A driveshaft is like an intermediary between the transmission and the back axle. You’ll only find it in some vehicles like four-, rear-, and all-wheel drive. This video shows how important the driveshaft is. It allows the vehicle to transfer power from the engine to the wheels. Without it, a car would be a fancy paperweight.
If a vehicle vibrates like a jackhammer on steroids, the driveshaft may’ve gone bad. It won’t exactly be the smooth ride you were hoping for. Besides, abnormal noises are never a good sign. There shouldn’t be any clunks, rattles, or even a bad sound when switching gears. Otherwise, it’s time to pay attention.
Also, turning the car shouldn’t feel like a wrestling match. If there’s trouble making those turns, it could be another symptom of a failing semi truck driveshaft. No driver wants to get stuck doing three-point turns in the middle of traffic. Another sign of a faulty driveshaft is a transmission fluid leak.
It’s vital to consult a mechanic to prevent further damage. Driveshaft replacement can cost between $300 and $800 for rear-wheel-drive cars. And that’s not all. An extra $150 to $200 for labor may be necessary. But it’s better to fix it than let the problem worsen and burn a hole in the pocket later.
Regular inspections are key. Experts recommend inspecting the driveshaft for cars, light trucks, and buses at least once a year. A heavy-duty vehicle may need checks every six months.
