Noise under right front hood

rosieox · 04-25-2007, 01:38 PM

I thought I would run this by you all be for taking it in to Toyota. Over the last 1000 miles my wife and I have noticed a low hum coming from the front right of the car. We have 45,000 on the car, it is not the ICE and it is a new sound. In fact just recently it has been getting louder.

It seems only to happen when power is being applied. It absolutely happens from 68MPH to 73MPH, sometimes we hear it not as loud at other speeds while accelerating, but it's kind of drowned out by the ICE while accelerating.

The hum almost sounds like a loose tread on the pavement while driving but tires are new, 10,000 miles, so I was thinking bearings? But with bearings would it come and go at different speeds? Then I thought something in the electric motor, but I know very little about that.

Any thoughts?

Thanks,
Craig.
