Power steering judder

[Blackpool350ZCS]

Hi

my 350z has a steering judder, mainly when it’s slow or on the spot. It also goes through power steering fluid. No visible leaks. Does anyone have any idea? Is this a common fault?

 

thanks

If you are using pas fluid then there must  be a leak and low fluid or air in the system will give you a judder

Thanks, the leak is the hard bit to find, doesn’t want to present itself anywhere

Well, news on this. Tried removing the fluid and a can of stop leak back in, top up, remove air and so far so good. May have just been poor quality fluid
