The long drive shaft (propeller shaft) is a rotating component in a vehicle’s drivetrain that transfers power from the transmission or transfer case to the differential.
Main Functions:
1. Power transmission: Transfers engine power from the gearbox to the differential.
2. Torque delivery: Carries rotational force to the driving wheels.
3. Smooth rotation: Helps maintain smooth power delivery while the vehicle is moving.
4. Flexibility: Accommodates slight movements and changes in angles between drivetrain components.
5. Vibration control: Works with universal joints and centre support bearings to minimise drivetrain vibration.
Why Must It Be Replaced?
1 Excessive vibration while driving.
2 Worn universal joints (U-joints).
3 Damaged or bent shaft.
4 Clunking noises during acceleration.
5 Worn centre support bearing.
