powersteering fluid squirts out from gearbox at the lid

Asked by for the 1999 Ford F-250 Super Duty
It's probably too big a job to tackle at home but if its any help, there is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate

It is coming out at the gearbox or the pump? You either have a damaged gearbox case or a blockage in the lines somewhere creating too much pressure.
