I have a 2005 scion tc with 105k miles on it. I have road magnet lowering springs with my stock shocks. I was driving on the highway and my car start to feel like it was shaking apart trying to give it gas over 45mph. I got it to Toyota and they said my CV boot fell off and I needed new axles. I had them install after market ones since I really didn't want to spend 2 grand for the Toyota brand ones plus labor. After they installed the aftermarket axles they told me that there way a small rattle and there is after 25-30mph and then goes away. I had them look at it again and they gave me another pair of axles, only to find out it was still making that rattle(shaking). They told me due to my lowering spring that it was causing the axles to come close to my transmission causing that vibration. Any suggestions????? I have a 12month warranty with the new axles.

 

Most likely a load of horse ____. Unless your springs are installed incorrectly, or your shocks are shot, you shouldn't have any problems. There is something else going on that they are not willing to and/or can't fix. Take it somewhere else.

 

I went ahead and ordered the Toyota Axles now the car feels great again. I guess not all aftermarket stuff is always the best
