1995 Landcruiser bearing noise?

Just bought used Landcruiser and I love it.[color=blue]
>From between 45 to 70 mph I have noticed a whine come from under the[/color]
middle to the rear of the truck.
Only occurs under load , very quiet under coasting condition.No
vibrations at all.
Is this just normal driveline/gear noise and i'm not use to it, or is
it diff. bearing problem?
I did drive a 97 LC to compare and it had a somewhat less whining noise
at highway speed.
No oil leaks, all diffs have good fluid levels. What's a quick check
underneath to be sure?

I also have a '95. They are wonderful vehicles, but not particularly quiet!
I don't know what you have; could be a rear-end bearing, carrier bearing, or
who knows what. You'll love that truck.

Took to 2 dealers, one said sounds like front diff, should replace diff
carrier (quickest), the other dealer, the one which sold it to me
claims its the tranny mount that is broken and the subsequent movement
of the tranny against it is causing the resonance (whine).
I'm waiting for the tranny mount part and going that route first . This
is a $250 cost as compared to $2000+ for the front diff carrier.
