Serious question...

The issue, which has been going on for a while now and has yet to be effectively diagnosed is a clicking (subtle and slight) sound when turning the steering wheel, especially when the vehicle hasn't been running and especially when moving at slow speeds. Previously, Ive been lead to believe (through research) that it may be tie rod issues, however now I'm leaning towards CV Joint issues. I've had it looked at several times in the past and nothing was found. Additionally, my information center is giving me prompts telling me to get the Traction Control and Stability Control system's checked. Im assuming these systems communicate through the electrical system the ABS uses (wires running out of my wheel bearing hub and under my car) and recently Ive received a message to have the ABS checked as well. Im wondering if these problems may be interconnected. I had the wheel bearings changed a few months ago and noticed one the wires coming from my old wheel bearing hub was frayed and pinched nearly into, I assumed this was why I was getting the messages to check the systems. Replacing the bearings (which were bad anyway) did nothing to fix the problem, so maybe the issue with the wiring is on the car end of the connection, not wheel bearing end? Do those wires run near the CV joint? i.e. if my CV joint is bad now, could it have damaged those wires? Im just spitballing here... Im not sure what might be cause these issues.

To add to these problems, lately when stopped I'm getting push back on my break pedal. Raises or lowers randomly as I hold the vehicle in a stopped position. Otherwise, no actual "breaking" issues. Btw... this vehicle is 4 yrs old. Just found out last week, my alternator is nearly dead as well even though right now my original battery is still good. I love my car.

What is your vehicle and what are the tread depths of all 4 of your tires.

Its a 2006 Grand Prix GXP (the V8 grand prix) the tires are different sizes first of all, 225/50/18 on the rear and 255/45/18 on the front. So cant rotate in the traditional sense and there is an little uneven wear sometimes as a result. That being said the current tires have less then 7k miles on them and the tread all around is pretty good. I could measure but would say at this point the front would be close to each other and same for the rear.

Hmmmm, interesting. You might have some cupping issues with the tires, but you said the tread was fine.

That said, have you had the computer hooked up and see what codes it's spitting out?

Also, have you checked to see if there are any TSB's that regard the front end of the vehicle?

I have an apt. next monday to have it hooked up at a GMC dealership and looked over. Considering I have this apt. I generally wouldn't even post the question and just wait for a diagnoses from them, but considering my bad luck receiving an accurate diagnoses up to this point and/or any real head way made aside from throwing away money, I thought Id see if anyone had any thoughts.
 
Once at the dealer, I'd definitely ask them to see if there are any TSB's that apply to your vehicle.
 
I had that clicking sound in my 82 Buick Skyhawk (real cherry) and one day I was turning the corner to go up the drive way, then there was this "pop" and the car started rolling backwards, even as the engine revved up. I got out and there was ball bearings and metal all over the ground. It was the CV joint.
 
Are you getting a vibration or shake? If so what speeds?

Tie rod ends are really easy to tell if they are making noise. So I would rule that out assuming a reasonable mechanic looked at it. CV seems the most likely cause. A bad CV should not damage wires unless it came apart in which case you would know it was a problem. Its really hard to say what it is with out looking at it. There are a lot of joints that can dry out. I would check how much grease is under the boots of the cv axles. As far as your brake problem it really sound like ABS malfunction which should make a code pop up but not always. Dont let the dealer start throwing parts at your vehicle, that is what they are well known for. half *** diag and then start replacing everything. If they dont drive your vehicle you know they are doing a good diag on your car. Give them really detailed explanation of everything you have noticed.
 
Ok, finally got some answers!! Apparently the noise Im hearing is the intermediate steering shaft, which is no longer simply re-lubbed to fix, rather replaced (Im being quoted 185 parts and labor, not bad if I were to guess). The Traction/Stability control warning lights are coming on, according to them, because the Yaw Sensor needs replaced ( to which they want 415 parts and labor to fix!!) Im not so sure about paying for that.
