* Driveline problems. A worn-out driveshaft, misaligned wheels, or damaged transmission could also be the culprit.
* Suspension issues. Worn-out shocks or struts, broken coil springs, or bad ball joints could all cause the steering wheel to vibrate.
* Brake issues. A warped brake rotor or a stuck brake caliper could cause vibrations in the steering wheel.
* Tire problems. Uneven tire wear, underinflated tires, or a damaged tire could all cause the steering wheel to vibrate.
If you are experiencing vibrations in the steering wheel when sitting at a stop light, it is important to have it checked out by a qualified mechanic as soon as possible. This could be a sign of a serious problem that needs to be addressed immediately.
