If you can hear woh woh sound especially when you drive in straight road, it should be bearing problem. This problem happened in my Vios 2 months which costs me RM200 (Kluang, Johor).

If you hear loud "tuk tuk tuk" sound especially when you drive across a hump and bad condition road, it should be absorber problem. It might be driveshaft problem too. This problem happened in my Nissan car almost half year ago which costs me around RM800 (workshop is located in Subang Jaya).

the mounting rubber, lower arm bushing and some others bushing also might be affect also...

Your situation is same with my Nissan car. It might be absorber problem.

I cannot give any assumption as I am not from automobile mechanical background. You should go to several workshops in Subang Jaya and Klang area to check your car.
