What to Do If the Car Suspension Is Too Hard?
2 Answers
The solutions for a car suspension that is too hard are: 1. Reduce tire pressure to improve ride comfort, but avoid lowering it too much as it can damage the tires and pose safety risks to passengers; 2. Adjust the stiffness of the shock absorbers; 3. Install adjustable shock absorbers; 4. Use seat cushions—excessive stiffness can make passengers feel bumpy and uncomfortable, so car seat cushions can help improve comfort; 5. Break in the shock absorbers; 6. Slow down when encountering bumps, potholes, or muddy roads. The working principle of shock absorbers: When relative motion occurs between the frame or body and the axle due to vibration, the piston inside the shock absorber moves up and down. The oil inside the shock absorber chamber repeatedly flows from one chamber to another through different orifices. The friction between the orifice walls and the oil, as well as the internal friction between oil molecules, creates a damping force that converts the car's vibration energy into heat energy, which is then absorbed and dissipated into the air by the shock absorber.
When I find the suspension is too stiff, I usually first check if the tire pressure is too high, as high pressure can transmit vibrations more intensely. Adjusting the tire pressure to the recommended value in the manual can provide significant relief. Next, I inspect the shock absorbers for any oil leaks or deformities. Older cars often have issues with shock absorber cylinders; if there are oil stains or cracks on the surface upon touching, they need replacement. Tire selection is also crucial—switching to softer tires or slightly reducing tire pressure can absorb more bumps. Driving habits matter too; I avoid sudden acceleration and braking, and I drive slowly over uneven roads to minimize impact. Regular maintenance of suspension components, such as lubricating springs and linkages, can extend their lifespan. Safety should not be overlooked, as stiff suspension may lead to uneven tire wear or chassis damage. Addressing issues early saves trouble.
