I have a 2002 Toyota prado, and today it started with a massive vibration. I was driving along the highway at 100kph when it happened. I pulled over, and checked that all the tyres were full, and that the wheel nuts are tight, then continued. The vibration started again when I reached 60kph.
I stopped and checked for damage on the tyres, and that the suspension and steering did looked good. I checked the weights on the wheels, and it doesn't look like any have fallen off. Shortly I will go and get a wheel balance done, but does anyone have another idea?
