I have heard the gear oil can make a difference and have seen it first hand, upgraded gears at low speed turn were very noisiy changed out the gear oil to Royal Purple 75/140 it already has additive and problem solved

 

here is the updated one. galaxie i thought i emailed them to you

I got them, i'll update the TSB list tonight... gotta fix my other junk cars

 

cool thought they didnt make it. never a dull moment i guess

 

I got mine back Friday after they did the TSB. They put in new clutch packs, what a differance ...no more noise.

 

I had it done a couple of weeks ago also. No more noise now.

 

I've got a brand new 2006 Tungsten GT 5-speed with 100 miles on it and it's already developed a fairly loud, low-frequency humming noise inside the cabin when cruising 70-75 mph. Needles to say I'm fairly pissed and I'd like to correct the problem with the least amount of time expended at the dealership. Reading these threads I assume it's the rear-end after doing some quick trouble shooting.

Can someone offer opinion how I should address this issue?

Thanks!

 

bosngt,
I've had it in once for the high-speed hum TSB and it's still making the same noise as before, dare I say even worse! I'll tell you about my experience, hopefully it helps you out.

I'd put a few hundred more miles on the car before you take it in - otherwise they might tell you it still needs to be broken in. (BS, but anyway...)

If you are comfortable with your dealer, and/or have a regular service advisor who you work with, it might not be a bad idea to take a copy of the TSB in with you, but don't act like you know it all. Just tell them that you are having the same symptoms described in the bulletin and you would like to have it "evaluated". Let the service people do their jobs. If they agree that its warranted for repair, ask them if they have the parts in stock or if they need to be ordered. If they have to order them, tell them you'll be glad to bring the car back when the parts are in. Otherwise your car will just be sitting there for a few days.

Another approach is just make an appointment with the dealer, explain the symptoms, if they tell you "its normal" then whip out the TSB and tell them "No I don't think so". If they nail the problem and find the TSB without your help, then smile.

TSB's clearly state at the bottom they are not recalls and they are not meant for DIY'ers, -meaning they shouldn't be in the hands of average joes trying to self-diagnose their problems. Some service departments can get a little irritated with us internet savvy folks who have access to the TSB's. So you'll have to play it by ear and be a little coy.

Then pray they get it right the first time. It's not uncommon that it takes a few tries to get the high speed TSB right.

BTW, I dumped a bottle of XL-3 into the rear axle and no more low speed turning noise for me, but it didn't do jack for the high speed hum.

 

I had the same exact problem with my 05. Right around 10-12k miles it went away by itself. Is that normal I would think not, but knowing that it wasn't anything critical eased my mind, and I didn't feel like having to play games with my dealership with multiple trips.

 

Like I told my dealership, I'm married with 2 small kids, the last thing I need is my car whining too! He performed TSB, whining only changed tone/frequency. Think I'm gettin a supercharger to muffle the sound. Anyone asks "whats that whine", its the supercharger!!!!!

 

Sixty,
I remember your situation and I am now kicking myself. I coulda/shoulda waited another 4,000 miles. Now I'm back to square one. Another 9,500 - 11,500 miles to go. Franks - ditto - whining only changed in tone/frequency - louder and lower!
