Power Steering Pump problems of the 1999 Chevrolet Suburban

I purchased the used vehicle from glendale car connection at on 8/28/03. I noticed on the day of purchase it seemed hard to steer the vehicle so I mentioned it to the sales person as well as the office manager. It was scheduled to be repaired. I drove the vechicle home that night I begin to notice a hard turn made the vehicle make a noise I too the vehicle back to glendale car connection were the mechanic told me the power steering pump was going out and he change it I also asked about the brakes squealing and he said the vehicle needed brake fluid which he put in. I took the vehicle home and begin to drive it I noticed it was getting hard to turn and it would swerve while driving it, I contacted the dealer again. The office manager kathy baggett told me it was not covered under my warranty and the company would not fix it so I had to pay to get it fix, at this time the brakes still squeal and I have used tires on the vehicle that are different sizes. Katy stated at the time of purchase for $100 more she would supply the vehicle with new tires. I feel I was sold an unsafe vehicle and when I brought it to their attention the company did not care.

Ea99011, erratic power steering assist while driving. When taking off from a stop or making at right or left turn, there is vibration and a moaning sound coming from the steering. Dealer has been told about the problem more than once. Power steering pump has been replaced twice, but the problem continues. Please provide any further information.

During a left hand turn, at approx. 45 mph, the steering wheel becomes loose, then stiff and is very difficult to control. The fluid level of the power steering pump is a t it's proper level and the belts have been replaced. I have had it at (2) separate shops and neither have reported any problems with the front end at all. ***dimsii ivoq entry posted after 12/12/02 cut-over to artemis****770103.
