My friends have a 1.6 Zafira on an '04 plate.
They asked me to have a look at it for them, as the steering was really heavy all the time. I had a look around, and couldn't see anything obvious, so told them to top up the power steering fluid just incase, as it was making a weird slushing sound inside the cabin when adjusting the steering.
This fixed it, and brought the power steering back. 2 days later, the problem had recurred.
Anyone know of any common places where they can leak power steering fluid?
