How to check chassis parts

The chassis components that are most prone to problems, Jiahangaero said that knowing the early signs of failure can be well avoided Initiate a more serious situation.

From the point of view of use, chassis components are actually more prone to problems than engines, but during routine maintenance, many people often ignore the inspection of chassis components. The parts of the chassis that are prone to failure are mainly concentrated in:

• SHOCK ABSORBER: Oil leakage is a harbinger of damage to the shock absorber. In addition, the obvious aggravation of driving bumps on bad roads or longer braking distances are also signs of damage to the shock absorber.

• SUSPENSION CONTROL ARM BUSHING: After the bushing is damaged, the vehicle will have a series of failures such as deviation and swing, even if the four-wheel alignment is of no avail. Rubber boot damage is easy to spot if you inspect the chassis carefully.

• STEERING ROD: Loose steering rod is a serious safety hazard. Therefore, it is necessary to check this part carefully during routine maintenance. The method is very simple: hold the tie rod and shake it vigorously. If there is no shaking, everything is normal. Otherwise, the ball head or the tie rod assembly should be replaced.

• EXHAUST PIPE: The exhaust pipe is one of the most vulnerable parts under the car, so don't forget to take a look when it is overhauled, especially the exhaust pipe with three-way catalytic converter should be carefully checked.

• UNIVERSAL JOINT DUST COVER: Don't underestimate the dust cover outside the universal joint. It not only has a dustproof effect, but also prevents the loss of grease around the universal joint. Once the dust cover is damaged, the grease will quickly It will drain, and the gimbal is easily damaged due to dry grinding.
