How Often Should Car Shock Absorbers Be Replaced?
2 Answers
There is no specific regulation on the replacement interval for car shock absorbers, as it depends on usage conditions and whether there are any malfunctions. Below are the criteria for determining when to replace shock absorbers and the factors affecting their service life: Criteria for replacing shock absorbers: If the shock absorber shows signs of oil leakage, internal buffer rubber aging, cracking, or damage, it indicates a decline in performance, and replacement should be considered. Typically, after 20,000 kilometers, it is essential to thoroughly inspect the condition of the shock absorbers during each maintenance service and replace them promptly if issues are detected. Factors affecting the service life of shock absorbers: The main factors influencing the service life of shock absorbers include road conditions, timely cleaning of dust covers, and regular maintenance.
I've been driving for fifteen years, and my personal experience tells me there's no fixed rule for when to replace shock absorbers. Unlike engine oil, which needs changing every six months, it depends on your driving habits and road conditions. For example, I commute daily in the city on smooth roads, and my shocks are still performing well at 80,000 kilometers. But if you frequently drive on rural roads or encounter potholes on highways, the shocks wear out faster—possibly needing replacement at 60,000 kilometers. The key is to monitor your car's behavior: if it bounces excessively over speed bumps or feels unstable during turns, there's definitely an issue. Delaying replacement of worn shocks not only makes driving uncomfortable but also accelerates tire and suspension wear, increases braking distance, and raises accident risks. During every maintenance check, I ask the mechanic to perform the bounce test—if the car rebounds too slowly or lacks resistance, it's time for new shocks. Generally, urban driving allows for replacement every 7 years, while rural roads demand attention after 5 years. Regular inspections and preventive maintenance are the best strategy—safety comes first, so don't cut corners to avoid bigger problems.
