Shock absorbers under weight of the car, will it last deadlines, such as aging, fuel oil, different sound, deformation... So how to know what kind of situation need to change? Moving in general by shock absorbers, there will be shaking, bounce, noise more phenomenon, at most carsick, take uncomfortable, if there are shaking, bounce, noise and such, you'll have to deal with the suspension.

How to check? First of all by hand to try to pressure car four horns, and then let go. Normal shock absorbers a YaChe behind him, the car immediately stop shaking up and down, loosen up most after a set live feeling more hard, but the suspension will have problems at two or three times before he stopped and the soft, because the stock damping have lost, with only a circle of spring bounce, such body easy shake it is easier to carsick.

If front wheel has a strange sound shock absorbers, you can open the hood, and the center of the box-office shock dust cover up (some car didn't cover, some are off) there will be butter, also can see the shock absorbers center fixed nuts, use your fingers touched gently fixed nuts, another hand pressure body let body movement up and down, if feel center nuts have buckle buckle buckle striking the feeling, that shock absorbers is (you can also find someone to help you pressure body, tend to have feeling) normally won't feel, only the front wheel (rear wheel to open the back seat more troublesome, unless you will open)

Another relatively direct method is to see whether there is shock oil leakage (outward appearance ShiShi is oily, normal is powder dry powder dry), some shock absorbers didn't leak oil leak only becomes invalid. If want to change about best together in shock, both sides will balance, or new old can cause new shock force is too large, shorten life, and can separate change, not necessarily to be round, unless really all not line, some maintenance factory will really eye ShuiXiaHua, people will all change, so want to be first ego check to insurance.

Sometimes dismantling the shock to check after shock should be seated, have crack, cushioning, rubber deformation, center bearing loose... If you still don't change, some get new gate is the original factory, very hard not original soft, mount may comfort can be reduced, bounce are obvious.

The next step is the quality of the shock itself, some manufacturers to reduce cost, use lower quality materials, before long will oil leakage failure, and even too soft too hard, so too cheap or not famous brand shock absorbers also don't take chances; The technician experience and assembly of how, some small details haven't noticed word, also can have loaded askew, with bad may, before long will also have different sound out, then spend money has not processed and to open a.

Chassis vision of the sound nine times out of ten are from shock absorbers, but the other part is going to be a problem, but by professionals will put the car up the check, the money to spend on veins on, this change to change, or the original normal for quality of the club is bad outside, by paying to sin, may not change also is better
