Hello, and help!
I've just purchased a Fourtrak DX (G reg, 1990) with 131,000 miles on the clock.
It's generally in pretty good nick but between 55 & 60mph the whole thing shakes really badly. However, this shaking disappears when you get up to 65mph and beyond. Very strange and rather disconcerting!
I got the wheels balanced, then swapped them around one by one, but to no avail. Thinking it was going to be more serious driveshaft/axle problem, I took it to a local 4x4 garage. However, they told me that it was a characteristic of Fourtraks and that some of them do it, some of them don't, but most of all they don't know what causes it! They could operate on the car (at great expense) to reduce the shaking, but it would never be cured completely.
Does anyone have any ideas/advice? Do I ignore it and drive everywhere at a hooliganical 65mph (Officer...), or is there something I can do simply and cheaply with a spanner!
