Why is the Car Suspension So Hard and Bumpy?

Generally, excessive stiffness in the suspension is due to the car being new, as the mechanical components have not yet fully broken in. It is normal for the owner to feel that the suspension is too hard, and it will improve after the break-in period. Additionally, tire pressure should be maintained within the normal range, as excessively high tire pressure can also affect driving stability. Symptoms of damaged shock absorbers: 1. Shock absorber oil leakage: A normal shock absorber has a dry and clean exterior surface. If oil is seeping out, it indicates that the hydraulic oil inside the shock absorber is escaping from the upper part of the piston rod, meaning the shock absorber is essentially failing. 2. Clunking noise from the wheels: When the car passes over bumpy roads or speed bumps, a clunking noise from a particular wheel indicates poor or failed damping performance of the shock absorber on that wheel. 3. Increased body roll: When cornering, a noticeable increase in body roll, or even skidding in severe cases, is mainly due to insufficient damping force from the shock absorber, which fails to effectively suppress the compression of the springs.

The bumpy and stiff feeling is really uncomfortable. When I encounter this issue in daily driving, it's usually because the shock absorbers are worn out or leaking oil. When the fluid is gone, they become stiff and cause the car to bounce. There's also the issue with the springs—if they lack elasticity or are deformed, the car will feel hard and bumpy. Tire pressure being too high is another key factor. High tire pressure makes the tires stiff, and small bumps directly transfer to the car body. I recommend first checking if the tire pressure is within the standard range, then pressing down on the car corners to see how many times it bounces. If it bounces more than twice, the shocks might be done for. Get it checked and replaced at a repair shop as soon as possible, or long-term bumpiness will damage suspension components and tires. Regular maintenance of the shock system, such as checking every 2 years or 50,000 kilometers, can save a lot of hassle.

The car feels extremely stiff and bumpy when driving, as if there's no suspension, which I deeply experienced during long-distance trips. The issue might stem from the tires—excessive air pressure can harden the tread and reduce cushioning. Additionally, worn suspension links or cracked bushings can increase overall rigidity. Vehicle design also plays a role; for example, high-performance models often have stiffer suspensions optimized for smooth roads but perform poorly on rough surfaces. I recommend checking the overall balance, switching to comfort-oriented tires, or slightly reducing tire pressure to alleviate the issue. Also, avoid overloading the vehicle, as excess weight accelerates component fatigue. Drive at a steady speed over bumps to minimize impact. Ignoring these issues long-term can compromise handling and safety, increasing the risk of loss of control. Early intervention is crucial.

The ride is too harsh and uncomfortable, which I believe is often related to shock absorber failure. Damaged oil seals lead to hydraulic malfunction and poor damping. High spring stiffness or deformation is another factor, compounded by improper tire pressure settings. A simple check: press down on the car body when parked to test the rebound; repeated bouncing indicates failure. Rough roads amplify the discomfort, so it's advisable to focus on balancing system maintenance to prevent worsening.
