W124 power steering noise at full lock?

[ShivaYash]

Hello

I've searched the web for more information on this but cannot find anything.

My steering makes a noise, a sort of hum, at full lock, and the revs increase, ever so slightly.

Is this normal? The front wishbones and bearings are new, I replaced them as they had seized.

I realise changing the fluid is a pain but some advice on what colour it should be would be great. I have some Castrol ATF and will top up tomorrow should it be needed.

On full lock a relief valve has to open and quitre normaL

Many thanks - I am just being too fussy I guess, it makes a slight noise at the midpoint too. I'll have it properly checked out at the next service.

Perhaps change the aux belt if worn. Usually around £8 for an OEM part so not too bad.

Will do - many thanks.

Mine starting to 'whine' quite badly when turning wheel. Happened about a year ago and steering got very heavy but I topped it up and it was grand.

Thought I'd just do the same this time but fluid level is ok

That is annoying. Mine makes a slight noise at the mid point. Shall get it checked out.
