Whine Between 30-35 mph
Hi, I'm getting a whining noise between 30-35mph when accelerating and decelerating. It just started today. Does anyone have any input or suggestions? It seems to be relative to speed, not rpm. Thanks in advance if you can steer me in the right direction.

Do you notice it regardless of engine-transmission temp?
I'd say it's driveline related. When was the last time you had all the driveline fluids refreshed (transmission, front & rear diffs, transfer case, torque converter)?

I heard it when the vehicle was cold and also after driving for an hour, all on dry roads. The roads were snow covered yesterday so I took it out and never heard anything. I’ve had it for 2 1/2 years and haven’t refreshed any of the fluids you mentioned.

Link to my noise very faint in the vid hard to tell.

Pretty obvious on the lift...the source was fairly obvious too.
