    It sounds like a front wheel bearing?
    Or maybe a front CV shaft?
    It used to only happen ever once in a while and go away?
    But it has been happening more and more!
    Some times if I cut the wheel to the left just a little it will go away?

    Does anyone have any Ideas on where to start? I have not found anything hot or loose?

    CV shafts won't usually howl, failure mode generally indicated by rattles and clunks.

    Jack the front end up and start poking around ftw.

    I did and found nothing?
    How does the front axel nut come off?
    How do I remove the front half shafts?
    And can I drive it a little without the half shafts installed?

    Could it be coming from my front diff?

    Not it is doing it more and more!
    How am I going to figure this out? Help!

    Could it be like the front dif pitman bearing?

    Does the front drive shaft come unbolted, from the transfer case?

    Well I made a 200 mile run Friday!
    It started off making the noise every once in awhile till I got it up to speed!
    Drove non stop 90miles then got out and nothing was hot, anywhere, except the exh side rear end and the trans itself!
    I need a muffler and tail pipe and I think that will then be ok?
    I ran it hard on the way home, into a 15-20 mile hr head wind!
    Parked got out and re checked, NOTHING!
    And on the way home no noise!

    Now the only thing I have even seen is that the splines in the front hub have slop or play in them?

    Get it on a hoist with all 4 wheels off the ground in 4wd and have someone get it to 60kmh while you listen with a mechanics stethoscope, easiest way to tell if it's a wheel bearing. Cv axle noise is usually a clunk on turns, wheel bearings get louder with speed. Could be front differential noise too, stethoscope is the easiest way

    Well its the end of April and I have put another full tank plus of fuel through the truck on road, and no more howl!

    What could it have been?

    I would double check the fluid levels in the trans, transfer case, and diffs just to be safe. If you haven't already changed them I would be willing to bet its the same fluid it came from japan with.

    Thanx, yes I put Syn fluids in it and did double check them too!
    Still haven't heard it since!
