Overview of the Front Suspension System
The front suspension system of the 2004 Infiniti G35 sedan plays a crucial role in ensuring a smooth and stable ride. It is responsible for supporting the vehicle's weight, absorbing shocks from the road, and maintaining tire contact with the pavement. The main components of the front suspension system include:
- Struts
- Control arms
- Ball joints
- Sway bar (stabilizer bar)
- Springs
- Tie rods
- Wheel hub assembly
Understanding how these components work together is vital for diagnosing issues and performing repairs.
Key Components of the Front Suspension System
1. Struts
Struts are a critical part of the suspension system, combining shock absorption and structural support. They help maintain the alignment of the wheels while providing cushioning for the vehicle. The 2004 Infiniti G35 sedan uses MacPherson struts in the front suspension, which allows for a compact design and efficient space usage.
2. Control Arms
Control arms connect the vehicle's chassis to the wheels, allowing for controlled movement during suspension travel. The G35 sedan features upper and lower control arms, which not only support the weight of the vehicle but also help maintain proper wheel alignment.
3. Ball Joints
Ball joints serve as pivot points for the control arms and the wheel hub assembly. They allow for smooth movement and flexibility while also maintaining stability. Regular inspection is essential, as worn ball joints can lead to alignment issues and uneven tire wear.
4. Sway Bar
The sway bar, or stabilizer bar, helps reduce body roll during cornering. It connects the left and right sides of the suspension system, ensuring that when one wheel rises or falls, the other side is affected, promoting balance and stability.
5. Springs
Coil springs in the front suspension help absorb shocks and maintain ride height. They compress and expand as the vehicle encounters bumps and dips, providing a smoother ride for occupants.
6. Tie Rods
Tie rods connect the steering mechanism to the wheel assembly, allowing for precise steering control. They play a significant role in ensuring proper alignment and handling of the vehicle.
7. Wheel Hub Assembly
The wheel hub assembly houses the wheel bearings and provides a mounting point for the wheels. It is essential for ensuring smooth wheel rotation and supporting the weight of the vehicle.
