Vibration On Steering Wheel

[Guest Davej]

Hi to you all newbie to the furum and to the Galaxy.

 

I have a small vibration on the steering wheel that comes and goes, no patern to it and it happens when i am in motion as well as being stationary. When i am stationary and i turn the wheel the revs raise by a few revs is this normal on a 97 2ltr or do i have a problem any help would be appreciated,

 

Thanks in advance

The revs raising is because as you turn the wheel, it puts a load on the PAS pump which causes the engine to slow, the ECU picks this up and increases the idle speed. Not sure on the vibes though..

Thanks Mike for your info, I think the vibration is coming from the power steering pump but not sure, feels like a vibration you would get from a tropical fish tank pump .

Make sure all the pipes for the PAS are correctly fixed to their mounting points, and not touching any bodywork as this will transmit the vibrations (although they are more than likely just the pulsing of the fluid) As a try at narrowing it down, get someone to hold it on lock as you are under the bonnet and feel the pipes and pump for vibration.

I get this effect on my Ally.Its perfectly normal.As GSM says,its the PAS pump compensating for the load put on it by you turning the wheel...........
