While it is technically possible to drive a vehicle with a damaged suspension system, it poses serious safety risks and may violate traffic regulations. Suspension failures can cause uneven tire wear, uneven stress on the wheel hubs, accelerate damage to other components, and in extreme cases, lead to loss-of-control accidents. According to technical analysis, common faults such as shock absorber oil leakage or ball joint wear significantly reduce vehicle stability, especially when driving at high speeds or on curves, where the risk multiplies. Legally, although there is no explicit prohibition on driving a faulty vehicle, if an accident occurs as a result, the insurance company may refuse compensation on the grounds of "failing to maintain the vehicle in a roadworthy condition". In terms of maintenance costs, ignoring initial suspension issues can lead to a surge in subsequent repair costs. For example, replacing a single shock absorber costs approximately 800-1500 Malaysian ringgit, while repairing associated damaged suspension arms or bearings can cost more than 3000 Malaysian ringgit. It is recommended to immediately conduct professional testing when symptoms such as abnormal noise, body tilt or abnormal bouncing are detected. Usually, the diagnostic fee for the suspension system is between 80-150 Malaysian ringgit, which is far lower than the potential loss from an accident.

Replacing car suspension components is a technical task that requires professional knowledge and tools. While it is theoretically possible to do it yourself, you need to carefully assess your own capabilities. The suspension system directly affects driving safety and comfort. The installation of components such as shock absorbers and springs must be carried out strictly in accordance with the torque specifications and sequence stipulated by the manufacturer. For example, the piston rod of the shock absorber must be installed vertically upward; over-tightening or under-tightening the bolts may lead to potential safety hazards. In actual operation, professional tools like spring compressors are required to avoid injuries caused by spring elasticity. Additionally, a four-wheel alignment test must be performed after replacement to prevent abnormal tire wear or vehicle deviation. It is recommended to choose accessories from well-known brands such as KYB to ensure quality. However, if you lack experience, it is best to leave it to professional technicians, as suspension maintenance involves adjustments to vehicle dynamics. Improper operation may cause abnormal noises, unstable handling, or even component damage. When considering DIY replacement, you need to weigh the costs against the risks. Usually, the installation fee ranges from 300 to 500 Malaysian Ringgit, while professional maintenance provides warranty coverage.

When the car's suspension system malfunctions, it can be repaired, but the specific repair method depends on the type and severity of the fault. Common suspension system issues include ball joint wear, shock absorber oil leakage, strut mount abnormal noise, sway bar bushing wear or loose connection parts. These problems can usually be resolved by replacing buffer rubbers, control arm assemblies, shock absorbers, strut mounts or tightening screws. If the fault involves the air suspension system, check the air pump or conduits for leaks. Note that most suspension components are precision parts, making repairs relatively difficult. It is recommended to choose a regular repair shop and use original factory parts for replacement to ensure safety and durability. Although the vehicle can still drive briefly with a faulty suspension, it will cause problems such as uneven tire wear and uneven wheel load, which may lead to more serious consequential damage. Therefore, immediate inspection and repair should be conducted when abnormalities are detected. For vehicles still under warranty, as long as maintenance meets the manufacturer’s standards and there is no man-made damage, warranty services—including coverage for major suspension components—are available even if maintenance is not performed at a 4S shop. Repair costs vary by vehicle model and damage severity: replacing ordinary suspension parts costs approximately several hundred to several thousand ringgit, while air suspension system repairs may be more expensive.

Suspension system maintenance primarily involves the inspection and replacement of components such as shock absorbers, suspension arms, ball joints, and connecting rods. When a vehicle exhibits abnormal noises, deviation during driving, or reduced damping performance, targeted repairs are typically necessary. Specific procedures include replacing leaking or failed shock absorber assemblies, repairing worn lower control arm ball joints and rubber bushings, adjusting the tightness of suspension links to restore geometric parameters, and replacing suspension springs or bushings as needed. Additionally, post-repair four-wheel alignment calibration is essential to ensure parameters like wheel camber and toe angle meet specifications, preventing abnormal tire wear. Notably, rubber components in the suspension system (e.g., bushings and dust covers) deteriorate and crack over time. It is recommended to inspect them every 60,000 kilometers or 5 years. After driving through water during rainy seasons, promptly clean chassis sediment and lubricate metal joints to prolong component lifespan. Maintenance costs vary by vehicle model. For standard family cars, replacing a single shock absorber typically costs between 800 to 1,500 ringgit, including labor charges.

The time required for car suspension repair usually depends on the extent of damage and the type of repair. A standard suspension repair (such as replacing shock absorbers or springs) takes approximately 2 to 4 hours at a professional repair shop. If complex systems like multi-link or air suspension are involved, it may take half a day to a full day. The repair time is also affected by parts availability; if genuine parts need to be ordered, the process may be extended by 1 to 3 days. For a conventional MacPherson suspension, a skilled technician can complete a single-side replacement within 3 hours, while 4S shops may take slightly longer due to standardized procedures but offer greater reliability. Air suspension repairs for high-end models typically require 6 to 8 hours or more due to necessary system calibration. Car owners are advised to schedule appointments in advance and verify parts availability to prevent delays. Prompt suspension system repairs are critical as they directly impact driving stability and ride comfort, while regular inspections can help prevent unexpected failures.
