In our daily routine maintenance of semi-trailers, in addition to some components that require regular replacement, there are also some components that require regular inspection, such as the trailer's brake discs, brake pads, trailer brake pipes, steering rod ball joints, shock absorbers, and other rubber components, such as trailer tires, ball cage dust covers, upper and lower support arm rubber covers, and balance bar rubber covers, The failure of these components due to wear or aging can pose a safety hazard to the vehicle's operation, so we need to conduct very careful inspections of the chassis components while performing maintenance. The above discussion should be noted!

It should be noted that when most components of the chassis are damaged, it can cause abnormal or bumpy noises during driving. It is recommended that our driver friends, if they hear these noises, should quickly identify the location and cause of the problem, and then repair it according to the situation, in order to ensure driving safety as much as possible.
