Hello, I have a problem with the steering system of my V70 2.4 l (170 hp), Built 12/99. It all started with an ever louder servo pump, which finally leaked. The noise, a working noise of the servo pump, which can be heard even when the steering is full, became louder with increasing driving time until it was always heard. Then followed the change of the servo pump (replacement pump), the rib belt and the corresponding clamping/reversing roller. rdings is the problem again. After a short drive, the system and the engine are warm, you can hear this working noise of the pump with every steering movement, whether in the stand or during the ride. Enough servo oil is also in the system, I have checked several times. What can this be? What can this be? Is the steering gear over? Can you test it somehow? I still noticed the following: After the ride, the servo oil foams up strongly and there is a lot of pressure on the supply container. Servo system installs a filter that may have been added? If so, where does this one sit? Have you ever narrowed or clogged the pipes or hoses? Do you feel the pump has to work too hard. The pulley of the replacement servo pump has game, you can move them back and forth sideways. Is this normal? Actually, the disc should be stored and not allow such movements, right? Thank you for your help.
