I have a Suzuki Jimny 2007 model. When I drive at 80 kmh, the whole car shakes violently. It has the same vibration when the speed comes back untill 50. I spoke to my garage guy and as he said I polished my king pins. After some time the same vibration started again. I could not find the reason for this problem from any of the garage guys. Can anyone help me with this please?
If this is a Jimny, then this is sadly expected. There are stories of people replacing the gearbox mount to resolve the issue, however I never got that far with my Jimny.
I had replaced a number of bushings, got an alignment, and new alloy wheels, however the shaking was still there - just far less pronounced. Like you, the vibrations were fairly violent at high speeds
