Honda Odyssey Noise From Front Wheel Bearings, Replace Both
Honda Odyssey Problem
Average Mileage: 82,257 mi (9,000 mi - 184,000 mi)
Heard loud noises while driving, but thought it was just the engine noise. Took the car to Honda dealer and was told that I need to replace both wheel bearings.
I think the 2005 Honda Odyssey is one of the most problem-prone vehicles that Honda has ever produced.

Humming noise coming from the driver's side front wheel even with engine in neutral. The noise changes with the car’s speed. While still in neutral the pitch of the humming reduces as the car's speed is reduced. The transmission of engine speed has no effect on the noise.

I first noticed that when I would drive downhill, there was some resistance almost as if someone was braking for me. That was probably at 170,000 miles. I went away for the weekend and let me spouse drive the car. I was told that there was a noise when the car was going uphill and downhill. Once I started driving the car, I noticed the noise even while on the street without incline/decline. Took my car to a local Honda and they diagnosed a need to have both front wheel bearings replaced.
