how much sould repair of a rack and pinion cost on 1998 Buick Park Avenue

I had the pressure hose replaced and the pwr. steering stilled leaked. went to a shop and it was told to me the rack and pinion bad. this started as a pwr. steering leak. The pwr. steering would come back before i repalced the pressure hose but it leaked awful.
