What Causes the Clicking Sound When There's Play in the Half Shaft on Slightly Bumpy Roads?

[Asher]

There are generally two reasons for abnormal noises from a vehicle's half shaft: 1. Loose half shaft bolts causing play at the connection point, resulting in noise (this can usually be seen directly). 2. Broken teeth on the differential planetary gears—this type of noise typically becomes more noticeable when turning left or right or during normal driving. Additional relevant information is as follows: 1. If the vehicle's half shaft is damaged: It can cause abnormal vibrations while driving, as well as unusual noises. If the half shaft is damaged, it should be replaced immediately. When replacing the half shaft, it is recommended to choose original equipment manufacturer (OEM) parts and have them installed by a professional shop. 2. The half shaft is the component that transmits power to the wheels: Without a half shaft, power cannot be delivered to the wheels. The half shaft may become deformed or even break.
