How to solve the abnormal sound of Ford Roadwalker's front axle

1. The weather is cold in winter, and the rubber part of the suspension system is harder than that in summer, so the abnormal sound will be more obvious in winter.

2. Check whether the rubber parts of the suspension system are abnormal due to aging and cracking, and check whether the plane bearing above the lower shock absorber is worn.

3. Check whether the shock absorber of the lower suspension system leaks oil and whether the ball head is loose.
