    good afternoon!

    Here’s my symptoms. I believe it to be a front wheel bearing but thought I’d ask the experts.

    - road noise that fluctuates with speed
    - seems to have steady hum, fast “wha wha” and little bit of metallic type sounds
    - starts at roughly 25 mph
    - tires are fair but rotated recently with little change
    - when I turn left, the hum increases

    My friend who has worked on G2 Priuses swears that it’s the transaxle but I have my doubts.

    Thoughts?

    Thank you!
    Bobby

    welcome!

    i think you're right. or a cv joint. not sure how to tell the difference.

    how many miles on her? bearings are always the prime suspect. sometimes figuring out which one without a chassis ear is the hard part.

Search you tube for how to diagnose a bad wheel bearing. Then watch some more vids on how to easily do it yourself. I bought two NSK’s off rockauto for about 108 each. Now I need to work on the front ones. Mileage at time of replacement was about 175k. But they have been noisy for over a year.
