AUDI A4 Suspension Parts - Online Parts Catalog

The Audi A4 suspension system is designed to provide a balance of comfort and handling, ensuring a smooth ride and precise control. Here's a detailed introduction to the major suspension parts typically found in the Audi A4:

Shock Absorbers (Dampers):These control the movement of the suspension by absorbing and dampening the impact from road bumps. They prevent excessive bouncing and help maintain tire contact with the road.
Struts (MacPherson Struts):Struts combine a shock absorber and a coil spring in one unit. They support the weight of the vehicle and help with alignment. Struts are commonly used in the front suspension of many A4 models.
Coil Springs:These are steel springs that compress and expand to absorb the energy from road irregularities, helping to cushion the vehicle and passengers from bumps and rough surfaces.
Control Arms (Wishbones):Control arms connect the vehicle’s suspension to the frame. They allow for up and down movement while maintaining the wheels' position relative to the body. The Audi A4 often uses multi-link suspension with upper and lower control arms, which improves handling.
Ball Joints:These spherical joints connect the control arms to the steering knuckles. They allow for smooth movement in multiple directions while supporting the vehicle's weight.
Bushings:These rubber or polyurethane components are found at the joints between various suspension parts (like control arms and chassis). They reduce vibration and noise, improving ride quality.
way Bar (Anti-Roll Bar):The sway bar connects the left and right sides of the suspension, reducing body roll during cornering. It helps the car remain level when turning, providing better stability.
Sway Bar End Links:These connect the sway bar to the suspension. They transfer the force from one side of the suspension to the other, reducing body roll during turns.
Tie Rods:Tie rods connect the steering rack to the wheels, allowing the driver to steer the car. They also contribute to the alignment of the wheels.
Wheel Bearings:These allow the wheels to rotate smoothly with minimal friction. They are mounted in the hub assembly and help support the vehicle's weight while reducing rolling resistance.
Steering Knuckle:This component connects the wheel hub, control arms, and tie rods. It plays a crucial role in steering, allowing the wheels to turn while remaining attached to the suspension.
Subframe:The subframe supports the engine, transmission, and suspension components, providing structural integrity. It helps distribute the vehicle's weight and absorb road impacts.
Air Suspension (if equipped):Some Audi A4 models may come with an adaptive air suspension system. Air springs replace conventional coil springs, and the system can adjust the vehicle's ride height and damping settings for different driving conditions.

The Audi A4 uses a multi-link suspension system, which provides enhanced handling and ride comfort by allowing each wheel to move independently. This setup reduces body roll during cornering and improves stability over rough terrain. If you need more specific details on a particular Audi A4 model year or trim, feel free to ask!
