My car has about 50k miles on it right now and just recently the car has been shaking. Not so much in the steering wheel (Just a bit), but you can feel it through the seat very easily.

I just bought new tires (Less than 2000 miles ago. They are falken ziex ze912 size 225/45/18) and had them balanced and the car aligned. I keep the tire pressure at 35psi as recommended by the technician.

I don't know what it can be anymore. I even took it back to the store and had them recheck the tires for balance. Still shaking and past about 45mph it's pretty noticeable and the car pulls a bit to the right (I know about the pullin issue on the 08 lancers...)



Can anyone help me out with the problem? I want to fix this problem before it costs me $$$$ later on, i'm very tight on cash right now.

 

check wheel bearings....but that should have been done on a alignment. It is speed related so it has to be either tires/wheels/bearings/ and, but most unlikely, a bad cv joint (out of balance) or shaft out of balance. You need it to be professionally diagnosed unless you have experience with mechanics.

 

to be honest. what you should do is process of elimination. find a friend or someone who has the same car. spend 30 an hour swapping tires. or if you have a set of snow tires, swap them on. If you can find out for sure that its not the tires. then you go back under warranty and get the dealership to inspect further. If not, your going to be stuck in limbo and spending alot of time and effort trying to get to the bottom of it.

If their is a problem with the rim or tires, then you can go back to where you bought them and get it resolved at that level.
