    I just noticed a hum coming from the rear end of the car. It starts at around 40-45 mph. It is a steady sound and does not change when shifting. I can put the car in neutral at 50 and the sound stays. My guess is the rear differential. 86k miles on the car. Any suggestions would be appreciated.



    Quest is a front wheel drive, so there is no rear diff. Any groaning or hum while driving can be your rear wheel bearing.



    I had the same noise on my 2004 Quest. It was the rear wheel bearing. I rode in the back while my wife was driving to figure out which side it was. Passenger side rear. I bought the wheel bearing from Rock Auto online. Had it in a week for much cheaper than the auto parts store. It took about 4-5 hours to do. Not a simple task but if you are familiar with working on vehicles and have a friend to help it is not too bad. Dealship wanted $600 to do. I had only one issue the wheel speed sensor is mounted into the back of the wheel bearing housing. I broke the bolt off. Suggest using a lot of PB Blaster. Had to re-tap the hole. Once it was together, Test drove and noise was gone.
