The work of the steering rack and pinion involves a lot of friction and mechanical stress. If these metal parts are not adequately lubricated after long-term use or dry-grip due to lack of power steering fluid, they will gradually wear or produce gaps. These wears will destroy the sealing of the rack system and allow hydraulic oil to leak from these gaps.

If your vehicle is equipped with a hydraulic power steering system, first check the level of the steering hydraulic fluid. If the level is too low, there may be an oil leak, which is usually one of the signs of a damaged steering rack gear.

Natural wear and aging are one of the most common reasons for replacing a power steering rack and pinion set. The rack and pinion will constantly rub against each other during long-term use, and although they are usually made of high-strength materials, they will inevitably wear out.
