My Buick LaCrosse started a whining noise that gets louder when you increase speed. When the car is in neutral the noise is the same when you increase the RPMs and the noise gets louder. Periodically when making a left or right turn a loud sound will come from the passenger engine side. Also, if the car is in neatural and holding the Rpms around 2000 when I turn the wheel at the same time the whine noise gets louder.
I have made sure the power steering resivor stays full and the noise has been around for 2 months now. Tonight I jacked the car up and found a small fluid oil stain on the driver side rack and pinion rubber boot the covers the tie rod. The passenger side rack and pinion boot was dry and clean. Also, I looked around the power steering pump and did not see any leaks.
So I am trying to figure out if the power steering pump is going bad or the rack and pinion is on it's way out. My thoughts are it is the power steering pump cause it has that whine noise constantly when the RPM's increase and gets louder if you turn the wheel left or right. Or both are on their way out, just looking for some input.
