Hi, I need some advices on help to identifying the problem for my car... Recently I realised that my car tends to vibrate as im quite sensitive to abnormal noise and vibration on my car. This vibration will only appears when I travel at 90km/h and if I reach 100 is more obvious. The vibrations can be felt from the floor board. When I'm traveling slow at maybe 40km/h, I feel the force back like those arcade steering wheel. That means u need to relax and not hold tight. U can feel the steering wheel turning left and right mildly. Try to imagine as is really hard to put it in words. My suspect is the warping of the rim but I wana hear if there are any bigger issues as I took leave tomorrow and wanted to solve this by tomorrow. I just don't feel good and hope it won't escalate to a much bigger issue. Thks
