Repeat for any other broken studs.
Test the car for any issues.

Wheel bolts vs studs, what’s the difference?

Wheel studs and wheel bolts are two different methods of attaching wheels to a car's hub.

Wheel studs are bolts that are pressed or threaded into the hub, but they have a threaded end that protrudes from the hub. The wheel is then placed onto the studs and held in place by lug nuts that screw onto the threaded ends of the studs.

Wheel bolts, on the other hand, are threaded fasteners that screw directly into the hub. They have a tapered end that helps to center the wheel on the hub, and they are tightened with a socket or wrench.

Both wheel bolts and wheel studs are effective methods for attaching wheels to a car's hub, but there are some differences between them. One advantage of wheel studs is that they make it easier to mount a wheel onto the hub because the wheel can be held in place while the lug nuts are tightened. Wheel bolts, on the other hand, can be easier to install because they don't require as much alignment as wheel studs. the choice between wheel bolts and wheel studs depends on the specific make and model of your car, as well as your personal preferences.
