What is a wheel stud?
If you look at the wheel hub assembly, you’ll see large steel bolts holding the wheel to the axle hub. These bolts are threaded and secured with a lug nut. There are usually four to six studs for each wheel on your car.
Since the wheel studs keep the wheels on your vehicle, it’s important to get defective, loose, or missing studs replaced as soon as possible.
When should I replace the wheel studs on my car?
The most common symptoms of bad wheel studs include:
A loose wheel: If the wheel studs are wearing out, you’ll notice the tire begin to wobble, vibrate, or loosen while you drive. Get to a tire shop or mechanic as soon as possible since the wheel could break loose from your vehicle.
Missing studs, broken studs, or damaged threads: If you find a broken stud lying on the ground near your vehicle or a mechanic sees that a stud is missing or bent, your vehicle needs new ones. A mechanic might also check the stud threads during maintenance to see if they’re rusted or worn and due for replacement.
A spinning stud during maintenance: If you or a mechanic sees the stud spin in place while fastening the lug nut (during a tire replacement or rotation), it’s a sign that the stud needs to be replaced. They should also check the mounting hole in the wheel hub for damage.
How often should a wheel stud be replaced?
Wheel studs may last the life of the vehicle, so you only need to replace them if they look rusted or damaged.
Are wheel studs easy to replace?
While it seems simple to swap out wheel studs, this is a job best left to the professionals. There’s just too much that could go wrong if you DIY. Plus, you’ll need specialized tools to remove the wheel bearing.
