If the wheel balance is good then I might suspect the front struts.

They are rechecking the alignment again. If it'* good they said there gonna call GM and talk with them about where to go from here.

(They replaced a Transmission mount. I'm not sure which one but they said it was hydraulically controlled)

(No word yet) * Oil leak -either valve cover or intake, I'm not sure
(No word yet) * Intermittent moan squawk - (still exist) even after the new steering gear that was replaced a few months ago.
(No word yet) * Vibration 60-75 (still exist)
(No word yet but they did here it) * Noise in the steering - when turning left at speeds around 50mph, almost like a humming sound.

I had the same issues over the years – vibration would come and go, balancing would sometimes help for a while. Getting rid of the RSA’* was a definite improvement but vibrations would still come & go - I just learned to deal with it.

My problem was cured by new wheel bearings. I had read on this site that bearings had helped others (thank you BC!)

When I had my tranny done I made them put new Timkens on both sides. The mechanics swore that the bearings were good and my problems were being caused by something else. I agreed – no noise, they felt tighter than my other cars, and it had been 40~50k since wheels were balanced. Afterward the vibrations disappeared. I was surprised by the difference – I was planning on having wheels balanced also but decided I didn’t need to.
So far I have been good for ~5k miles.

NEW NEWS TODAY

* Oil leak -either valve cover or intake, I'm not sure
(Valve covers are being replaced tomorrow)

* Noise in the steering - when turning left at speeds around 50mph, almost like a humming sound.
(Drivers wheel bearing hub assembly)

* Vibration 60-75 (still exist)
(They are replacing the lower control arms. I hope this and the wheel hub assembl fixes it.)

* Intermittent moan squawk - (still exist) even after the new steering gear that was replaced a few months ago.
(They could not duplacate this.)

****** I should be able to pick it up tomorrow afternoon. Cross your fingers for me that the vib is fixed

Nice, looks like you got a lot of headaches taken care of.

Crossing my fingers on the vibration, but thats a hell of a guess.

Thanks, and I forgot to add, they said my tranny pan was leaking. :? If they say so, I never noticed it when I changed the oil (twice already) last time wasn't that long ago. No spots in my driveway either. Oh well It'* covered under the warranty anyways so they can throw as many parts at it as they want

One thing I should add is that the vibration was getting worse again, since the first repair attempt a few months back. I think it may be related to the hub bearing, hopefully. The same time it started getting worse again is when we started noticing the noise when turning left around 50mph. But this is all to early to tell yet, until tomorrow when they replace it along with the control arms.

They said I needed to replace the brakes on the front too. I ask how much. They said $260. I ask what all did that include and was told new pads and resurfacing the rotors I said no thanks I'll do them myself

And thanks again Archon for posting the info on that tsb.
I doubt they would have even considered replacing the control arms. I discussed this with two of the service writers before they decided to give it a try, since nothing else they've tried has worked. They kept looking at the wheel balance, alignment and brake rotors to be the cause. nope, nope and nope lol. They did have a vibration analyzer but if wouldn't read anything even though they feel it when driving it too.

Going to get the car now. They didn't finish it yesterday. They said the also had to replace a coil pack 3/6 and the plug wire for #6. WOW this amazes me that this car has this many issues with only having 26K miles.

They said it still has a little vibration left in it, but has improved a lot. Hopefully it has. The last things they did when they said it did show some improvement was the lower control arms and the wheel hub assembly. I'll post how it rides in a day or so after I get some miles on it. If it has, then it'* one of these two things did help but I don't know which one because they did them together.

Also, when he was going over the list (on the phone) with me he said it was the transmission mount that they replaced. I thought he said motor mount earlier. I'll look at the ticket when I get it, hopefully it has more info as to which mount it is :?

Sounds like they did about $3,000 worth of work to it.

I sure hope you are still under warranty.
That would explain why they/you would agree to do so much.

Yep What'* even funnier about the warranty is that when I bought it with the car a few months back GM denied me on the Major Guard with a $50 deductible after I bought it. When I called the dealer about it they said I can get the Major Guard but it would carry a $100 deductible. Shortly after, I had the Steering rack replaced and I paid 100$ for the deductible. When I went to check out today I was told it was $50 for the deductible plus 59.87 for the new pads I was also getting, for a total of $109.76 The bill did come to a little over $2200 worth of warranty work. At this point I am very glad I bought the warranty. All this work and the steering rack they already replaced more than paid for it. It just suck to have this many problems with such a low mileage car

Car ideals smoother, I didn't realize it was rough until now This was causing a rattle in my overhead dvd player. I thought there was actually something wrong with the dvd unit not the car I was shocked that the warranty covered plug wires but it is funny how they only replaced the on that was bad when their sold in kits.

It was the front tranny mount and the part # is 25731375 it also say mount number 4.081 on the ticket.

I'm gonna drive this to work tomorrow to see how much help this has done with vibration. There'* to much traffic out there right now.
