Although hydraulic power steering racks were once the mainstream choice for automotive steering systems, with the advancement of electronic technology, other types of steering systems have gradually occupied an important position in the market. However, this does not mean that hydraulic power steering racks have been completely eliminated.

Improved energy efficiency A significant advantage of the electric power steering rack is its higher energy efficiency. Unlike hydraulic systems, the electric power steering system only activates the electric motor to provide assistance when steering assistance is needed.

The launch of the power steering system is an important part of its innovation history. General Motors officially launched the power steering system in 1951, and it was first used in some models of the Cadillac brand.

The power steering rack is usually equipped with seals at both ends to prevent fluid leakage. However, as the vehicle is used for a longer time, the seals will lose their sealing ability due to wear, thermal expansion and contraction, or material aging. Once the seals are damaged, the fluid will leak out from both sides of the steering rack.

If you often drive on the highway and need stable directional control and less fuel consumption, the electric power steering rack is still the first choice. It can provide consistent power assistance to ensure stability when driving at high speeds.

In general, it is recommended that car owners replace the steering fluid every 2-3 years or every 50,000 kilometers. Of course, the specific replacement cycle should also refer to the recommendations of the vehicle manufacturer.

Leaks in hydraulic systems are usually caused by aging, wear or improper installation of mechanical parts. Power steering rack leakage is mainly concentrated in key components such as hoses, seals, joints and hydraulic pumps.

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.

When the power steering system fails, the driver needs to rely on more manual force to turn the steering wheel, especially when driving at low speeds or parking. Without power assistance, the steering wheel becomes extremely heavy to turn, which is a big challenge for some drivers with less power.

When the hydraulic power steering rack becomes loose, the response of the steering wheel may become sluggish. When the driver turns the steering wheel, he does not feel the immediate response that should have been there, but needs to spend more force or time to complete the steering operation.
