Recently I've started noticing a high pitch whine coming from the drivetrain at around 38 to 45 mph . . . then again at 78-85mph. Anyone else having this problem?

I took it to my dealer and their master mechanic said it was normal and was coming from the rear differential I think.

This sound is kinda bothering me and is quite annoying while driving. I just wanted to see if anyone else was having this same thing with their car?

FYI: I have 23000 miles on my car.

 

i have the same noise and i have 5,000 miles....

 

It can't be "normal" if 99% of the cars don't have it!?!

I get gear whine but nothing from the rear....

 

Exactly why I wanna know if anyone else is having a similiar sound.

 

Maybe it's a bad wheel bearing? Are your rims stock?

 

ive got it also, i wouldnt worry about it. I notice mine commin in at about 3,000 rpm in 6th on the freeway. I just learned to ignore it..

 

Yep stock rims . . . the tech said it was coming from the rear differential, so anyone else experiencing this?

 

i have something similar ... i think it's a wheel bearing.

 

I'm curious how to tell if thats the issue . . . and how difficult to you think it is to fix/replace?

 

hahah thats the freakin differential and transmission man cmon dory i guess not all peole know about it. Thats our transmission and differentials and driveshafters working. I love that whining sound man.

 

its supposed to be there in fact all high end stick cars wine, porsches m3s and even my rsx type s used to wihine its the tranny its supposed to do that, or the diff or driveshaft spinning

 

Get some Royal Purple or Shaeffer's gear oil. Should quiet it down some. (Shaeffer's has "climbing" gear oil which keeps the differential running with less noise and wear.) Of course if you are already worn from mileage, it will still whine. It will just do it less. Two quarts will do ya.

Here's a cool link I came across while researching what gear oil to put in the differential. I just switched to Shaeffer's.
