You can travel comfortably thanks to your car’s suspension system. To keep you more comfortable in the driver’s seat during road humps and dips, a system of shock absorbers, struts, and springs is used. But in addition to providing a comfortable and effective ride, your suspension system also contributes to the overall health and durability of your car.
A car’s suspension is a system that manages the vehicle’s height. It is one of the crucial components that contribute to maintaining the comfort level in the car by minimizing or eliminating the shock when driving.
In this article, we are going to be talking about everything concerning the service suspension system.
What is the car’s suspension system?
The shock absorbers, coil springs, struts, leaf springs, and tires are just a few of the main parts that make up the suspension system. Your tires are part of the suspension system!
Long, tube-shaped pistons known as shock absorbers are sometimes also gas- and liquid-filled. By compressing and extending, they support the springs and lessen the force of a bump or dip in the road.
A large portion of the impact from potholes and ruts in the road is absorbed by coil springs, which are located close to the shock absorber.
Although it is crucial for ride safety, suspension is not just about comfort. A sufficient amount of braking power is always provided by the suspension, which keeps all four wheels firmly planted.
Furthermore, by moving the center of gravity of the car, it maintains the car upright and under control when cornering, especially at high speeds.
A large portion of the impact from potholes and ruts in the road gets absorbed by coil springs, which are located close to the shock absorber.
The shock absorber and spring are combined into one component in struts. For the support of your car’s frame, use struts. Struts are not a standard feature on all cars, and when they are, they are usually just on one axle.
Metal plates with a little curvature are clamped together to form leaf springs. They are primarily seen on cars with solid rear axles and are fitted to automobiles to help reduce vertical vibration.
Only the tires in your car’s suspension system make contact with the ground. Most of the impact from road dips and bumps is absorbed by your tires before being transferred to the shocks and/or struts
Symptoms of a bad Suspension system
A worn-out shock or strut can no longer efficiently deflect the force of bumps and other road imperfections, which makes the ride unpleasant or bumpy. Additionally, this may result in the car bouncing too much, which makes it challenging to maintain stability and control.
Unbalanced tire wear
Uneven weight distribution on the tires, which results in uneven tire wear, can be brought on by a malfunction with the suspension system. This may result in the tires developing bald areas or other wear indicators, which may decrease traction and create a potentially hazardous driving situation.
Differing from or pulling to one side
It can be challenging to keep control of a moving vehicle, which increases the risk of collisions. The wheels may be out of alignment, which would impair steering, and this might come from worn-out or damaged control arms or ball joints.
Due to severe body roll or sway during turns caused by a damaged or broken sway bar link, the car may be unsafe and challenging to manage. During quick lane changes or sharp corners, this may be more obvious.
Audible Suspension System Noise
An issue with one of the parts, such as worn-out ball joints or control arms, can be detected by a clunking or knocking sound emanating from the suspension system. Additionally, this can mean that the suspension system is not securely fastened or is loose, both of which could result in additional damage and potentially hazardous driving situations.
The Dashboard’s Warning Light
The onboard computer of the car has identified a problem with the suspension system if the “service suspension system” warning light illuminates on the dashboard. This warning needs to be taken carefully since it may reveal a potentially hazardous driving condition that needs to be resolved right now.
Causes of a Bad Suspension System
Suspension parts are worn out
Components of the suspension system may become ineffective and worn out over time. This may lead to instability in the suspension system and the appearance of the “Service Suspension System” alert.
Suspension system leakages
Leaks in the suspension system can be caused by damaged shocks or struts, for example. The “Service Suspension System” alert may appear as a result of pressure loss from this.
Modern automobiles have sensors in the suspension system that can spot any irregularities. The vehicle’s onboard computer may receive misleading signals from a defective sensor, which may result in the “Service Suspension System” alert.
The performance and lifetime of the suspension system depend on proper maintenance. The suspension system may experience problems if the manufacturer’s advised maintenance plan is not followed.
The Suspension System Has Been Damaged
The “Service Suspension System” warning may appear if damage to the suspension parts, such as by running over a pothole or curb, results in problems with the suspension system.
The “Service Suspension System” notice could occasionally come from an electrical fault, like a blown fuse or a wiring issue.
How Can A Service Suspension System Be Reset?
Finding the root of the issue is the first step in fixing a service suspension. The malfunctioning system could be activated for many reasons, such as an incorrect air shock, a broken airline, or a ride height sensor, among others.
Let’s go over some of the fundamental actions that must be taken to properly work on the suspension in a car because the service suspension system needs to be reset.
Turn off your car.
Shutting down your car is the first thing you should do when a problem arises to avoid serious harm or injury. The trunk-release switch is located on the driver-side door panel’s bottom. Push the trunk release switch, which is located on the driver-side door panel’s lower portion.
Action must be taken as soon as the problem starts. Otherwise, the issue with the car can become more serious.
Approach the vehicle’s rear and open the trunk
It would be advisable to continue with the rear or back of the vehicle at this stage. Examine all the alterations or damage in this area, and if possible, make the necessary repairs or seek professional advice. After all, it’s a crucial task to complete on your own because it involves several wires and circuits.
And because we can’t afford to start over without correcting the previous issue, you must carry out all of these actions cautiously and methodically by opening the trunk.
Switch Off the In-Service Suspension System by pushing it.
The following step is to turn off the air suspension system after coping with and finishing the aforementioned procedure. The switch, which is in charge of turning on and off the suspension system, is often found on the kick plate on the floorboard on the passenger side.
Make certain the switch is in the on position before beginning the procedure. The check air suspension light on vehicles is most frequently caused by the air compressor not working properly or at all.
Turn the In-Service Suspension System on.
The switch that you first turned off in the previous step must now be switched on; this is the final step. As previously indicated, the process for turning on is very similar to that for turning off.
As a result, your duty is finished at this moment, and you will get to where you want to go. The solution will come if you carefully and progressively carry out each procedure, one at a time.
With every bump, the car’s suspension system functions as a shock absorber. If the car is no longer absorbing the shock from dips and bumps, suspension repair services could be necessary to guarantee the safety of your vehicle.
