i had mine done a little over 2 years ago....i replaced everything, rack,pump and hoses....cost me somewhere between 1000-1500 dollars
rack=400
pump=200
pressure hose=150
return hose about 35 but u can use tranny cooler line hose from Napa for a lot less on the return line
then the labor...i think it was 3 hours or more for the rack, 1.9 for the pump, 1 hr. for the hoses, then u have the fluid...i also had mine flushed as soon as it was all together
make sure u use power steering fluid and not dexron3 because of the anti foaming agents
