Rack and pinion gear wear is usually caused by long-term use and lack of proper lubrication. Especially in hydraulic power steering systems, rack and pinion gear wear will directly affect the pressure transmission of hydraulic oil, causing the steering wheel to turn heavy.

Typically, a repaired rack can last 3 to 5 years, or even longer, depending on the type of vehicle, the environment in which it is used, and the maintenance it has been given. If there are obvious problems such as steering stiffness, abnormal noise, or oil leakage after the repair, they should be inspected and replaced as necessary.

The production cost of a car is one of the key factors in determining whether to use a power steering rack. For some economical models with limited budgets, using a traditional mechanical steering system can greatly reduce manufacturing costs.
-
The power steering gear and rack and pinion are the two core components of the steering system. They are not directly "connected" to each other in terms of physical structure, but work together through control force and power assistance.

1970s: Power steering becomes standard in cars In the 1970s, power steering racks gradually changed from an optional configuration to a standard configuration for most cars on the US market. In particular, as the size and weight of cars increased further, manual steering systems became increasingly impractical.
-
The power steering gear is connected to the vehicle's steering link, which is directly connected to the wheel knuckle. When replacing the power steering gear, the steering link must be removed from the steering knuckle.
-
If the power steering pump is over-operated for a long time, especially when driving at low speed or parking, the pump will generate too much heat due to excessive load, which will directly accelerate the deterioration of the fluid.

Manual steering system: no steering fluid is required. Hydraulic power steering system: steering fluid is required. The steering fluid in the hydraulic system is responsible for transmitting pressure, lubrication and heat dissipation. Electronic power steering system: no steering fluid is required.

Can rack and pinion gear get clogged?
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.

Oil leakage is one of the most common problems in Ford Fiesta steering rack, especially in aging or damaged steering systems. Oil leakage usually occurs in hydraulic power steering systems. Although most modern Ford Fiestas use electric power steering (EPAS) systems, hydraulic systems are still used in some older models.
