Hi Scotty! I have an 03 Prius. Great car and it is in perfect shape. However, while going down the road I hear a whining coming from the rear. It stays the same whether I make a right or left turn. It seems to present at around 30 mph and stays loud on up to 70+ mph. There is no clicking and the wheels seem solid so far. Do you think it could be a rear bearing?

Sounds reasonable, could try rotating the tires if you suspect a tire noise and see if the sound moves.

Thankyou! That is actually a great idea. I'm glad you responded because I would have never tried to do that first.

Yep, I always to the free stuff first!
