Help with whining sound poss trans problem?

Alright so here is my problem i have what i can only describe as a whining like something that is turning or spinning is whining you can only here it when driving, it's most noticeable when at about 35mph steady throttle and around 55 steady throttle its almost like a wheel bearing going bad sound but i know its not because i just replaced wheel bearings a month ago and last week i inspected them cleaned and re-greased them the sound is up front of my truck i have an 1987 ranger 2.9 manual transmission 4x4 i am not using my four wheel drive and hubs are free and i checked to make sure those shafts weren't turning. i replaced the rear part of the 2 piece rear drive shaft about a month ago because u joints were shot and i have greased front and rear part of the shaft i can feel the whining or high pitched sound in my gas pedal and i still feel it when i push the clutch in and let it coast i also can feel it more when i turn truck to the left but no change when i turn to the right any ideas what could be causing this because it seem to be getting worse? any help would be greatly appreciated i am stumped! Could this be a trans problem and if so what in the trans could it be?

"i also can feel it more when i turn truck to the left but no change when i turn to the right"



Sounds like a bad wheel bearing, despite that they are new. What about the rotor dust shield, could that be scraping?

1st of all thanks for answering my post and 2nd because i had just replaced the front wheel bearings and drive shaft i kept thinking it had to be the trans but i was wrong. you hit the nail on the head it was my driver side wheel bearings i must of had them too tight or didn't set the preload correctly. thanks for your help.
