The second mechanic, I dont go to the first one anymore.

 

Updated for you guys.

It seems the problem is coming from the left front wheel only. We replaced that hub with another but there is still a vibration. Mechanic also pointed out that the bearing growl noise is still there. I hadn't realised as I was so caught up with the wobbling. Themechanic is saying that he believes the knuckle itself where the bearing goes in has become worn and is giving the vibration as the bearing turns. He said the bearing is supposed to fit tightly into the knuckle but sometimes the knuckle begins to wear. The vibration gets considerably worst under braking and car pulls to the side. What do you guys think?

 

Maybe you should check the brakes. You may have a badly warped rotor possibly caused by the original severe wheel wobble.

 

I had already suspected rotors but after changing rotors and pads the problem was still there. I forgot to mention that the car dips to the left under hard braking and feels like the left wheel is about to break off. And even after replacing the wheel bearing with a new one the growl was still there. Steering is also slow to respond sometimes. Power steering fluid is good, no noise from the pump. Wheels have been balanced and tires are good. Anymore ideas?

 

if you have a growl it mowst likely needs a new bearing.

the wobble could be the bearing or a tie rod end wither outer or inner.

 

When the car goes LEFT when you brake hard, that could mean that the brake on the RIGHT side is weak.

If you can hear the noise when you jack up the wheel and turn it by hand, take the brake caliper off and try the test again to make sure it's not the brake. Also it could be a CV joint.
