car shakes a bit when above 60, steering wheelshakes too. When braking above 40, mostly on the highways theres a lot of vibration coming from the rear of the car. New rotors, new breaks. Can it be bent rim>wheel off balance> bad tires?

 

Could be either of those. How sure are you the vibration is coming from the rear? Have you tried rotating the tires to see if the vibration moves? What year is your TL? How many miles? How many miles on the tires? Give us some more info to work with.

 

05 tl with 133k miles. around 3000 miles on the tires but my back right tire is really worn out. My mechanic is its comning from the back and you could hear it. he told me to change the rotors and brakes but that didn't seem to sovle the problem. and no I haven't tried rotating thewheels

 

You have 3000 miles on your tires, but the back right is really worn out?

 

Definitely something really funky about that rear wheel then! Did you hit a curb sideways or anything of the sort? Look into getting an alignment ASAP!

 

Depending on how bad your tire is, you may be looking at replacing it. As Polo suggested, an alignment is in order and/or rebalancing of the tires.

 

OP, did you ever get the problem fixed, if so what did you find?
