Question about Cars & Trucks
When driving about 40mph humming starts and get louder as i accelerate.
Check wheel bearings. Properly jack up the car one side at a time with blocks set in front of and behind the front wheels with the car in Park. Do not set the parking brake as this will prevent the rear wheels from being spun while off the ground. Safety consideration--- Do not get any body parts between the wheel and finder or under the car in case it slips off the jack---- After one rear wheel is slightly off the ground begin to spin it and listen for rough / dry/ popping noises or break pad drag. See if the noise gets louder when you spin it faster or one direction versus the other. Check for loose bearing by trying to wiggle the tire side to side and top to bottom. Pay attention to tire wear. If you find nothing in the wheel itself, the tire might be the problem if the tread is worn oddly. You can change that tire's position with another wheel and see if the noise changes to the tire's new location. Repeat by checking the other side.

I had the same problem with my 2000 Buick LeSabre last year. Took it in and they determined the wheel bearing needed to be replaced. Costs about $300 per bearing, but definitely needs to be replaced as you'd be in serious trouble if the thing went out at highway speeds.

it sounds like a wheel bearing may be on its way out if its real bad u can jack up the car and spin the wheels to hear it or push wheel side to side feel for play in the bearing and inspect brakes and tires aswell
