Hi I went for little bit of offroading on the country side roads and muddy forest and drove the car a bit harshly not very bad all I did was a few skids on the mud and when I was driving back home the whole car started vibrating above around 60mph and it's never done that before I took it off roading that day. The next day I drive on the motor way and the car was vibrating again a lot at around above 60mph. Below that everything is totally fine and the suspension goes over bumps nicely like before and the car feels normal. It's just when I drive above around 60mph the shaking and vibrations start. What could this be. It's a brand new toyota land cruiser prado 2020.
