Whining / whistling noise when turning the wheel (PAS?)

[edd1e]

Hi guys, I bought a 172 on the weekend.

I get a whining / whistling noise when i'm turning the steering wheel, both when moving around town and stood still. If the wheel is dead still it doesn't not make any noise.

Obviously I guess this is PAS related issue, is it likely to be the PAS pump or AUX belt tensioner... or something else?

The service book does not state that the AUX belt has been replaced, but the cam belt deffo has been changed.

Any ideas?

OK, its not the PAS I don't think.

When the ignition is off I still hear the high pitched squeak when I move the steering wheel side to side a little bit. The noise sounds like it's coming from down by the wheels. A bush/joint maybe?

When investigating this problem i noticed my top mounts rotate as the steering wheel is turned....?! I've never noticed this before on any of my cars. So this may be a stupid question but are they supposed to do this? Not sure if these problems are linked?

Go to 0:18 for what i'm talking about (you can't hear the high pitched squeak I mentioned this video BTW)



Are my top mounts screwed?

have you tried bleeding the power steering fluid? might do the trick.

I think it's bush / joint / mount related now tbh as it does it with the ignition off (should of checked that to start with!)

I'm getting this too, car was fine 2 days ago all but the alignment being slightly off.
Had to lift mum tonight as some w*nker danced on her windscreen and it makes an awful noise when turning either way like a whine/groan.
Got out and check PAS fluid bottle - its empty! :S
