1. Water penetration into the steering gear
When a car runs through a puddle, water may enter the steel gear, causing abnormal noise and electric circuit failure.

2. Abnormal wear of gear and rack
If the bearing capacity of the gear is low and the rack is in a floating state, the angle between the gear and the rack may change under impact, leading to poor engagement.

3. Steering gear design defect
Damage due to poor engagement or abnormal contact between the gear and the rack may result in failure of the steering gear.
