I have a 02 tls every time I hit 40 mph my car vibrate its not my tire because i just got it rebalance with brand new tires also just got an alignment. This started happen ever since i lowered my car, can some tell me what the problem is?

 

Check the axle. Common problem on lowered cars.

 

so does that mean that i need new axle

 

Could also be your upper control arm and ball joints.

 

id like to say axles or balljoints. Also check your tie rods.

 

I have the same problem. I am going to replace the wheel bearings first, if that doesnt fix it, im gonna replace the ball joints up front.

 

i think im gonna check my ball joint first

 

you should have some type of noise coming from the ball joint over bumps if it were bad enough to cause vibrations of some sort. My guess would still be rim/tire balance related even though its new tires or a axle.

Did the vibration happen right immediately after the drop?
Did you put new tires on because of the vibration or were they already on?
Have you tried rotating the rear tires to the front to see if it makes it go away?
