Driveshaft
The driveshaft is the spinning shaft that sends power from the transmission to the rear or all wheels in many vehicles. When its joints or bearings wear out, you may feel vibration, hear clunking, or notice shuddering when you accelerate. Repairing or replacing it restores smooth, reliable power to your wheels.

Frequently asked questions
What are the signs of a bad driveshaft?
The most common signs are vibration that increases with speed, clunking when shifting or accelerating, and a squeaking noise. These usually mean worn joints or bearings.
Can I drive with a bad driveshaft?
It's risky. A failing driveshaft can break loose while driving and cause serious damage or loss of control, so it should be inspected and repaired quickly.
Do you replace the whole driveshaft or just the joints?
It depends on the damage. Often we can replace just the worn U-joints or center bearing, but a bent or badly worn shaft needs full replacement.
