Nissan Urban Servodireccion very hard

Hello, I am Julio and greetings to all on this site and for being my first post. I like to repair my damage and I just got an urban panel of 2004 and I don't know if you use a pulley hydraulic pump or it is internal in the engine. The address is super hard, I still don't inspect it and I would like some contribution. It will help me. thank you

If you have a hydraulic bomb they never go with distribution always break on the outside, but if it does not bring it can have electrical direction that does the same but it is other history.

Thank you but inspect personally and observe that you use gear pump in the engine without pulley, also note when you re -apply the pressure that you have even if you do not need. With the system without fluid the direction softens the opposite when full of fluid. It seems strange because it should be the opposite. Now when I try to purge the system of the system (I turn the direction in one direction) the fluid returns to the deposit and does the opposite when it turns to the opposite direction. I am in doubt that it is the damaged pump and I do not know if it can be the distributor valve or there is communication between the cylinder embolos, the truth is that I am ignorant and I hope to help some with some more detailed manual of the failures. Thank you.
