20 models of four-wheel drive A6L–abnormal sound replacement bearing

September 7, 2024

There is abnormal sound in the front wheel because the sound is small, but now it is obvious (the buzzing sound of the front wheel). After a brief communication with the 4s shop after busy afternoon, it is found that the damage to the left front wheel bearing caused abnormal sound. During the warranty period, the manufacturer can claim for replacement. It was already 5:30 when it arrived, and it took two hours to replace it. In order not to delay the car, the masters decided to work overtime to complete the task (it was really enough to work hard). The bearing is to bear the load and provide precise guidance for the rotation of the hub. It bears both axial and radial loads. Bearings must be installed in a clean and tidy environment, and fine particles entering the bearings will also shorten the service life of the bearings. It is not allowed to hit the bearing with a hammer, and be careful not to drop the bearing on the ground (or similar improper handling). The condition of the bearings and bearing housings should also be checked before installation. Even slight wear can lead to poor fit and cause premature failure of the bearings. Therefore, bearing damage must be replaced as soon as possible. Damaged steel balls or support frames will increase more serious wear in the bearings, increase abnormal noises during driving, tire wear, reduce controllability, increase the bearing clearance and lose balance, lead to steering wheel floating failure and cause traffic accidents endanger lives.
