Types of Car Suspension

Car suspensions provide a connection between the vehicle and the wheels. There are various types of car suspensions. Below are some of them:

• Independent suspension

This suspension allows the wheels to move up and down independently without affecting each other. It provides a better grip and smoother ride on uneven roads. There are four types of independent suspensions:

• Double wishbone suspension: This is the most advanced suspension. It is used in sports cars because it is light and offers good handling and performance. It is also more expensive.
• MacPherson strut: This is the most common type of suspension. It is simple and cheap to manufacture. It is used in most cars and provides a more compact design.
• Multi-link suspension: The multi-link suspension offers a balance between comfort and performance. It is used in most vehicles.
• Transverse leaf spring suspension: This is an independent suspension that uses a leaf spring. It is used in heavy commercial vehicles.
• Dependent suspension

These suspensions connect the wheels on the same axle. When one wheel moves, the other wheel on the same axle moves together. This affects the comfort and traction of the vehicle. There are two types of dependent suspensions:

• Torsion beam suspension: This is the most common dependent suspension. It is used in most small and compact vehicles. The suspension is compact and lightweight.
• Semi-elliptical leaf spring suspension: This suspension uses leaf springs. It is mostly used in heavy-duty or commercial vehicles.

Specification and maintenance of car suspension

• Regular inspection

It is important to conduct routine inspections of the suspension system for signs of wear, damage, or leaks. This includes checking the shocks for car for oil leaks, examining the suspension components for cracks or rust, and ensuring all fasteners are securely tightened. Any issues should be addressed promptly to prevent further damage and maintain optimal suspension performance.

• Wheel alignment

Proper wheel alignment is crucial for even tire wear, vehicle stability, and optimized suspension performance. It should be checked periodically, especially after hitting a pothole or curb, to ensure the wheels are correctly angled and aligned according to the car manufacturer's specifications.

• Tire pressure

Maintaining the correct tire pressure is important for the suspension system. Proper inflation ensures even weight distribution, stability, and optimal shock absorption. Drivers should check the tire pressure regularly and adjust it according to the manufacturer's recommendations.

• Load capacity

Exceeding the car's load capacity can strain the suspension and cause premature wear. Drivers should follow the manufacturer's recommendations for the maximum load capacity. For vehicles with frequent heavy loads, like trucks, consider upgrading to heavy-duty carlisle suspension components.

• Driving habits

Aggressive driving, such as speeding over bumps or potholes, can strain the suspension. Drivers should adopt smooth driving habits, such as avoiding sudden stops, accelerating gently, and reducing speed over rough terrain to reduce strain on the suspension system.

• Fluids check

For vehicles with steering fluid or shock absorber fluid, it is important to check the levels periodically and top up to the specified level. Also, check for any leaks and address them immediately to prevent suspension component damage and ensure optimal performance.

• Replacing worn components

Over time and mileage, suspension components such as bushings, ball joints, and tie rods will wear out. When this happens, it is important to replace them with parts that meet the specifications of the original equipment to ensure proper suspension function and safety.

How to choose car suspension

• Consider the vehicle type

When choosing a struts car suspension system, consider the type of vehicle. The car suspension system for a truck is different from that of a sedan. The suspension system of a truck is designed to carry heavy loads. It is more robust and durable. A sedan has a standard suspension system. The type of vehicle to be fitted with a suspension system will determine the type of suspension to be used.

• Check the compatibility

When selecting a suspension system, ensure that it is compatible with the vehicle. Check the model and year of the car to ensure that the suspension system is compatible. A compatible suspension system ensures easy installation, and it operates effectively. Additionally, it reduces the risk of damage to the car.

• Weight capacity

Consider the weight capacity of the suspension system. This is because different suspension systems have different weight capacities. For instance, a suspension system for a truck will have a higher weight capacity than that of a sedan. The suspension system's weight capacity should be able to support the load of the vehicle. Overloading the suspension system can cause damage to the vehicle and reduce its performance.

• Driving condition

Consider the driving condition when choosing a suspension system. The car suspension system for off-road is different from that of a road car. An off-road car requires a heavy-duty suspension system that can withstand rough terrain. On the other hand, a vehicle that is driven on smooth roads requires a standard suspension system.

• Budget

Set a budget when choosing a car suspension system. Compare the prices of different suspension systems. Be cautious of very cheap suspension systems, as they may be of low quality. Look for a suspension system that offers value for money.

• Performance

Consider the performance of the car when selecting a suspension system. A good suspension system improves the performance of the car. It offers stability and comfort when driving. Additionally, it enhances the handling of the car.

How to diy and replace the car suspension

Replacing a car suspension can be complex and time-consuming. It is advisable to have a professional mechanic to replace the suspension when a vehicle owner finds it challenging. However, for those who feel they can do it, here is a guide on how to DIY and replace a car suspension.

Car owners should understand that replacing a car suspension requires a high level of mechanical expertise and the right tools. It is advisable to consult the vehicle's service manual before starting the process. Below are the general steps to follow when replacing a car suspension.

• 1. Ensure the car is parked on a flat surface and engage the parking brake.
• 2. Chock the wheels to prevent the car from moving.
• 3. Loosen the wheel lug nuts.
• 4. Raise the vehicle using a jack and place it on jack stands.
• 5. Remove the wheels once the car is on jack stands.
• 6. Locate the suspension components that need replacement.
• 7. Using the appropriate tools, loosen and remove the bolts connecting the auto shocks or shock absorbers to the control arms and knuckles.
• 8. Once the old suspension parts are removed, clean the mounting points.
• 9. Install the new shocks, struts, or coil springs, ensuring the orientation is correct.
• 10. Hand-tighten the bolts initially, and then torque them to the manufacturer's specifications.
• 11. Reinstall the wheels and lower the vehicle to the ground.
• 12. Torque the wheel lug nuts to the specified value.
• 13. Conduct a test drive and listen for any strange noise.
• 14. Inspect the suspension components after driving for a short distance to ensure they are properly installed.

Q and A

Q1: What is the purpose of a car's suspension?

A1: A car's suspension serves several key functions, including:

• Maintaining tire contact with the road surface, which improves handling and braking performance
• Minimizing the impact of bumps and road imperfections on the vehicle, providing a smoother ride for occupants
• Supporting the vehicle's weight and load-carrying capacity
• Enabling the vehicle to corner effectively by reducing body roll

Q2: What are the signs of a suspension problem?

A2: Common signs of suspension issues include:

• Uneven tire wear
• Pulling or drifting to one side
• Nose diving during braking
• Excessive body roll during cornering
• Visible damage such as leaking shocks or broken springs

Q3: How often should the suspension be checked?

A3: While there is no fixed interval, it is recommended to have the suspension inspected during routine maintenance services. This could occur around every 30,000 to 50,000 miles. The frequency may vary based on road conditions and driving habits.
