1995 Landcruiser bearing noise?

After the death of 92 Previa, I purchased a used 95 Landcruiser.

Bought from a Toyota dealer with full history and limited warranty. Has
155,000 miles.

I've noticed a slight whine which only occurs from between 45 to 70 mph
and only when under load.

Very quiet when coasting.

Hard to pinpoint location but from the drivers seat, seems like from
the front seat area to the back of the vehicle.

No vibration, just annoying whine.

I test drove a 97 landcruiser yesterday for comparison and noticed less
of a whine, but definitely a whine from under the vehicle.

Is this a pinion bearing problem or am I just too sensitive to the
normal driveline noise from these big trucks?

The location of the sound suggests that the source is the transmission,
transfer case/center differential, or driveshaft support bearings (if
equipped with a 2-piece driveshaft). Whining sounds are generally caused by
either bearings or gears. If the other LandCruiser you test drove also has
the same sound, I wouldn't worry about it.
