Everything You Need to Know About Suspension Systems In Automobile

Every automobile type has a system to separate the wheels and other components of the vehicle from the car’s body. This system’s main purpose is to provide enhanced comfort while riding in the vehicle. The suspension system in automobile is essential for controlling the ride which means the suspension system works to control the vertical movement of the vehicle’s body. Regardless of whether you’re driving down a motorway, through the streets of a major city, or rugged roads, the vehicle is guaranteed to be in full control at all times. If you’ve ever asked, “What are the 4 types of suspension system?”, “How does a car suspension system work?” or “How do I know if my suspension needs replacing?” This article is intended for you.

What Does Suspension System Mean?

The system, commonly referred to as suspension system, includes a strut, springs, dampers (or shock absorbers), control arms and so on. These parts work as one to provide support to the vehicle’s weight and to also absorb movements which aids in correcting imperfections on the road.

What Are the 4 Types of Suspension System in Automobile?

1. Independent Suspension

With independent suspension, a vehicle has the ability to control each wheel independently to provide maximum comfort and comfort. This is often used in modern automobiles.

Front Independent Suspension This is predominantly found in most cars where it is used to enhance the stability and steering of the vehicle.

Rear Independent Suspension Used mostly in performance cars, luxury vehicles and high end cars in order to provide a much smoother ride.

2. Rigid Axle Suspension

This system joins the wheels via one rigid axle. It is mostly found in heavy-duty vehicles such as trucks and off-road SUVs. 

Benefits: High durability concerning a rigid structure and great ability to manage heavy loads. 

Downsides: Uncomfortable due to its rigid structure. 

3. MacPherson Strut Suspension

This is one of the most recognized types, especially on the budget and midrange cars because of its straightforward structure and having an affordable price. 

Benefits: Very cheap and light. 

Downsides: Have reduced high-performance handling compared to multi-link suspensions. 

4. Multi-Link Suspension

A more advanced system with a higher range in pricing can usually be found in sports cars, giving out great handling and comfort. 

Benefits: Great shock absorbing stiffened body and exceptional cornering grip. 

Downsides: Difficult and costly to maintain. 

How Does a Car Suspension System Work?

The suspension system consists of components which help maintain the contact between the tires and the roads within certain limits of shocks and vehicle movements and here’s how it works: 

Springs are the shock absorbers – In response to the road springs, whether leaf or coil, compress or expand in order to absorb impacts. 

Shock absorbers help control movement – Bouncing needs to be controlled, dampers are used to dissipate energy keeping bounce within limits. 

Control arms and linkages maintain alignment – While the wheels are free to move out and align smoothly, these parts ensure that the wheels are in a fixed position.

Bushings and mounts dampen noise and vibration – They buffer minor imperfections in the road.

Collectively, they contribute to increased acceleration, better handling and provide a smoother ride.

How Do I Know My Suspension Needs Replacing?

A poorly working or failing suspension system will put your car at risk. Here are some of the most common indicators:

‘Cupped’ tyres – One way or excessive characterisation of your suspension issue.

Continued bouncing – Car continues to bounce even when the bump has already been cleared. This suggests that the shock absorbers need replacing.

Drifting – Inability to drive in a straight line.

Sounds – Driving over a bump exaggerates noises, suggesting that there are low-quality suspension components.

Twisting dive – The front of your vehicle nose dives hard when it stops and the vehicle softens quickly.

Hard to steer – The car is unstable and hard to steer.

If you experience any of the above symptoms, it’s best to consult with your trusted mechanic and have your suspension examined.

How Much Does It Cost to Replace the Suspension System? 

With the United Kingdom’s suspension costs, the replacement price’s accuracy is determined by a range of factors such as the vehicle type, suspension design and labor charges. 

Average Suspension Replacement Costs in The UK: 

Shock absorber replacement: £150 – £400 per pair. 

Spring replacement: £100 – £300 per spring. 

Strut assembly replacement: £300 – £800 per strut. 

Full suspension system replacement: £1,000 – £5,000 depending on the model of the car. 

Factors that Affect the Costs: 

Suspension systems for sports and luxury vehicles tend to have a higher market price, making it more costly than it usually is. 

OEM vs. aftermarket parts: Parts manufactured by Original Equipment Manufacturer (OEM) have a higher value than parts manufactured by other companies. 

Should You Repair or Replace the Suspension? 

Replacing the shock absorbers or springs is definitely a more cost effective option when trying to repair specific vehicle parts. Replacing the entire system is also an effective solution if the components have high wear. 

To try to avoid expensive repairs and prolong the lifespan of your suspension, make sure to follow proper maintenance procedures. 

Make sure to frequently inspect the components that make up the system for any signs of damage.

Properly inflating your car tires will place less strain on the suspensions.

Whenever you can, try to avoid potholes and bumpy roads.

Make sure you do wheel alignments and balancing to ensure proper tension is placed on the suspension system.

Address unusual sounds early to prevent further steeping issues.

Conclusion

Being familiar with the workings of the suspensions system, as well as when to be most alert, will improve your overall driving experience. This is particularly relevant when you are looking for answers in the UK on questions like “How do I know if my suspension system needs replacing?,” “How does a suspension system work in a vehicle?,” or “What are the four suspension systems?” and other related queries.
