Best Prices for Wheel Stud Replacement

Wheel studs are high-strength, threaded steel fasteners that securely hold the wheel and tire assembly to the axle hub. Typically, there are 4 to 6 studs per wheel pressed or threaded into the wheel hub. The wheel and tire assembly is mounted on the hub centering ring and the studs protrude from the hub through the wheel mounting holes. Lug nuts are threaded onto the studs to securely hold the wheel to the hub.

Is it safe to drive with wheel stud problems?

No, but you can temporarily drive a vehicle at low speeds and for short trips with one missing wheel stud. However, if more than two studs are broken, it is recommended to repair the car prior to further use. Having all wheel studs in place with evenly tightened lug nuts prevents distortion of the brake rotor. Over longer periods, missing studs can damage the brake rotor, the wheel, and the remaining studs. A car may vibrate when driving with missing wheel studs and can cause the other studs or lug nuts to loosen. This can lead to the wheel separating from your tire while driving.

Can I drive with a wheel stud problem?

Driving a vehicle missing a wheel lug stud is a bad idea, and can be dangerous. If the car is missing just one stud, you should be able to safely drive it to a repair facility. But don't wait long, as there's an increased chance the other lug studs will fail due to overloading.

How often do wheel studs need to be replaced?

Any time the wheel is inspected or removed, the studs should be checked. Check the back of the hub to ensure the heads of the studs are in good condition.

How is a wheel stud replaced?

On brake rotors with hub assemblies attached, the wheel, brake caliper, its mounting bracket, and rotor assembly would have to be removed before replacing the studs. For sealed wheel bearing and hub assemblies, the wheel, axle nut, brake caliper, brake caliper mounting bracket, brake rotor and CV axle are removed. This provides clearance to remove the hub assembly and replace the wheel studs.

We recommend using OEM or better wheel studs. Wheel studs should be tightened exactly to manufacturer specification every time they are tightened.
