How to tell if the power steering pump is broken

The power steering pump is a very important part of the car. When the power steering pump fails, the driver will feel that the steering wheel becomes very heavy, and even cannot control the vehicle normally. So, how to judge the power steering pump is broken?

1. You can judge whether there is a problem with the booster pump by listening to the sound. When starting the engine, idling, or driving, if you hear strange noises or other sounds, the sound of the booster pump is very obvious when you turn the steering wheel or increase the accelerator. At this time, it is necessary to listen more carefully to identify whether these sounds come from the power steering pump.

2. Check the booster pump for oil leakage. When the oil pipe and oil seal are aging or the screws are loose, the booster pump is prone to oil leakage. For this reason, the sealing ring needs to be replaced in time to keep it in good condition.

3. You can judge whether there is a problem with the power steering pump by driving the vehicle. When driving slowly at a speed of no more than 20km/h, observe whether the steering wheel becomes lighter. If the steering wheel becomes heavy or feels stuttering, the power steering pump needs to be replaced.

In addition to the above methods, you can also use a variety of performances to judge whether the power steering pump is faulty. For example, after stepping on the brake pedal, you will feel that the brake is obviously hard, the pedal is not assisted, and even does not return to the position. The failure of the power steering pump will have a great impact on the driving process, so it is very important to check and repair in time when there is a problem.
