So i replace the left front and the rear wheel bearing and its a lot quieter. But its still humming. The noise goes away when i make a right turn putting all the weight on the left side. What can it be BAD parts maybe?? Should i take it off and return the parts for a new one? I purchase them both at Oreilly Auto Parts. But i did notice the sway bar on the left rear is is apart where it connected (picture below)

 

Are you sure it was the left side? It may be the right? Have you checked the brakes? and yes fix the sway bar end links.

 

Get that sway bar link fixed, and I say the humming is coming from the tires.

 

Tires are Brand new. Im pretty sure its the left side, because when you put the weight onto the left side the humming goes away and when you put the weight on the right side the humming is still there. Wen i say putting the weight on a certain side, im doing it buy switching lane really sharp shifting the weight. Its an old trick i use to do to figure what side the bearing is bad on.
The sway bar end link do they just sell that part? or do i have to buy a whole new sway bar?

 

Found the answer to sway bar end link thanks!

 

Front brakes are brakes are brand new and the rear looks fine.

 

Moog brand end links- get both ends, at oreillys are excellent choice
Fix that and the noise will probably go away
Every time you swerve the car the bar tries to move and its not supported

 

But would that really cause a humming noise???

 

But if im going straight the sway bar is out of play and the humming noise is present.

 

new rear hub bearing and fix sway bar still humming WTF!!!!

 

mechanics stethascope and with car on jacks - spin the wheels and listen

 

I think im going to rotate my tires and see what happens

 

any other inputs?

 

+2... The only way you're going to know for sure is with a mechanic's stethoscope. Even better if you have access to a hoist and can run it in the air. I've been absolutely sure, and absolutely wrong, using the swerve method you described. It is still a good place to start, and works 90+% of the time. It's pretty rare for new tires to be noisey.

 

It was the right rear! quite as a mouse now.

 

Could you elaborate a bit more on the fix? Earlier you said you replaced the rear hub bearing and fixed sway bar but it still hummed. What changed? Thanks.

 

I replace the the right rear hub bearing and the humming went away.
