Does a Mondeo make an odd noise on turning?

[Acheron]

It's done it much more so when cold, and when turning the wheel at slow speeds or at standstill. It kind of sounds like a metallic screech noise. Not too loud but easily noticeable.

Thought it might be the PAS pump, but someone i spoke to said it was normal.

Any ideas?

2004 ST220 if it matters.

Grit between the disc and back shield? (does it have a shield? Can't remember)

Check your power steering fluid level.

Mine has started doing the same in the last few cold days.

Only the 98-plate station shed so not too fussed but would be good to know what it is. Will check the PS fluid tomorrow.

I'll check the PS level this weekend too.

To best describe the noise, i found this on youtube;

Ok so its a diff make model and type etc but its the same noise but a higher pitch, and i dont notice it when the car is doing more than 6 or 7 mph.

Drive belt slip, or some catastrophic failure of the pump. More likely the former. Could also be wheel bearing or spline wear which is cancelled out when warm, but unlikely.

Do the maintenance bit first and check the fluid level and have the drive belt checked/changed.

That Type R video sounds like a knackered wheel bearing causing disc to hub interference or diff bearing shaft to case interference. Most modern FWDs have an interim bearing between the diff and the front driver's wheeel to counteract torque steer, it can perish too and give off shaft to casing sounds. Result of too many fast right-lock getaways usually...

Your power steering fluid is dirty. Mine sort of squeals and whistles when cold, it's just a normal hydraulic noise. It's been doing it for a year, and it's been fine.

S-Max at work does that and it's brand new.

Checked the PAS fluid and seems AIO. I've recorded the sound of it on my phone, although its a crap phone so crap quality.

i'll get round to hosting it tonight.
