Hi All,

A friend of mine has an X-type, 3.0V6 4wd, automatic transmission, with a strange problem while driving. The vehicle is making a wobbling movement, continously rolling over it's length-axle.

The movement is very strong, iteven makes your body shake. It's quite low-frequency, probably between 0.5 and 1 Hz, in any case much slower than a vibrating wheel or axle.

The vehicle does it while driving in a straight line, it gets worse in right corners, and better in left corners.

For the rest it doesn't pull to one side, or making strange noise. Dampers are already replaced, but didn't make a difference.

I have the feeling comes from the rear-side of the car, but not completely sure.

Is it a known problam, or does anyone have a clue?

 

thnx for the reply. Soon we will try another set of wheels, but I don't think that's the cause. The vehicle is continously rolling, slowly, it's not a vibration, like from a unbalanced wheel.

 

The wheels are all thightened well.

Something with the swaybar could be an option, we have to check that in a workshop.
