I\'m gonna give you boys a little tip If you're going to rebuild your power steering pump and your trucks components are a few years past their prime, take these words into consideration. After you finally get the main shaft seal off, and by the way you have to start at the very rear of the pump in order to get to the front. Be very careful when trying to replace the shaft bushing. If its an old pump you might just want to leave the bushing in because it might have cold welded itself in. I the smart one I am tried to hammer it out with a screwdriver.....I was getting impatient! Do not do such a stupid thing! cause then you'll have to throw the whole pump away. Luckily I didn't damage the bushing to bad cause there was no way that baby was coming out, and I was able to file it smooth again. So be gentle when rebuilding your pump, and if you can leave the old bushing in. Cowboy Up!
