Steering becomes difficult If the electric power steering rack is damaged, one of the most obvious manifestations is that the steering wheel becomes difficult to turn. This is because the motor cannot provide normal power assistance, and the driver needs to rely on more force to complete the steering operation.

The steering wheel makes abnormal noises when turning, especially "squeaking" or "banging" knocking sounds, which are often early signs of wear or damage to the power steering rack end. When the seals or lubricants at the rack end are lost, friction increases, causing wear between parts, which in turn causes abnormal noises.

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.

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.

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.

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.

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.
