I've been advised that the Power Steering pipe of my ZR needs to be secured properly to its mount front underside. Told it will be a very minor job, but its very important it gets done. How much would you expect it to cost anyone?
I would put it on top of your to do list really. If the power steering pipe rubs through or splits ps fluid could contaminate the belts, also the obvious lack of power steering will result. If this happens while your going round a corner you could be in for a surprise!
Although it is only a minor job, better safe than sorry!
