Loud Droning Whine?
Ive got a loud whiny noise that seems to be coming from the back of my car. I have Torque Solutions Rear Diff bushings and heard a drone after the install but searched EvoM and seemed normal, but it has gotten louder after a long drive. Looked at the rear diff and there is def some oil on it, more than normal. Any way I can check it? Thanks

The sound of the tcase has alot of harmonic that travel underneath the car past the driveshaft to the back of the car so keep that in mind. Be sure to use the car stethescope to pin-point where the noise is coming from while the car is in the air just be careful under there.

Is the noise only while you are moving or all the time?
If it is all the time, including while stationery, have a quick read through this thread.

My best guess would be sound from your TC. I had a high pitched whine that would peak at about 80mph. My TC was previously rebuilt by shep, so I sent it back and I had damaged the ring and pinion. Got the new stage 2 upgrade and the car is absolutely quiet. I can actually hear my fuel pump again.
My mustache bar mounts are hard mount and rear diff are upgraded poly.
