@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.
