Understanding Steering and Suspension Systems
Steering and suspension systems are fundamental to vehicle control and ride comfort. They work in tandem to ensure that a vehicle handles correctly while maintaining passenger comfort.
Steering System
The steering system is responsible for allowing the driver to control the direction of the vehicle. Here are the main components:
1. Steering Wheel: The interface through which the driver communicates with the vehicle.
2. Steering Column: Connects the steering wheel to the steering mechanism.
3. Steering Gear: Converts the rotational motion of the steering wheel into linear motion, allowing the wheels to turn.
4. Tie Rods: Connect the steering gear to the wheels and transmit the motion.
5. Power Steering System: Assists the driver in steering by using hydraulic or electric actuators to reduce the effort needed to turn the wheel.
The most common steering mechanisms are rack and pinion, which provides direct feedback and is widely used in modern vehicles.
Suspension System
The suspension system supports the weight of the vehicle, absorbs shocks from the road, and maintains tire contact with the road surface. Key components include:
1. Springs: These absorb shocks and support the vehicle's weight.
- Types of springs include coil springs, leaf springs, and air springs.
2. Shock Absorbers/Struts: Control the oscillation of the springs and help maintain tire contact with the road.
3. Control Arms: Connect the suspension to the vehicle frame and allow for up-and-down movement while maintaining alignment.
4. Ball Joints: Allow for the pivoting of the wheels as they turn and absorb road shocks.
5. Sway Bars: Reduce body roll during cornering for improved stability.
Understanding the intricacies of these components is essential for diagnosing issues and performing repairs effectively.
The Importance of ASE Certification
The National Institute for Automotive Service Excellence (ASE) offers certification for automotive technicians, ensuring they meet industry standards in various areas, including steering and suspension. Here’s why obtaining ASE certification is valuable:
- Credibility: ASE certification is widely recognized and respected in the automotive industry, demonstrating a technician's commitment to professionalism.
- Career Advancement: Many employers prefer or require ASE certification, opening up more job opportunities and potential for higher wages.
- Skill Validation: Certification verifies that a technician has the necessary skills and knowledge to perform complex repairs and diagnostics.
- Customer Trust: Certified technicians often foster greater trust with customers, as they are seen as knowledgeable and qualified.

Frequently Asked Questions
What is the purpose of the steering system in a vehicle?
The steering system allows the driver to control the direction of the vehicle by turning the front wheels.
What components are commonly inspected in a suspension system during an ASE practice test?
Common components include shock absorbers, struts, control arms, bushings, and coil springs.
How can you identify a worn-out tie rod end during an inspection?
A worn tie rod end may produce a knocking noise when turning, show excessive play when wiggling the wheel, and may have visible damage or wear.
What role do struts play in a vehicle's suspension system?
Struts support the vehicle's weight, absorb road shocks, and help maintain proper wheel alignment and handling.
During a steering and suspension test, what is the significance of checking the alignment?
Checking the alignment ensures that the wheels are parallel and properly angled, which helps prevent uneven tire wear and improves handling.
What symptoms might indicate a failing power steering pump?
Symptoms of a failing power steering pump include whining noises when turning the wheel, difficulty steering, and fluid leaks around the pump.
