Does the shock absorber leak need to be replaced.
Shock absorbers leaking oil usually need to be replaced. A leak from the shock absorber indicates that it has been damaged, and the shock absorption effect will gradually decrease until it loses its shock absorption effect completely. If the shock absorber causes oil leakage due to internal oil seal aging or due to strong impact and other reasons, replacement is necessary. The vehicle shock absorber is the core component of the vehicle vibration filter system, which is responsible for absorbing the vibration and impact caused by the uneven road surface when the vehicle is running, and providing a comfortable driving environment for the driver and passenger. Therefore, once the shock absorber oil leakage is found, it should be checked and replaced in time to ensure driving safety and comfort.
For whether it is necessary to replace one or a pair, it is recommended to replace the shock absorbers on both sides at the same time to ensure the stability and comfort of the vehicle. If it is only a slight oil leak and does not affect the normal use of the vehicle, you can consider continuing to use it and checking it regularly. However, if the oil leakage is serious, especially when the abnormal sound occurs on the bumpy road or affects the driving comfort, it should be replaced immediately.
The same principle applies to the shock absorber of electric vehicles, because electric vehicles also need a good shock absorption system to ensure the smoothness and comfort of the ride.
What does the shock absorber assembly consist of
The shock absorber assembly is mainly composed of shock absorber, lower spring pad, dust jacket, spring, shock absorber pad, upper spring pad, spring seat, bearing, top rubber, nut and other components. It is an important part of the automotive suspension system, which can alleviate shock and shock absorption, improve the stability and comfort of driving.
In addition, the shock absorber assembly can be divided into four parts according to the installation position, the front left, the front right, the back left and the back right, and the position of the bottom lug of each part of the shock absorber (the Angle connected to the brake disc) is different, so the specific part needs to be clear when selecting and replacing the shock absorber assembly.
What are the symptoms of a broken shock absorber
01 Oil seepage
Oil seepage of shock absorber is an obvious symptom of its damage. The outside surface of the normal shock absorber should be dry and clean. Once oil is found to be leaking, especially in the upper part of the piston rod, this usually means that the hydraulic oil inside the shock absorber is leaking. This leakage is usually caused by wear of the oil seal. A slight oil leak may not immediately affect the use of the vehicle, but as the oil leak intensifies, it will not only affect the comfort of driving, but also may produce an abnormal noise of "Dong Dong dong". Due to the high hydraulic system inside the shock absorber, maintenance is a safety hazard, so once a leak is found, it is usually recommended to replace the shock absorber rather than try to repair it.
02 Shock absorber top seat abnormal sound
The abnormal sound of shock absorber top seat is an obvious symptom of shock absorber failure. When the vehicle is driving on a slightly uneven road surface, especially in the 40-60 yard speed range, the owner may hear a dull "knock, knock, knock" drum beating in the front engine compartment. This sound is not a metal tapping, but a manifestation of pressure relief inside the shock absorber, even if there are no obvious signs of oil leakage outside. With the increase of use time, this abnormal noise will gradually increase. In addition, if the shock absorber sounds abnormally on a bumpy road, it also means that the shock absorber may be damaged.
03 Steering wheel vibration
Steering wheel vibration is an obvious symptom of shock absorber damage. The shock absorber contains components such as piston seals and valves. When these parts wear, fluid may flow out of the valve or seal, resulting in unsteady fluid flow. This unstable flow is further transmitted to the steering wheel, causing it to vibrate. This vibration becomes more pronounced especially when passing through potholes, rocky terrain or bumpy roads. Therefore, the strong vibration of the steering wheel may be an alarm warning of oil leakage or wear of the shock absorber.
