"Singin like 44's"

[BigStrip]

I have a loud noise in the front (seems to be a little more to the drivers side). It starts at about 15 mph and just gets louder. It's not a grinding, it sounds more like a universal joint? Mine is AWD, I haven't looked, is there a u-joint on the front also. Someone mentioned it could be a front axel bearing (not a wheel bearing) any ideas?

I'm chasing the same thing it sounds like. I've read alot about the the front carrier bearings going bad in the denali AWD's but everyone says they make noise when you let off the gas and that is the exact opposite of what mine does. Mine almost sounds like a humming noise. Starting to think its just the AWD and its normal. I'm going to change all my fluids (front/rear diff, transfer case) to synthetic Mobil one and forget about it unlee it breaks lol
