I'm Awesome
This is on my 98 Tahoe. I had a leaking power steering pump and gear, so replaced both of those along with the power steering hoses and steering linkage (idler arm, bracket, tie rods, pitman arm). I had no issues with power steering assist, it just leaked.
It now has very little power assist at idle. Rev it up and it’s much better. I put my old power steering pump (with EVO) back on and it was no better, so I figured it had to be a bum steering gear. It had perfect assist before all of this was replaced.
So I put the new power steering pump (Delco reman with EVO bypass) back on and core returned the original. I then warrantied the steering gear twice, so I’m on my third one. It cannot be the steering gear.
With the wheels in the air, it’s not bad. Nothing binds and you can turn it lock to lock with one finger. There are no bubbles.
With one wheel on the ground, steering assist is roughly halved.
With the wheels on the ground, I get a howl as soon as the wheel is turned. It sounds like what you get when you hit the lock stops and the relief valve opens. The fluid has some little bubbles at that point— not quite like beer foam but close.
Here’s a video of the noise.
Could this be a bad pump or maybe a bad (restricted) hose since it works when revs are increased? I never swapped my old hoses back on to test it because I didn’t want to contaminate the system.
