Don't mean to bring up a semi-old thread but I guess no one has been able to fix this problem yet....

 

I have the same problem on a totally stock '05 LGT w/ auto and I get the same sound regardless of temp. The other day was 32 C (about 86 F) and I still get the sound which only seems to happen at speeds over 80kph (~50mph).

 

 

It's driving me nuts, literally!!

It's probably the same issue I have, which is not what people are describing in this thread. Here's the problem I have:

That's the range of the sound, though mine extends somewhat above 3k. I haven't found the post that you're referring to though. Have a pointer?

edit: Ahh, I found it. The suspicion is that it's the center driveshaft bushing

5th gear noise is a different drive-line noise.

 

Edmundu has talked about it.

 

I can get it too, but it is not what this thread is about.

I'm not talking about the fifth gear whine that Edmundu talked about ages ago. I'm talking about flooring it in 5th gear, and around 3000 rpm, the back of the car sounds like it wants to shake apart. Part throttle is just fine.

I'm with Gmachine. 1-4 is great. No noise. 5th is bad!

I've got it bad in 5th gear. A lot more noticeable as I've added more power
