I have a 1997 2500 series chevy HD pick-up truck. It has variable assist steering .I change thr power steering pump and the steering box but it still doesn't get hydraulic pressure to steer the truck and there are no codes. How do I solve this problem? Rich
#75 of 139 98 K2500 Suburban w 7.4 and hydroboost by ty5 Jan 21, 2008 (5:57 am)
I am a long time Suburban owner, but till now they where all 1500's with vacuum assist brakes. I just purchased a 98 K2500 Suburban w 7.4 and hydroboost. the brakes are great (compared to my 2 97 K1500's one LT, one is Police issue), but the has a high pitch whining sound that is RPM affected, especially when cold, and the steering is noisy at low speeds, especially at the end of the steering limits, and steering assist is almost non existent when backing in low speeds. Anyone can give me some pointers , before I start to replace the pump or steering components. I searched the Suburban forums but most of them do not have info on 2500 w. hydroboost, as this is more of a Silverado/Sierra feature, and on this forum most reference is for the 99 and newer. Tnx Ty

Replying to: johan (Nov 24, 2006 5:28 pm) I have the same problem, 1997 GMC Sierra 1500 4x4 ext cab, 5.7L. When I turn the wheel approx 80 deg left, there is a sudden sharp drop in steering effort ( feels like wheel came off in my hands). Problem began 3 yrs ago only 1-2 x/year, now almost every time. Also, maybe related, about 3 yrs ago after cold start, power steering remained at full boost for 5 minutes, then fixed itself. During that episode it also felt like the wheel was not connected. Any suggestions would be appreciated. Questions: does this vehicle have a steering angle sensor? Vehicle speed sensor? Anything else that may cause erratic power steering pressure?

I have a problem turning the truck only when its in 4wd sounds like the same problem as #55??But what its doing is almost like snow plowing when I try and turn.The truck will not take a 90 degree turn in 4wd.Like theres a spool instead of a limited slip!I bought the truck new ,never had this or really any other problem and the truck has 48,000.I took a quik look underneath and see nothing obvious!
#78 of 139 2004 HD squeaky steering by mudd_jumper Feb 23, 2008 (6:41 am)
My friends 2004 HD has squeaky steering that has been fixed twice now at about 100.00 a pop. Does anyone know about this or have a diagram were we can do it our selfs? From my understanding is they pull the steering shaft and use a needle grease gun to lube it. So what I am wondering if anyone else has had this problem or know of a better fix or a diagram on how to do it? Thank you for all the help in advance.   Steve

2004 Silverado. Vibration and sound like running mudders at 20 mph and up. Only when going straight and turning to the left. Noise stops with right hand curves.

Replying to: ldsokol (Nov 28, 2007 6:58 pm) I live in western pa and i have a 2005 chevy duramax 3500 4x4 that does the same thing..The power steering system looses power assist when you are moving slow in parking type situations. The bakes get harder to push also.. The dealers have changed the control valve in the power steering pump and also changed the steering box assembly.. it still gets real stiff and looses power assist and has the pump whine.. They told me the tires were low and all the other bs. We should try to do something about the steering problems as these trucks are unsafe the way they are..

Replying to: openend22 (Mar 10, 2008 2:24 pm) I have been driving the truck (98 K2500 Burb. LT 7.4 w. Hydroboost) for 2 months now. The brakes are sensational compared to my other late 90's 1500's with vacuum assist, even at low speeds and engine rev. (idle700rpm) but the steering is very stiff at low revs, a two hand job even for me (6.2" & 240lb), if I can give it some gas, it is OK, so in my opinion the portioning valve that distributes the pressure/power created by the hydro pump gives most of it to the brakes for safety at low rev's. I guess we can play with the portioning valve to give more for the steering, but I do not wan to lose any stopping power!!!! I am just getting a complete GM service manual for it, I will see what I can come up with. Replies to this message: openend22 (Mar 11, 2008 2:18 pm)

Replying to: ty5 (Mar 10, 2008 3:04 pm) gm says that "its a common trait of the truck.. I think its a safety defect. I am also a big guy and it takes 2 strong arms and then some to steer the truck..

Replying to: johan (Nov 24, 2006 5:28 pm) I am curious if the bleeding of the steering solved the problem. I have a similar problem with a seemingly tight front end and say starting to make a left turn and the steering wheel will just let go for just a bit. Or even going down the road straight and with pressure to the left it will do this.
