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.

The power steering pump is an important component in the power steering system of a car. Its main function is to provide power assistance through the hydraulic system, allowing the driver to turn the steering wheel more easily. In other words, the power steering pump is responsible for converting the mechanical energy of the engine into hydraulic energy, thereby reducing the force required for steering.

When the power steering pump fails, the driver usually feels that the steering wheel becomes heavier, but there is no obvious jamming feeling. When the power steering rack fails, the driver may feel a change in the resistance to steering wheel turning, especially jamming at certain angles.

For leaks at the hose or accessories, replacing the damaged hose or accessories is the best way to stop the leak. Aging or damage to the hose is one of the main causes of power steering pump leakage, so it is very important to check the condition of the hose regularly and replace it in time.

Under normal circumstances, the design life of the power steering pump is 150,000 to 200,000 kilometers. When the vehicle mileage reaches this range, even if the power steering pump has not yet shown obvious failures, the owner should consider checking it and replacing it if necessary.

If the power steering pump fails or its performance deteriorates, the pressure of the hydraulic oil cannot be effectively transmitted to the rack and pinion, and the driver will feel that the steering wheel becomes abnormally heavy, especially at low speed or parking.

As a luxury car, the replacement cost of the power steering pump of Buick LaCrosse is relatively high. The total cost is usually between $300 and $800.

A power steering pump is a device specifically used to provide hydraulic power to a vehicle's power steering system. Its main function is to convert the engine's mechanical energy into hydraulic energy, and through the flow and pressure of hydraulic oil, the auxiliary steering system reduces the force required by the driver to turn the steering wheel.

The power steering pump (Power Steering Pump) is one of the key components in the power steering system. Its main function is to generate hydraulic oil flow through mechanical force to provide power to the steering system.

Due to the different viscosities and compositions of the transmission fluid, it may not provide the ideal lubrication required by the power steering system. This will cause increased friction inside the pump and pipes, and long-term use may accelerate wear and shorten the life of the pump.
