Propeller Shaft (Prop Shaft)
The propeller shaft carries torque from the gearbox or transfer case to a rear or front axle.
What is Propeller Shaft (Prop Shaft)?
It is used in rear-wheel-drive and many four-wheel-drive cars. Long shafts are split into sections with a centre bearing. It is balanced to avoid vibration. Shafts are marked for alignment; refitting them in a different position can create vibration. Some modern shafts are made of carbon fibre or aluminium to save weight. Crash-collapsible designs are used in some cars.
How it works
It spins at engine speed divided by gear ratio and transmits torque along the car.
Why it matters for your car
Vibration at certain speeds can indicate imbalance or worn joints. Clunks when engaging drive point to joint wear.
