How to Deal with Overly Stiff Shock Absorbers?
2 Answers
Methods to address overly stiff shock absorbers can be divided into the following three scenarios: 1. Break-in period for new cars: Generally, excessive stiffness in shock absorbers is due to the vehicle being new, and its components not having fully broken in yet. During this time, the sensation of overly stiff shock absorbers is normal, and it should improve after the break-in period. 2. Reduce tire pressure: The stiffness of the shock absorbers can be adjusted by altering the tire pressure. However, the reduced tire pressure should remain within the normal range. This method can provide slight relief. 3. Upgrade to adjustable shock absorbers: Consult with professionals and, if modifications are permitted, replace the current shock absorbers with adjustable ones that allow for hardness adjustment, such as coilover shock absorbers, which can also adjust height and damping.
I find that stiff shock absorbers are quite common, usually due to aging or design issues with the dampers themselves. Once the hydraulic oil inside the shock absorber becomes too thin or leaks, the damping effect deteriorates, making the ride feel bumpy and uncomfortable, especially when driving over potholes. Excessive tire pressure is also a major factor. The standard tire pressure is usually listed on the door frame, and adjusting it to the recommended value can significantly improve the ride. If the inspection reveals that the shock absorber is faulty, it's advisable to replace it with a new one. There are softer models available on the market, but avoid buying cheap, off-brand options to prevent compromising handling or safety. If the factory shocks on a new car feel too stiff, it might be due to a sportier tuning. Over time, drivers may adapt, but prolonged use of stiff shocks can accelerate wear on suspension components, so it's recommended to have a mechanic check them during regular maintenance.
