I just got this van. When I test drove it last week, I guess I didn't
adequately test tight right hand and left turns or it has developed a
noise since. I never hear the noise going straight, but when I make a
moving right hand turn, it sounds like a suspension-type noise (low
pitch creak, NOT high pitched or groan) at about halfway thru the turn,
even when turning slow as into my driveway.
I did check the fluid and it was not bright red, brown-ish red so I
took it to get the fluid changed today. I had the mechanic do the power
flush, disconnecting return line, cranking, filling, etc. Used Mobil 1
Synthetic Mercon/MerconV, the multi-vehicle fluid. Fluid looks great
now, it was a perfect exchange.
Driving home I am noticing the same noise when turning left now. I am
guessing that having the van lifted up shifted things around a bit. It
really sounds like my struts or something in the steering assembly,
rather than the power steering pump, but I have to admit the only
failure I have had in the past on other vehicles resulted in obvious
pump groaning, but still, I just don't think it is the pump.
I don't get any noise if I am turning the wheel at a standstill under
power (neither was there any noise when it was on the lift turning left
and right) and neither do I get any when bouncing the car either over
bumps or at a standstill, only on slow turns.
