shock absorbers are connected to the vehicle body and suspension parts. They are utilised to null out ground vibration, giving a smooth ride. Most new vehicles and trucks generally have shock absorbers at all four wheels.
Shock absorbers are essentially tube shaped holders loaded up with gas or fluid. They are mounted from the suspension to vehicle frame. When you drive over a knock, the cylinders inside the shock absorbers push and contract against the fluid or gas.
Shock absorbers undergo a huge amount of stress, particularly on rough streets. The gas or fluid will in the long run spill, bringing about a shaky or rough ride. With worn shock absorbers, it is conceivable that the tires could lose contact with the street as well as erode earlier than expected.
