2008 Prius brrmmppmpp noise front driver side

Sure sounds like a bad strut or sway bar link. When was the last time you replaced those?

 

You should be able to kind of duplicate that with the front wheels lightly off the ground like say about an inch both of them and the long metal digging or pry bar I use a digging bar It's solid iron I put it under the front tire and then gently bounce the metal bar up and let it down but do it relatively quickly like your pumping the jack on a floor jack and quickly and see if you can duplicate the similar noise and then if that works then you kneel down on the ground while your friend does the lifting sometimes you can do the lifting on the ground if the bar is not really too heavy but a digging bar is quite heavy and then you'll be able to look while they're bouncing the wheel up and down then go do the other side.

 

If you're jacking up with an iron bar a 2x6 will bend before it actually starts smacking things enough to make things happen generally speaking lumber dimensional lumbar is not ideal unless you can get it up under the tire on its side The board that is the part that doesn't deflect if it's flat you're bending the board before you lift the tire practically That's why I generally use something like a digging bar it can make serious lift movements on the car if you're not careful in the cars too high you can tilt it right off the jack if you're afraid of that lift the one side at a time you're working on and power up and down on that wheel that's up then you have no risk of anything happening pretty much but you really have to be lifting up and down on that thing You got to realize you're lifting up on a spring that's made to hold up you know 900 to $1,100 lb or something
