    I am not sure about the trouble you are having, but i have a factory manual on the later blazer and it says DO NOT drive with the hubs locked and in 2wd Damage can occur. It also says DO NOT drive in 4wd without the hubs locked Damage can occur.

    That sound you hear is the whole frint drivetrain spinning. I notice a difference when my hubs are locked and I go by a building or something that'll reflect the sound back to me. As for damage occuring due to locked hubs. If you drive on dry pavement and have the wheel cut all the way and just do circles for a long time, I can see damage happening. But I'll drive with my hubs locked on the road all the time because it'll snow one day, then the roads will clear the next and I'm lazy.

    I guess what I'm trying to say is that if you leave the hubs locked for a day or so at a time, no big deal, but if you were to lock your hubs and never unlock them again, excessive wear and possible damage will occure.
