Question about 1998 Mercury Villager
It is very hard to turn to the left. I could change the power steering pump myself. But I am not sure if thats the problem,the fluid is at the proper level. Is there a way to test the ps pump?
GM had a recall on the rack and pinion steering for that vehicle. call the dealer for a free fix to the problem. Khatmandu

Most of the time the pump will make a whining noise when used. this is a warning for a bad malfunctioning pump. if there is no noise during a hard turn, it will most likely be an issue with the steering assembly. heres a step by step guide on checking the pump.
Step1 Check the fluid levels of your vehicle first. Add power steering fluid if necessary before you proceed any further. Step2 Connect the power steering pump and hose to the pressure gauge and shutoff valve. Fit the hose to the power steering pump correctly. Make sure the shutoff valve is open before test the power steering pump. Step3 Idle the engine while turning the steering wheel all the way to the right and all the way to the left to release any air from the power steering pump. Step4 Close the shutoff valve to check system pressure for about 5 seconds. If the shutoff valve is closed longer than 5 seconds, your power steering pump can overheat and this can cause damage to the pump itself. Step5 Compare the pressure reading against the manufacturer's specifications. If the pressure is within limits, your power steering pump is working correctly and you're ready to roll. Step6 Troubleshoot if the pressure reading is not the same as the manufacturers specifications. Consult the manual for your vehicle or for your power steering pump (if you just installed a new one) to determine the source of any further problems.
