power steering problem? or AWD binding?
i'm trying to sort whether my power steering pump is giving up, and whether to replace it, and it dawned on me that the noise/symptom i am experienceing could be an AWD binding.
at very slow speeds, like parking lot speed, at nearly full steering lock,
i get a savage deep groaning noise. there is no radical vibration associated with it, but you can "feel" the groan/grind in the steering wheel.
upon quick inspection, the drive belt for the power steering pump feels to be in decent condition, and tight enough.
the power steering fluid reservoir is full, possibly a bit over-full.
i am going to fasten a microphone under the hood in front, and then zip-tied directly to the PS pump, and then compare the recordings. if the groan is coming directly from the PS pump, the contrast in the recordings should be obvious.
aside from cleaning the screen in the PS fluid reservoir, and without dropping the cash and the labour to replace the pump,
... is there a better way to diagnose whether my PS pump is dying, or if there is some other cause of the noise and stiff steering?
this behaviour is fairly 'new', and samatha, my '92 previa, has about 215k miles on her
thanx in advance for any help or advice
