Bad shaking I cannot figure out

Hey guys I got a big problem I'm almost ready to scrap my car and get a new one...

I have a bad shake in my car between 45-70.
I have brand new pads and rotors
Tires are balanced and alignment done.
Brand new shocks and springs.
Fresh brake fluid and brakes bled.

The shake is also intermitant.
Someone told me it could be the axles
Someone also told menit could be the bearing

Check your axles, they shouldn't have any play in them.

Jack up your car, grab the wheel at 12 and 6 and try to move it. If it does, bearing.

3 and 9, shake it, could be tie rods.

Only if something is loose and has easy play, if you're moving the other wheel, you're pushing too hard.

Could be a bent wheel.
Have you tried putting the front wheels on the rear to see if the shake follows the wheels.

Axles have no play.

Wheels have no movement at all.

I think it could be the new rotor might just be defective cause now i noticed when I brake its more noticeable and the more I brake the more I feel the shake...guy I know thats been a mechanic for 15 years said I should have them cut even though they are still newish (less than a week old)..

Also when I drive in the am everything is fine but if I make a slight left turn like a curvy road I start to feel the shake...any ideas guys? I'm ready to scrap this car :-/

I know my one tire has a slow leak, and when it starts getting too low, my wheel shakes until I fill it.
