The Mazda box is ok, and if the ratios work for you, I'd leave it.
Ford also installed the ZF behind the 300 and 351w, so you could bolt one of those in if your trans is bad. It is a heavier trans with a lower first gear. (5.7x vs. 3.9 apprx for your trans)
But first, oil and all the other stuff in the prior post.
R&R of the Mazda isn't terribly hard, but I think you need a press for some bearings and gears.

no flaming for spelling corrections? i am surprised. a rear end problem can also make that sort of noise on the highway. but definitely check the tranny fluid before you start tearing things apart. wheel bearings tend to rumble when they go bad, too. there's a lot of other things to look out for as mentioned.

Oil for the M50D is ATF, Mercon V. Others have used Redline, 10w-30 etc:

As for the rumble at 60, do you have it in 3rd, 4th and 5th? Or just in one gear?
If in all three gears, look at your driveshaft and make sure it isn't bent or dinged. Check the wheel and pinion bearings. All should be about the same temp after a drive. If one is really hot compared to the others, you should replace it.
The rumble was there and stayed the same after the u-joint job?
Same with tires?
