I have been told I need a steering pump by one mechanic and a steering box thingi by another. One told me I have rack and pinion steering. I had immediate failure when turn to the left shaply while braking. I did see a recall but when I called GM they could not find it. Please help me. Thanks Christine

It is an 8 cylinder red sporty truck. I can look in the book if you need more info. I think it is a 150. thanks so much for a reply, I put power steering fluid in it yesterday and drove it around the block, now my arm is hurting really bad. It was low, this makes me mad because "Valvoleine is supposed to check fluids when they change oil. Thanks again

2000, you must think I am a real dingbat. Sorry, I have been writing my memoirs all day for class tonight and freaking out a little. Oh I did find a recall on exactly the same thing at a auto site but when I called GM they said it was not in their computer. Go figure.

Re: GMC Sierra Power Steering Failure	Sign In

I’m not sure what to say without seeing the truck; I did look through the service bulletins that I have here and nothing got my attention that would address this.
This may have something to do with the variable rate steering that is on this truck; as in not allowing full power assist at lower speeds like it should.
The way variable rate steering is suppose to work is that when the vehicle is not moving or at very low speeds the pressure from the pump is sent to the steering gear at full pressure. This makes the steering wheel very easy to turn but at higher speeds as in driving out on the highway, a computer will start to restrict this pressure. Which will require more effort on your part to turn the steering wheel. They do this to give you more road feel and too increase steering stability for things like lane changes. The harder it is to turn the steering the slower you’ll turn it; lowering the chance of fishtailing while making abrupt lane changes because of over steering.
Whatever is causing this to happen to your truck get it in to a garage and have it diagnosed. It maybe something in the steering linkage that could either come apart or jam the steering; leaving you with no control over the thing.
As for you being pissed at the fast lube place you get what you pay for! If a power steering servicing wasn’t the gouge (sorry "service") of the day when you were there; then they weren’t interested in checking the level. Do I have a dislike towards fast lubes; well not all of them but most of the young people that work at these places are sent through a barrage of seminars on how to up-sell a service not on whether the vehicle actually needs said service.
At times with these places it’s like they have a roulette wheel in the back room with all the different services they provide labeled on it. Spin the wheel wherever it stops is the service they push that day. LOL
Sorry for going off topic but it makes me and the rest of my trade look bad when things like that happen; sell people what they need not what you can!
