Hi Members, I have a Totoya Vitz SCP10 model. After an accident I had to replace rear left shock. Then I had a full body paint as well. But now, my Vitz having a bad shaking noise and it is coming from back of the car. I would like to have your advises and please tell me a good place to do this kind of a repairs in colombo(specially in malabe, battaramulla or any place near) with reasonable charges. Thank you, ISUD
