Roscoe Posted November 10, 2013 Share Posted November 10, 2013 Evening all, any help on this will be appreciated. Recently my 08 zed has developed a judder/pulsing through the steering wheel at any speed. The judder can be felt through the steering wheel when stationary, going into roundabouts and coming out as you bring the steering back to straight. So basically any input you can feel the judder. Fluid is at the correct level, no bubbles visible in the res when going lock to lock, no leaks can be seen. Tyre pressures are all spot on, I have noticed that the front tyres inside edges are getting slightly low but surely this would not show itself as judder when stationary. Full alignment carried out a few months ago. Thanks in advance Quote Link to comment Share on other sites More sharing options...

Roscoe Posted November 10, 2013 Author Share Posted November 10, 2013 does it do it when you turn the wheel when stationary? Yes most of the time. It's more Noticeable when driving into or around a corner. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Roscoe Posted November 10, 2013 Author Share Posted November 10, 2013 power steering pump? Would the pump failing not show signs of the steering becoming heavier and make noises? No unusual noises are apparent. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
gareth29 Posted November 10, 2013 Share Posted November 10, 2013 I had a similar problem on my vw and it turned out to be the clutch pulley on the alternator, which had seized. Theres plenty on youtube about them. I changed the pulley and it was instantly cured. Not 100% sure the z has one but most modern cars do apparently.

Roscoe Posted November 11, 2013 Author Share Posted November 11, 2013 All belts and pulleys checked the belts look good, no slipping. Not making any strange noises from the pump either. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
R35LEE Posted November 11, 2013 Share Posted November 11, 2013 Power Steering pressure switches go mate. I have 3 of them. Can you get an engineer to look at it or specialist garage? Where are you based? Quote Link to comment Share on other sites More sharing options...
WhackyWill Posted November 11, 2013 Share Posted November 11, 2013 Would it be a tyre problem.. Quote Link to comment Share on other sites More sharing options...

Where are you based? Hi mate I am an engineer just havnt got ramp access to get underneath and have a look. Gone as far as I can on a wet Stoney driveway. I'm based in ampthill, near Bedford. I'm not sure where my closest zed specialists are, probably cougar. Are these common to fail then on the zed's?

R35LEE Posted November 11, 2013 Share Posted November 11, 2013 PS Pressure switch is common mate ye but if it doesn't fix the issue its a pump that I also have. Keep me updated and PM sent Quote Link to comment Share on other sites More sharing options...
