The replacement cycle of the suspension system should be comprehensively determined based on specific operating conditions and component types. For conventional suspension components such as shock absorbers, springs, and control arm bushings, It is best to inspect and replace them every 5 years or 80,000 to 100,000 kilometres under normal driving conditions. If the vehicle is frequently driven on rough roads or carries heavy loads, the replacement interval may need to be shortened to approximately 3 years or 50,000 kilometres. Due to its complex structure, the core components of an air suspension system, such as air springs, shock absorbers, and air compressors, can typically last 5 to 8 years under favorable road conditions. However, prolonged parking or extreme driving conditions will accelerate the aging of rubber components, necessitating replacement as early as 3 years. For daily maintenance, avoid extended periods of inactivity. It is advisable to drive at least 20 kilometres weekly to maintain system functionality. Regularly remove debris from air spring surfaces and inspect their sealing integrity. However, when replacing components, prioritize genuine or certified aftermarket parts to ensure compatibility. Adopting proper driving practices-such as reducing speed over rough terrain and avoiding overloading-can also significantly prolong suspension system longevity.
