2004 Yukon steering sucks

[Jkittre777]

Hello,
I have a 2004 Yukon and the steering is sooo touchy. I have replaced everything. Even replaced the pump last week. No change.There is no play in the steering, just way to sensitive. I see there is a flow restrictor that will limit the power steering pumps flow to the gear box. Has anyone used this?

I haven't used a flow restictor, but I did swap the large nut on the back of the ps pump that your line threads into, with one that has a slightly smaller hole. haven't had it on the freeway much yet, but I think its a little less twitchy. I also have my caster up to 4.5 I think, and a large front sway bar.

Thank u!! I really think that this is the only cheep fix.

If it is extremely touchy as you say I would suspect a problem with the steering gearbox adjustment. When you say you replaced everything, what is everything? Another thing that can give a strange feel to the steering is when a ball joint is frozen and doesn't rotate smoothly and can give a jerky feeling and most of the time there is a noise associated with that ball joint. If you replaced everything, then can I assume all ball joints were replaced?

It seems to work well for me now. I did alot of other things trying to fix this, biggest fix was a bigger front sway bar, but the smaller orfice in the ps was the finishing touch.

What brand of sway bar did you use?

So I finally got tired of white knuckling on long trips so I fixed the problem 100%. I replaced the orifice on the back of the power steering pump. It’s called a “Mustang 2 power steering flow valve”
P/N 91032918. Made by
“ Speedway Motors”.
I ordered it on Amazon. I am super stoked!!! 100% fixed the sensitive steering.

If you have hydroboost brakes does it also affect that system?

 

[Jkittre777]

I do have hydro boost. I felt zero change in brakes

I have other issues with my steering but that sensitive steering saved my butt this afternoon someone cut me off and slammed on the brakes immediately with no blinker to get onto the 46 eastbound (California highway) from the 101 north (California freeway) because of the touchy steering I was able to swerve and avoid getting a new truck for the low price of insurance payout. With my braking issue things get sketchy when I get cut off

I can't remember what you have said about this if anything, but have you looked at your intermediate shaft, and/or the steering gear box?

 

[Jkittre777]

Yes, I have replaced all a-arm bushings, shocks, pump, gear box, intermittent shaft, new steering stabilizer. Nothing worked except the flow valve. Drives like new again.

V30Crewcab- How's the NV4500 holding up behind the 6bt?

this is the second trans. I broke 5th gear in the first one, fixed that, then I ripped off third gear teeth. so I built another one to put in. its kinda loud in 5th now, so I have a nv5600 waiting to go in next.
