5 Signs Of Car Suspension System Problems

Suspension systems are classified into different types on the basis of several parameters, including comfort, stability, and handling characteristics. The front and rear suspension in most front-engine front-wheel-drive vehicles is different from those in rear-wheel-drive vehicles and employ different technologies. Typically, the front suspension can be classified into two types: MacPherson strut and Double Wishbone. Meanwhile, the rear suspension varies based on factors such as the presence of a live or solid rear axle, as well as whether the vehicle is rear-wheel-drive or front-wheel-drive.  The most common types of rear suspension systems s are multi link, double wishbone, torsion beam, and MacPherson.

Although you may have different types of suspension systems in your vehicle, you will still experience similar problems when the suspension starts to fail. Understanding the failures of the suspension system before any major problems occurs and having them fixed is necessary for the best vehicle operation, smooth ride, proper handling, and,stability. Here are a few suspension system failure symptoms:

The vehicle experiences a lot of bumps on the road. However, most of this is absorbed by the suspension to ensure that  the passengers do not feel every bump. But when it is all transferred to the cabin and is felt by the driver, it is an indication that the struts or shock absorbers have failed and do not dampen the road disturbances effectively. Experiencing a bumpy ride can mean that there is an issue with the dampening of the bumps, which means that the shock absorbers or struts are failing to do their job. In such a situation, go for a bounce test, to verify if the shock or struts are worn out. Check out how to do the bounce test in the next section.

Suspension alignment is crucial for proper operation. Additionally, the suspension itself could be at fault; a worn-out coil spring might lower one side of the vehicle, creating a load imbalance and consequently pulling the vehicle in a particular direction. Tires, too, could contribute; insufficient tire pressure or uneven tread may yield similar effects.

Another prominent symptom of suspension system failure becomes evident during acceleration, braking, or cornering. If the vehicle squats backward during acceleration, nose-dives excessively during braking, or leans excessively from side to side while turning, it indicates that the shock absorbers and struts have become worn out, resulting in a complete system failure. These indications may also manifest during extreme driving scenarios, such as rapid maneuvers, high-speed braking, or aggressive acceleration. However, if these signs manifest during normal vehicle operation or at low speeds, it could point to a suspension system failure. 

If one of the corners of a wheel is lower than the others, it could suggest damage or wear in that particular spring. Ensure both tires are equally inflated and remove any cargo or loads from the car. If the corner continues to sag, apply your weight to that corner and listen for any sounds from the suspension system, as they may indicate the point of failure.

One of the most dangerous automotive suspension system issues may be the loss of the steering system. If the steering effort is drastically increased at low speeds, or if there is too much play in the steering wheel without any feedback, then there may be a serious steering system problem. This can be a result of low power steering fluid levels, a faulty power steering pump, a leaking steering rack or worn control arm bushings. It is best to have a professional look at the vehicle in case of a steering system failure, as it can have catastrophic results if left unnoticed.

The suspension system controls the overall movement of the vehicle, and any loss in movement can result in accidents due to a lack of control, stability, or handling. To avoid accidents, it is essential to ensure the proper functioning of the suspension system.

Understanding the symptoms brings you a step closer to identifying potential issues with the system, but addressing them is essential for a safe and comfortable drive. Here are several factors that can assist you in evaluating the damage and taking preventive measures to repair the suspension system:

One of the best techniques for identifying shock absorber or strut damage is to conduct a bounce test. The bounce test involves pushing your vehicle’s entire weight down on the vehicle’s bonnet. Release and count the number of times the car bounces. If it bounces more than three times, then there is a problem with your shock absorbers or struts.

A vital method for identifying suspension system failure is by observing how the vehicle reacts after encountering a pothole. If the vehicle is left excessively swaying from the encounter, it presents a clear indication of failure. However, if the vehicle manages to adequately counter the impacts of the disturbance, there might still be life left in your suspension system. While intentionally subjecting the vehicle to this test or performing it at high speeds is not advisable, you should only take note if the vehicle encounters a pothole.

Shock absorbers are filled with oil, which can leak in a damaged shock and serves as an evident warning sign. Conducting routine visual checks of the suspension system can aid in assessing its condition. If shock absorbers or struts appear greasy or oily, there's a significant possibility of fluid leakage, indicating suboptimal functionality. It's important to note that a very thin layer of oil on the shock or strut's surface, where the piston glides, is common and doesn't imply a failed shock or strut. In the case of a leaking strut, you might observe oil escaping from one of the seals or from a hole resulting from damage.

Visual inspections can be valuable for identifying a variety of issues, with rust being one of the most significant concerns, particularly on struts and shock absorbers subjected to prolonged usage. Rust accumulation can eventually lead to leakage.

Listen for clunking, groaning, or bumps, which you may hear or feel. If you hear tapping or ticking on a relatively smooth road, you may have a problem with shock or strut mounts, sway bar links, or sway bar frame bushings. On rough roads or over bumps, clunkiness could indicate worn ball joints or bushings. A loud bang could indicate a problem with the jounce or frame bumpers. With the vehicle stationary, turn the steering wheel left and right. Clicking could indicate a bearing or a tie rod end problem. A groaning sound may point to a power steering or strut bearing problem.

If you are encountering any of the aforementioned symptoms of suspension failure, it is strongly advised that you address the issue either through self-repair or with the assistance of a professional. The suspension system holds vital importance within your vehicle, and possessing a broken or malfunctioning system can significantly impact the overall performance of the vehicle. The effects of a defective shocks or struts are as follows:

• Increased braking distance

• Loss of vehicle stability

• Increased Aquaplaning risk

• Loss of tires' lateral guiding when cornering

• Increased Tire wear

• Reduced ABS and ESP performance
