It could be just axle bearings or pinion bearings.the first is cheaper either way i would have the problem checked at a reliable shop just in case the rear end needs repaired so it does not look up .please rate this answer thank for your question.

Sounds like the differential is in need of oil,This could be a $20 issue.Left as is and the differential goes bad, About $300 from a junk yard or $1000 new to replace.

Hoping it's not too late,Priceless


Please rate this a fixya

Loud humming noise front end moving


While driving, slightly turn the wheel left and right, to see if the noise gets louder and quieter. If it does, you have a wheel bearing that is failing. Then you need to isolate which side is making noise and have it replaced. SOON

I have a 2005 Chevy Trailblazer and it is making a loud humming noise coming from the rear end. What could that be making the noise?


ok it could be two things. it could be rear wheel bearings or a rear diff. If its a high pitch wine then its worn gears in your differential. its needs serviced or replaced. If it more of a rumbling or grinding hum, coming only from one side or both) then there are bad wheel bearings.

2005 mini cooper has loud humming noise from rear when driving above 40 mph. Any suggestions on what this could be


I had a similar issue and it ended up being a broken wheel bearing. I even ended up having two, one was broken on my front passenger side, and one broken on my rear driver side. The part costs about $280.00, but could cost around $400.00 with service repair. The noise of a broken wheel bearing can sound like a humming, and over time it becomes louder. The car can be driven with a broken wheel bearing, but doing so can eventually lead to other wheel/tire maintenance. MINI's endure this commonly due to their low profile to the ground. Here is a forum on further issues experienced, including the bearing, and efforts towards recalls. http://newmini.wordpress.com/2009/02/17/mini-cooper-power-steering-failure/#comment-884

Rear driver wheel has light reubbing noise when car in motion goes away when brakes are engaged. Is this brakes or barrings problem? Cost of repair?


hi this sounds like your brake pads have worn, or the brake shoes as well, if you have drum brakes on the back it will be shoes, if disk brakes will be pads+shoes (inside the disk) if it was the wheel bearing you would hear a loud humming noise not rubbing noise, is it a metallic rubbing noise or a rubber squeaking rubbing noise? just check condition of tyre on back if it is the squeaking rubber noise cost will depend on where you take it and if you do it yourself, possibly $40 to $50 at a garage/auto shop or possibly $20 to $30 if you do it yourself, this just depends ...hope this helps

Humming noise


My 03' avalanche was making the same huming sound. After checking everything that could possibly be making this noise from tires to wheel bearings to brake shoes draging and four different pro garages giving me four different answers, I finally checked the rear differntial only to discover fluid slowly seaping out of it. I'm told more than once' that this is an ongoing problem with some rear ends on these model trucks but chevy or GM will not take any responsabilty or acknolage any problems exist. This little non responsible action finally ended up costing me over $2300.00 out of pocket... SO' have the rear axle bearings checked and serviced asap before this happens to you...

Humming


Chances are it's the tires rather than the engine.
Does the hum diminish if you back off the accelerator? If yes, then look at rear axle pinion bearing. If no, then feel across the tires. They should be smooth across. If they're rough, they will make a loud howling noise.
