Shock Absorbers Troubleshooting

Shock absorbers is the vulnerable parts in the process of car use, shock absorbers work good or bad, will directly affect the service life of the car moving stationarity and other parts, so we should make the shock often is in good working condition.Can use the following method to test of shock absorber work are in good condition.
1. The cars are driven on poor road conditions of the road parking after 10 kilometers, with the hand to touch the shock shell, if not hot enough, suggests that the shock internal resistance, shock absorber does not work.At this point, add the appropriate lubricating oil, and then to test, if the shell heat, lack of oil for the inside of a shock, should add sufficient oil;Otherwise, the shock absorber.
2 . Press firmly on the bumper , and then release , if the car has a 2-3 jump, then the shock absorbers work well .
3 . When the car slowly driving and emergency braking if the car more violent vibration , indicating a problem with the suspension .
4 . Remove the shock absorber to be upright , and the lower end of the connecting ring in the vise clamp , pull the lever several times to press the shock , then there should be a stable resistance , pull up , the recovery should be greater than the resistance of the downward pressure when resistance , such as resistance to unstable or no resistance , may be short of oil inside the shock absorber valve parts or damaged parts should be repaired or replaced .
In determining the shock absorbers have a problem or failure , it should first check the shock absorbers for oil leaks or traces of old oil spills . If it is found leaking , first tighten the cylinder head nuts, if the suspension is still leaking , there may be oil seals, seal washers failure , should be replaced with new seals. If you still can not eliminate oil spills, should pull rod suspension , if they feel there is no issuer or the severity of the moment , and further check clearance between the piston and cylinder is too large, whether the shock absorber piston rod bent piston rod cylinder surface and if there is scratched or pull marks.
If there is no oil leakage phenomenon shock absorbers , shock absorbers should check the connection pin , connecting rod , connecting hole , rubber bushings and other damage, sealing off , break or fall off place. If the examination is normal, should be further decomposed shock absorbers, check with the gap between the piston and cylinder is too large cylinder with or without strain, the valve seal is good, valves and valve seat are tight fitting and avoid Zhen 's done spring is too soft or broken , take grinding way to repair or replacement under the circumstances .
In addition, the suspension will appear in the actual use beep failure , which is mainly due to the suspension with leaf springs , frame or shaft collision damage or loss, and cushion the shock absorber tube deformation dust , oil lack of other causes , reasons should be identified , to be repaired.
