Hey everyone,

I have a 2006 LBZ that I am getting ready to replace the power steering pump along with the lines, to correct a leak and whine in the system. I have read several ways to bleed the system and looking for the correct way. All Data gives instructions to vacuum bleed the system and then there are other ways that say, put the truck on jacks and turn the wheel from lock to lock. Some say with the engine running and other say with the engine off. Any suggestions? Thanks

Well, I've done them all with engine running, front wheels off ground.
Top off reservoir.
Start engine.
Check oil level and add until at full mark.
Cycle brake pedal twice.
Turn wheel lock to lock w/o hitting relief.
Shut off engine. Wait 2 minutes.
Restart engine and turn wheel lock to lock, to relief each side.
Repeat.
Recheck fluid level.

With a hydro booster in the system, the engine absolutely has to be running.

Here's the procedure I follow (starts on page 4):
