Humming Noise

Humming Noise
I own a 98 4x4 LS Blazer S 10, today driving on the highway I start hearing a humming noise between 65 and 70 mph. Have new sat tires, and today I had my blazer front wheels align, once I slow down the noise stop around 35 and 25 mph. I need help

Could be a number of things ranging from the start of a u-joint failure, a wheel bearing failure, or it could possibly be that your front axle is partially engaged. Does the noise go away when you put it into 4HI?
#3
It could happen, the front axle possibly partially engaged because one day while I was on he highway I saw the 4hi switch was on. How that happen I don't know?
Any answers and yes it did stop making a humming noise for now.

Note on Swartlkk's sig: Common 4x4 problems.. takes you here
If you need more, do a search with the simplest terms, like 'goes into 4hi' or '4wd engages by itself'
Hint: the google engine uses a more sophisticated algorithm.. type
'why does my ______ {and} site:blazerforum.com'
If you want info from all possible sites, type 'why does my blazer ______ '
IIRC this came up recently and the problem was in the switch itself.
Note that this doesnt mean there's anything specific. New/different tires reflect reflect surface textures differently, depending on tread pattern etc.. the deeper the tread, the louder they USUALLY are for a given pattern, depending on siping depth {look it up, wont explain here}. Not to mention the STYLE of tread.. you already know that off-road tires are noisy, right? Hope you do.
