axle is a crucial mechanical component that connects the wheels to the vehicle and supports the weight of the car. It also plays a vital role in transmitting power from the engine to the wheels (in driven axles), enabling movement.

Types of Car Axles:

1. Front Axle
   • Located at the front of the vehicle.
   • Supports steering and absorbs shocks from road bumps.
   • In front-wheel drive cars, it also delivers engine power to the front wheels.
2. Rear Axle
   • Located at the rear.
   • Transmits power from the differential to the wheels.
   • In rear-wheel drive cars, it is the main driving axle.
3. Stub Axle
   • Connected to the front wheels.
   • Supports the wheel hub and allows the wheels to turn.

Types Based on Function:

• Live Axle: Delivers power to the wheels (driven axle).
• Dead Axle: Does not rotate or deliver power, only supports weight.

Materials and Durability:

Axles are usually made from forged steel or alloy steel for strength and durability. They must withstand torque, vehicle weight, and road impacts.

Key Functions:

• Bearing the vehicle’s weight
• Assisting with steering (front axle)
• Transmitting power (driven axles)
• Maintaining proper wheel alignment and spacing
