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.

Some reports indicate that in the case of severe leaks, if the owner checks the fluid level before starting the vehicle and replenishes the fluid in time, the vehicle can be driven for about 400 miles. However, this practice is only a temporary measure and is not a long-term solution.

Once a leak occurs, the hydraulic pressure of the system will drop, resulting in weakened power assistance or complete failure. In this case, the driver needs to use more force to turn the steering wheel, especially parking and turning operations at low speeds will become very difficult.

If the gears inside the steering rack are worn or loose, it may make an abnormal knocking sound when the steering wheel is turned. In addition, insufficient lubrication of the steering gear may also cause this situation.

If the motor in the electric steering rack fails, it is generally repairable. Common problems with motors, such as brush wear, coil breakage, or poor electrical contact, can usually be repaired by replacing certain parts of the motor.

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.

The weight of the power steering rack varies depending on the model and design. Generally, its weight ranges from 10 kg to 30 kg. The hydraulic power steering rack is usually heavier than the electric power steering rack. This is because the hydraulic power steering system needs to include components such as hydraulic pumps, fuel tanks, pipes and control valves.

The Buick brand truly applied the power steering system to mass-produced models on the Buick Roadmaster launched in 1952. As the flagship model of the Buick brand at the time, Roadmaster represented Buick's highest level in the field of luxury cars.

The main components of power steering fluid are mineral oil or synthetic oil, which become more flammable in high temperature environments. When power steering fluid leaks into the engine compartment or the bottom of the vehicle, especially near hot parts such as the exhaust pipe, engine, spark plugs, etc., there is indeed a potential risk of causing a fire.
