I have a track pack car with the 3.73 gears 20,000 miles so far and very little noise from the rear end.
I have the BMR upper and lower mounts and arms (bushings). before I put those in I had no noise from the axle.
Sounds like Im just one of the lucky ones!

I was listening for it again and I think my issue may not be the rear whine like you guys but something else. It's more of a "squeaking" noise that sounds a little bit like birds chirping lol. Doesn't vary with engine rpm but it does with vehicle speed. It sounds like something needs to be oiled up. Can't hear it above the exhaust most of the time. But it is noticeable with the windows down 0-20 mph

Well boys and girls, my rear end whine is 98% gone. So there you have it. Do NOT accept "this is normal" from your dealer. After the tear down, everything was out of spec/alignment. I have to go back to pick the car up with the invoice that has the measurements of before and after. This is costing me $1200. In going to try to fight Ford to get reimbursed since their 2 rebuilds were atrocious.
Now I said 98%...there's still a faint whine between 75-80, but it is SO faint that I can barely hear it with music on. Otherwise it's quiet at every other speed. I also had the trans and rear end filled up with whatever Redline fluid he recommended. The car drives like a DREAM now. Finally!!!!

Hey man I've got a rear end whine issue as well that I've lost a battle with the dealer on. Can you help me better understand what all you had done to your car or rear axle to help eliminate the whine? Was it a new set of gears or just filling it with a special redline fluid? I also ask because I'm going to try and do the work myself so all the info you can share would be greatly appreciated.
Thanks,

A friend of mine bought a used '14 GT with 3.55 gears with around 30,000 miles on it. He asked me to drive it since I have a '14 GT with 3.31's that I bought new. His car definitely had a noticeable whine. Mine has always been fairly quiet, but I put aftermarket lower control arms with poly bushings on it this winter in order to get rid of the wheel hop common to these cars under hard acceleration. I had previously installed an adjustable panhard rod with poly bushings in order to center the rear axle. The panhard rod didn't have an noticeable effect on noise, but the control arms did result in some increase in bearing noise and it also intensified the clunk that is often commented on with the two piece driveshaft. My car has never been lowered, but it does sit about an inch lower than another friends track pack car and that's with the same size tires and wheels. In any case I did get rid of the wheel hop and the increase in sound transmission from the poly bushings is relatively minor.
