Hi, I am facing this issue in most of my Toyota imported cars Specially Vitz and Premio. The sounds is too much in cold weather. As soon I hit some speed breaker sound like caachaak comes. The sound becomes less when the car runs for some time. I recently changed my Premio front and rear suspension. The sound got less but it does comes when I hit a speed breaker while the car is still cold.

I know that many Pakwheel members own Japanese imported cars and one of you might have fixed this problem. Please help as i have shown it to different mechanics but no one is able to point out the real problem.
