This has been happening for a few months now. When i'm driving between 60-70 mph my steering wheel with start shaking and you can feel in the gas pedal that there is some vibration. Took it to the dealership and they said I need to get my routers turned. Got them turned and still had the same problem. Then they said I needed to replace my rim(because I had hit a curb and put a big dent into it) so I replaced the rim and got all 4 new tires. Still having the same problem so I just recently took it back like 3 weeks ago and then they say that my front two tires are unbalanced and then they decide to scratch that theory out and said that my back axle is bent. I was told that its called my cv shaft and that I need to know if I have drum or disk brakes to replace my rear axle. Does anyone know what is going on with my car? I feel like the dealership is just trying to get money out of me. But are they right or wrong? I'm kinda curious as to how my rear axle can make my steering wheel shake and my gas pedal have some vibration...can someone explain that to me cause it makes no sense.
