Procedure for bleeding Power Steering Pump

Open Power Steering pump and fill to top..... leave the cap off for this whole procedure...if possible jack the front wheels so they clear the ground about an inch.(tis puts less stress on the pump if it's low on fluid...now start engine....and give it enough throttle, about 1500 RPM is good...observe the fluid level....if you have Hydo-boost brakes, start pumping the brake slowly and turn the wheels right and left, HITTING THE STOPS each time.... do this about 5 or six times in each direction pumping brakes (Brake part with hydo-boots only) turn off engine and observe the fluid... wait 2 to 3 minutes and than add fluid if nessesary lower the rig so front wheels are on the ground......start engine rev to 1500 RPM and repeat wheel right and left ( pumping brakes if HB system) do this about 5 or six times hitting the stops again on each side again...
turn off engine.....wait 2 minutes, check fluid and fill if needed......if fluid seems extra foamy wait one hour leaving the cap off.... after one hour do this proccedure one more time and add fluid if nessasary and replace cap....This should quiet your P/S pump down. If it does not, your drawing air into the system from one of the hoses or fittings.....and loosing fluid somwhere.
