why does it leak in the back of the car when the Power Steering fluid is put in the front of the car??
Yes, a power steering pump can leak because of overfill or cold weather. As the seals are damaged due to pressure from overfill or due to freezing, the pump can leak.
Clean the power steering are real good check for where the leak is coming from and go from there. For example if a hose is leaking replace hose, if power steering pump seals are leaking replace pump, exc.
If your power steering pump makes a whining noise as you turn your steering wheel your power steering fluid reservoir is probably empty. The noise is caused when your power steering pump tries to pump fluid that is not there. This indicates that you probably have a leak somewhere in your power steering fluid lines. You can either try to find the leak or simply replace the power steering fluid every so often.
A loose power steering belt or the power steering pump has failed or the power steering fluid reservoir is empty because of a leak in the system.
You have a leak. The leak can be from the pump or any of the fittings. You may also have a leak at the rack & pinion.

To fix a power steering leak on a Mitsubishi 3000GT, first identify the source of the leak by inspecting hoses, connections, and the power steering pump. Once located, you can either tighten loose connections, replace damaged hoses, or, if the pump is leaking, consider replacing it. After repairs, refill the power steering fluid and bleed the system to remove any air. Always ensure to use the correct type of power steering fluid recommended for your vehicle.
