Yes, I told them what the problem was. I thought that the balancing would uncover any bulges or shifted belts, wouldn't it? Anyway, I have an appointment for Thursday. I personally believe that it's not the tires. I know this guy is not gonna BS me, so we'll see on Thu. Thanx for your help guys.

Not necessarily, esp. if they did not look for bulges. Shifted belts usually give you a sway back and forth at slow speeds - ie 5 mph. Seems like they would have looked closer since you had a pre-existing problem. Hope it works out for you Thursday.

there's really not much going on at 5mph. it starts at around 20 and gets worse from there. then it's fading out a little 80 and up. will let you know how it goes tomorrow.

Ok, so here's the results: that guy said that steering rods and everything down there is tight and looks good. he says that it still prolly are the tires. he switched the rotation and claims that it's better now. i didn't pick the car up yet because he's gonna look into it a little more tomorrow. he wants to check the rear axle also...didn't have time to do it today. i forgot what he called the problem i have with my tires, but here's the description: when you do not rotate the tires regularly(every 8k miles or so...and i never did that) you will possibly develop the kinda problem i have and it can cause vibration. you don't have to even take the tires off to check this. just slide your hand over the tread let's say clockwise and it will be smooth. then do it counter-clockwise and if it's rough you have the problem that i have. rotation is supposed to prevent this from happening and i haven't rotated mine in the last 30k. i asked him if new tires would be the way to go. he said that new tires would definitely didn't have this problem, but mine have only half of the tread life gone and that it would be a waste of money. he'll try playng with the rotation and hopefully it would go away. however, this would be the vibration at 70-75mph that shakes the whole car. he said he only felt that. he couldn't feel anything at lower speeds. i told him that it's not much of a vibration, but more like a roughness of the steering wheel at any other speed. i'm not sure what that could be, but he said he would look at it also. because that was never there until about a couple days after the initial vibration at 70mph. wonder if anything could get loose in the steering, but he said it was all tight. after we talked a bit about all this and that he said that he wanted to tell me that it actually rides very nice even though it had a vibration. he basically complemented my car. he said that he drives a POS Toyota and has a GMC truck so he can feel anything in those two. that's why the ride in the Aurora seemed so smooth even with the vibration. anyway, we'll see what's gonna happen tomorrow. will let you know.

Yeah, thats true, the tires will develop a "cupping" pattern in them if not rotated. I trust he won't be looking for an axle in the rear, there is none Sounds like he does know what he's doing and the rotation thing may very well help you. :-)

i wasn't sure what to call the rear end part so i called it an axle. that was my stupidity. he does look like he knows what he's doing. however, if nothing helps i will be looking for new tires. i've had my eye on the Hydro Edges. How do you like them? i wanna stick with quality from Michelin...have been very happy with them.

I would also (as a previous poster mentioned) recommend checking the front wheel bearings.
On another GM product, I had what I thought was tire noise with a little vibration. But as it got worse, I felt like the frequency was too high to be tires. It was making noise that you could hear accelerating starting at ~20 mph. And when decelerating, you could hear it all the way down almost to a stop (less engine noise decelerating so it was easier to hear at the low speeds). Since it was definitely tied to wheel speed. There no change if I shifted the transmission into neutral, so it wasn't tied to engine speed.
Tires were overdo for rotation (maybe had 15,000 miles), so had them rotated. No change.
Had front end alignment checked & front end looked at. No problem.
Pulled the front wheels & checked the hub/bearings. Grind, grind, grind....
Dang expensive fix. Could only find the hub/bearing/ABS sensor assembly (not just the bearings). Over $300 a side for parts. Ouch.

how do you check that? i told him about the wheel bearings before i left the car there and he agreed with me that it could be it. but today he told me that everything mechanical down there is tight and fine. also, i really don't hear any noise. i thought i did, but it was just me. i even drove with an open window(accelerating/decelerating) and didn't hear anything.

If you aren't hearing any noise, it isn't the wheel bearings. Sorry that didn't help.

ok, so the baby's back. the only thing he did was changing the rotation and cutting the rear rotor a lil bit. it was warped a little and you could feel it when braking(not bad at all, so didn't even mention it to him). the rotation did a lot! I have no more vibration(real vibration) at high speed. The other vibration i talked about was and still is at any speed. however, it's really not much of a vibration. the steering wheel is loose and there's creaking sound coming out of the column when cold. i think something in there is loose or not lubricated and thus making the wheel a little shaky. it has nothing to do with the steering or the tires. so problem solved. the ride is sooo much better now. and i'm not nervous that i'm gonna lose a wheel or something:) i'll take a look at the steering column prolly this weekend and will see if i can see something.
funny thing. the guy really liked my car. he said that he thought the car was riding absolutely great and that was before he fixed the vibration. he said he (obviously) test drove many many cars, but he never drove anything like this. i was just like oh yeah, i know.
from now on, i'll be rotating the tires every 8k or so. i might have to buy new ones anyway...doubt there will be another possible non-vibrant rotating option.

I guess I am not following, did you ever actually have a road-force-balance done?

yes. i paid $75 for balancing at my local dealership. they ran it on the Hunter GP9700 or whatever the name was. didn't do a thing. i didn't explain the problem accurately. my tires have developed a cupping patern, which started causing the vibration. the guy at the dealership didn't care for checking for that and just rotated the tires as it's supposed to be done (fronts straight to back and backs crossed to the front) since he crossed the fronts the cupping pattern made the vibration even worse. my guy swaped the fronts so the cupping wouldn't make any problems and the whole vibration went away. i hope it makes sense also, my guy checked the balancing and said it was perfect.

Now, some may not like this so I will mention it, but only in the rain do you hear some noise from these tires and that only occurs on certain roads, not all Otherwise, they are very nice, they cut through the rain and keep the traction right there - sweet
