Just started driving my truck recently, and noticed a humming sound while driving down the road. As first I just assumed it was the tires humming on the road, but Im starting to think it might be a different issue. I am running 305/70/R16 BFG ATs, and didnt think they should be loud enough to hear in the cab with the A/C and radio going. Im starting to think its the wheel bearings, but the sound doesnt go away even in turns. Its sound is dependent on speed as well. It gets louder the faster I go, and doesnt change if I get off the pedal, unless the truck is slowing down. Its not really noticeable until I get to around 40-45 mph. It also doesnt go away if I hit the brake pedal, so I dont think it has anything to do with the brakes.
Could it just be the tires making that noise? They only have about a thousand miles on them...if that. I dont want to start just throwing parts at it, since I know the nickle and dime stuff gets expensive after a while, but at the same time I dont want to ignore it and have it get worse.
Finally took it to the shop today. Driver's side bearing had failed. When I pulled it off the truck, the little metal bearings inside fell out all over the ground. Looks like it just fell apart inside and thats where my noise was coming from. Also ended up getting rid of the ABS light that I have had on since Ive owned it.
It was a LOT easier to pull than I expected. Took me about 2 hours from start to finish. Very satisfied with the lack of front end noise from the truck now.
