After removing the spring washer from the car, there was an abnormal noise.
After removing the spring washers (buffer gel/limiting block) from the car, abnormal noises occurred. The main reason is that the metal parts directly came into contact without any buffering, or the suspension geometry changed causing interference or loosening of the components. Immediate restoration or replacement of the corresponding buffer parts is necessary.
Core reasons and phenomena:
Metal direct friction/collision: The spring washers were originally used to isolate the metal contact between the spring and the base, or between the shock absorber body. After removal, during bumps, there would be "clicking", "clattering" or sharp metal friction sounds.
Suspension travel abnormality: The lack of limiting buffering may cause the spring to lose control of its rebound or compress down to collide with the metal tray, triggering resonance noises.
Installation position loosening/misalignment: The original gasket might have filled the gap, and after removal, it led to insufficient preload of the spring seat, top rubber, or pressure bearing during driving, resulting in a loose sound.
Associated component wear exposure: Sometimes, the gasket covered minor noises from aging top rubber or planar bearings, and after removal, the problem became more obvious.
Troubleshooting and resolution steps:
Stop long-distance driving immediately: The absence of suspension buffering will accelerate spring fatigue, damage the shock absorber, and affect driving safety.
Check installation status: Confirm if the spring is accurately aligned and if the tightening torque of the fixing screws meets the standard; if the looseness is caused by the detachment of the gasket, it needs to be re-tightened.
Restore or replace the buffer parts: It is strongly recommended to reinstall the original factory spring washers or replace them with high-quality EPDM rubber buffer blocks of the same specification. Do not run the vehicle without load for a long time.
Check related components: If there are still abnormal noises after restoration, check if the shock absorber top rubber, planar bearing, swing arm ball joint, and rubber sleeve have been damaged due to the absence of buffering impact.
Professional road test detection: Have a technician conduct a test on bumpy roads to distinguish whether it is a simple lack of washers or has caused damage to other components (such as shock absorber leakage, spring deformation).
Special reminder:
Do not misjudge: In some modifications or repairs, some people mistakenly think that "removing the washers makes the car more sporty", but in fact, it damages the original suspension tuning and will definitely cause abnormal noises and reduce safety.
Distinguish sound types: "Squeaking" is mostly due to dry grinding of rubber or lack of lubrication of the bearing; "哐当/咯噔" is mostly due to metal impact or excessive gap； it is necessary to combine the sound characteristics to locate.
If damage has occurred： If the spring breaks， the shock absorber leaks oil， or the tray deforms， simply reinstalling the washers will not solve the problem； it is necessary to replace the damaged assembly.
If you are unsure about the operation procedures， please go to a professional repair shop for handling. The suspension system involves driving safety， and you should not take the risk of trying it yourself.
After removing the spring washers (usually referring to the rubber buffer gel/top rubber of the suspension system) from the car， the shaking occurs because the key buffering and limiting functions are lost， resulting in direct metal hard contact， suspension geometry change， and vibration transmission to the vehicle body. Prohibition of empty driving: Avoid long-distance or high-speed driving until the issue is fixed to prevent damage to the shock absorber housing or causing misalignment of the wheels. If the shaking persists after reinstallation, it is necessary to check whether the shock absorber has failed due to a hard impact (such as oil leakage, damage to the internal valve body) or whether the wheel dynamic balance has been affected.
