Hi guy, I have done follow step in order to eliminate vibrate problem that occur on my car. 1. Tyre balancing.2. fit in centric cone.3. on wheel balance the tyre. after I've done above step, the car behave much better BUT only below 110km/h.Starting from 110km/h my car steering start to vibrate, after I accelerate pass 160km/h..the car feel like going over those speed bump and I really can bear with it anymore and can't push the car to higher speed. is this suspension problem? But even "kaput" suspension won't behave like that. :angry: What else could be the problem?The vibration doesn't seem like balancing problem anymore becase if it's balancing problem, it won't vibrate such a violent way. Really can't enjoy driving my UDM with this kind of problem. :cry:
