Help with grinding/whirring sound!

[SquareRoot]

@SquareRoot, did you have this problem also? If so I am hoping you found the issue because I am stumped.

No but it's probably bearings somewhere in the drivetrain. Wheel, Axle or carrier. Do you have a 2 piece driveshaft? Also check brake drums for worn and out of round. Metal contracts when cool, expands when hot.

Turns out the noise was coming from the speedometer cable. I took it out and added some cable lube and the noise is gone.
