My 75 vette has had a quite leaky power steering system since I got it. From looking at the ps control unit, it looks like a previous owner unsuccessfully attempted to 'rebuild' it. I've purchased a rebuilt control unit, have replacement hoses, and have a gasket kit for the cylinder. I also got instructions for how to replace/rebuild the ps from http://www.zip-corvette.com/psr.htm although one of the steps is to 'bleed the ps system.' Does anyone know how to do this? And any other advice on performing such surgery on a 70s corvette power steering system would be appreciated..... I want to eliminate my leaks, but having a properly functioning power steering system AFTER I'm done is important, too. Right now it works fine, I just have to add ps fluid about every other week....!!!!
