Peugeot 406 vibration. - Quinny
On my 406 at 60mph+,there is a vibration coming from the car.

It works like this....

Vibrate for 3 seconds,then a 5 second gap,vibrate for 3 seconds,then a 5 second gap.....you get the picture?

Now,it's none of the following,as they've all been done:
Wheel balancing
Tyre pressures
Tracking
4 Tyres fairly recently
Rear horizontal link bars.

So does anyone know what it is?

On a side note.A friend of mine hired,through work,a Land Rover Discovery a few weeks a go,and that did the same.

check the drive shafts. Gaiter failure leading to joint failure..

dear sir,

I have a 306Dt that had a similar issue, after doing all the usual thing, I evently discovered it was the bearing on the top of the front strut....alternatively have you tried the anti roll bar..

As for the disco....I would check the anti roll also.
