The environment around the rack and pinion gear is relatively complex, especially in some harsh driving conditions, mud, sand, dust and other external debris can easily enter the steering system. These debris may accumulate between the rack and pinion gear, causing it to engage poorly.

Determine the design goals of rack and pinion gear according to the vehicle type, purpose and performance requirements. For example: How much steering force is required? What is the maximum steering angle of the wheel? What is the expected service life and maintenance cycle?

If the steering wheel is obviously heavy when turning, or the steering is not smooth, it may be that the wear of the rack and pinion gear has increased friction. In this case, the owner should check and replace the rack and pinion gear assembly as soon as possible to avoid affecting driving safety.
