Hydraulic power steering racks can significantly improve the controllability of trucks and reduce the labor intensity of drivers. For large trucks that are driven for a long time, hydraulic power steering racks make it easier to operate the steering wheel and avoid fatigue caused by long-term steering burdens.

From May 13 to 15, 2025, Lagos, West Africa - Foshan Diamond Auto Parts Co., Ltd. (DKM) will participate in the highly anticipated West Africa Automotive Show (WAAS) and sincerely invites new and old customers to visit the booth to discuss cooperation. This grand event will be held at the Landmark Centre in Lagos, Nigeria.

The operation between the rack and the pinion depends on adequate lubrication. When the power steering fluid is exhausted, this lubrication function fails, resulting in excessive friction between metal parts and abnormal wear. The gear portion of the rack will be damaged due to direct contact, and eventually the steering rack will fail.

Mineral oil hydraulic oil is the most common type of hydraulic oil, which is mainly processed from oil-based oil products extracted from crude oil. They usually contain additives to enhance the anti-oxidation, anti-corrosion, anti-foaming and other properties of hydraulic oil.

if it is only a small leak, the vehicle can still be driven for a short distance, but it needs to be checked and the hydraulic oil added frequently. However, if the oil leak is serious and the hydraulic oil is lost quickly, the vehicle may lose the power-assist function in a short time, and continuing to drive at this time will bring great risks.

The cost of replacing the steering rack varies depending on the model. For Mercedes-Benz models, the cost of replacing the steering rack is generally between $1,000 and $2,500. This cost includes the cost of parts and labor.

When the fluid is insufficient, the system cannot generate enough pressure, causing the steering wheel to become heavy or lose power. Insufficient hydraulic pressure usually causes the driver to use more force when steering, which is particularly noticeable when driving at low speeds or parking.

The work of the electric power steering system begins with the steering force sensor (Torque Sensor). When the driver turns the steering wheel, the sensor monitors the rotational torque on the steering wheel in real time. This information is transmitted to the vehicle's electronic control unit (ECU), and the ECU determines how much steering assistance is needed based on this information.
