The shaft in your power steering pump has broken. Your brakes work off of a system known as Hydra-Boost. If this shaft is broken then your steering and brakes are lost. I contacted GM after I had my power steering pump replaced and they sent me a check for the cost of my repairs. My truck was not under warranty or recalled but earlier models (2500HD) had been recalled for the power steering pump shaft. The pump was the same part number for my 2002 2500HD as the recalled years. Good Luck!

1. Air could still be on your power steering system after you replaced your pump.
2. There could be another reason why your having a hard time turning your steering wheel, have your steering linkages, camber, alignment checked, so as to prevent breaking yor new pump again
thank you for choosing fixya!

alright, first disconnect the negative battery cable, we don't want uncle Bob trying to start your truck with you under the hood and you don't want to get hit by anything that has a charge runnung through it. Second, remove the serpentine belt, This is done by putting a 1/2 inch wrench of the back side of the tension pulley and removing the tension. third, you're going to have to borrow, buy, or steal a pulley puller to remove the pulley on the poower steering pump. Then there are the hydraulic lines... the low pressure side can be removed with flat head screwdriver. the the high pressure side is a pain to remove so have fun. IF you can afford it, it's good practice to replace the lines anyway. You may end up bending then anyway. Next remove the bolts that hold the pump in the bracket. There are three and they are 1/2", Reverse the process if you want to put one back in.
