Power Steering Pump Leaking
Identified as ONE of my leaks. I have tried the first & simplest......Lucas Stop Leak Power Steering. Did not help. Still leak an abundant amount of fluid onto the garage floor (well actually, into a floor pan). What kind of job is it to get at the PSP to work on it? Is this something that can be repaired (gaskets, orings, etc.)? Thanks for sharing. CAB

From a website of a guy that rebuilds them.
What is your rebuilding process?
• The steering unit is cleaned and inspected for external damage and physical function.
• Then it is disassembled, cleaned again, and inspected for internal damage and wear.
• Shafts are reconditioned and polished or replaced.
• Housings are honed, sleeved or replaced as required.
• Parts are cleaned again and prepared for reassembly.
• The unit is reassembled with new OEM (original equipment manufacturer) seals, teflon rings, O-rings, bearings and other parts as needed.
• All settings and adjustments are set to factory specifications.
• Final testing is performed for function, pressure and leaks.
• Standard detailing includes priming & painting the unit. Optional "Extreme" detailing takes the unit down totally to bare metal. Self etching primer is applied then the unit is sprayed with "cast" paint. Custom colors and finishes may be available at an extra charge.
If a unit is non-rebuildable due to damage or extreme rust, the customer is notified of their options:
• Return the unit to the customer.
• Supply the customer with a rebuildable core unit for an additional charge. Core charges are generally what you would pay for a unit at a salvage yard.
• Other possibilities.
Seems easier to buy a new unit.

Pump and hoses are hard to see until you remove the alternator, air pump etc. You may just have a split/perished hose.
Service kits are available for the pumps but they can be tricky fitting them.
Unless you know the age of the parts best to replace with a new or rebuilt pump and all new hoses.
To remove/replace the pulley you'll need a GM power steer pump removal tool as its pressure fitted. You can get them from Harbor freight cheap otherwise you'll need to pay someone to have it removed/replaced. At $20 probably cheaper to buy the tool then you'll always have it. I have one and it did the job just fine.
Its a straight forward job if you have the tools.

My pressure line was leaking where the rubber hose is swaged onto the steel line that attaches to the pump.
The steel line might just be loose where it screws into the pump. There is an O-ring there (if I recall correctly) that may be damaged.
Checking these things is easier and cheaper than buying a new pump (and still having the problem).
