Hi, I have a 99 Oldsmobile aurora. 166,000 miles.I'm trying to fix all the problems for the wife before I deploy in June.I got a buddy helping me with the brakes but here's my two issues.
#1. There's is a kind of a screeching or squeaking sound only when I make a left turn. Not always though, if I turn slightly or really turn it's there but I can find the spot with no noise and can turn depending where I move the wheel.
#2. The car whines a lot, when driving, or not.I can turn the wheel and it stops for a moment but whether I excel or just sit there it whines.
. All fluids are good. Besides the brakes I'm also doing serpentine belt.A few suggestions for the noise were;The ac compressor or the power steering pump. Someone even said maybe a trans flush, but it shifts with no problems. Any help is appreciated.I would donate If I can find the answer.

Do you
have the same problem?

Appreciate the quick response. So it looks like psr steering pump is the problem. Do you think all those noises(prob.#1)stem from that?

Very likely belt could be slipping while tuening. Possible weak belt tensioner
