Drivetrain whine. Please advise.
Hey guys. I'm getting a loud whine from my drivetrain and wanted to see what everyone thought it might be. It whines when i'm accelerating/when there is load on the drivetrain. It's a high pitched whine, not a grinding. I get it in all gears and the faster you go the louder the whine.
I changed tranny fluid and it looked good. I changed diff fluid and it was burnt. There were also some metal shavings on the magnetic drain plug.
I'm under the impression that it's the diff but the only thing that has me second guessing myself is that I also hear a little whine when I change gears and I feel it in the shifter.
Your help and advice is greatly appreciated. Thanks.

Resulted in the replacement of the rear transmission carriage on my 18,000mi
2003 with new one. Dealer charged me close to $2800.00. Dealer rebuild about same cost. Figured I'd go w/brand new.

The way I understand it....when the ring and pinion go, it also affects the bearings on the torque tube (driveshaft) which results in whining in the rear end and feeling it thrugh the shifter and hearing noise under the console. This just happened to me this past month.

Go with 3.90's and don't look back. Perfect gear for a daily driver/weekend warrior/ long road trips. I wish I had gone with 4.10's, but I like a lot of gear.
BTW, call England Green in Houston for an RPM special with install.

Holy expensive repair Batman!! I just bought a used 3.42 diff on here for $600. This just proves one of the side benefits of someone that enjoys/has the capability to work on their car - not dealing with expensive stealership labor rates.

Iv'e been getting a tad bit of drivetrain whine since april, Ive had it on the lift at my family's dealership and noticed a little leaking from the rear diff, after looking at it with a couple of mechanics at the shop we concluded that the leaking was so minor that it wasn't worth the effort to replace it. So I just keep an eye on it, the whine isn't that loud and the car still shifts and drives fine. But I'm a little different I have access to a shop and mechanics to fix it if it gets worse.

Wish I had the time to learn, but have to work long hours to afford this toy.
