$3000 is way high. And if you were really losing fluid through the rack your level would drop. Quickly. And your steering would get hard.
I’ve seen this ploy used as a revenue generator. Before doing anything I suggest that you monitor your power steering fluid level for a while and see if you’re losing any.
I’ve also seen valve cover gaskets used as a revenue generating ploy. Is oil dripping onto the manifold? Do you have small puddles in the driveway?
Unless, of course, you’ve been seeing puddles in your driveway and have the other symptoms mentioned.
