Power Steering Pump problems of the 1996 Mitsubishi Galant

I purchased this vehicle Jan 2000 and during test drive I heard a noise in the power steering. I reported it to the salesman at phil hughes Honda. He had his used car mechanic take a look. The mechanic was to have lubricated it. Second trip following week and mechanic lubed again and I was told to sometime drop by their Mitsubishi dealership down the road and have them look at it. I immediately went there and they had to tighten loose belts that twice before went unnoticed by their associate dealership used car mechanic at phil hughes Honda. The Mitsubishi dealership service manager was very helpful and assisted me by finding the problem and correcting it. There is an occasional slight sound that is mild that I will have checked out.
