Hi 2D i believe this is normal .....mine does it...but dont keep turning the wheel on full lock you are putting to much of a load on the pump etc

or it could just be a slightly loose belt or may need spraying....gave mine to lexus and they put belt spray on....and then fitted a new pump but still does the same?

:winky:

Pressure relief valve working causing resonance in the pipes

I have the same problem, ive put it down to a loose power steering belt.

Rob, what does that mean? Id like to look into it more, but no idea where to start.

Cheers

pipes do seem 2 move a tad

but u carnt see when movein car so only seen this when its parked

ok u have a steering pump that pumps fluid to 1 side or the other of the steering rack depending on the position of the steering wheel, if you go to full lock you are putting fluid all on one side so valve is fully open - somewhere is a pressure relief valve, if the valve is fully open presure is only on the 1 side and that pressure builds up so u need someway to relieve it. whether it be by pump design or a primative pressure releif valve - as the pressure is released u can get a resonance ( or a chattering) of the valve this can sound like a squeal.

turn the steering wheel slowly to full lock, when the sounds starts stop turning the wheel and then rev the engine a fair bit what happens then???

mine has never made a sound so i cant check this - would be interesting

Is it something that has suddenly started or it has always done it? Is the power steering fluid topped up to the correct level?

No idea either on the IS, I'm sure someone will check it out for you on Sunday if all else fails.

look in the owners manual under servicing it shows u everything there...

and of course if it has only just started to do it after a service then i woud get it checked out, there are quitea few people on here that have had exactly the same sounds

[Rikos]

The power steering is the one that stands on it's own under the bonnet and comes out from the back of the bonnet on the left hand side. Although i could be wrong.

[Lexus2D]

Yeah iv seen the steerin & u r correct Rikos :)

No it did it b4 2 thought it would have sorted it

Backed it out this morn when it did it i reved it like u said & it squeeled even more
