Tsikot Tsips!

My 4 month old altis shakes at 35-40 kph. Before and after that speed, nawawala naman, or hindi ko na napapansin kasi higher na ang frequency. I had it checked at casa and they replaced the engine support (warranty claim), but the problem is still there. Casa had a wrong diagnosis on the problem.

Any suggestions and probable reason for the wiggling, vibration?

Thanks in advance,
