How do you change a powersteering hose on a 1992 GMC truck?

First make sure the truck engine is cool.

Take the bolt off the high pressure hose, right on top of the Power Steering pump

You got to jack the truck up and may have to take the wheel off. Look inside the wheel

well and find the power steering rack. Should see the same bolt you did up top, it's

gonna be on tight. Make sure you have a drip pan ready. To put the new one on, start

at the bottom because it can be tricky to align up. Tighten the bolt at the top, then fill

up your power steering fluid. Start the truck, and then turn the wheel back and forth

for 2 minutes to get any air out of the line. That's it.
