Hi!

I just collected my EVO 5 in the UK and drove it all the way back to Austria (a 1000 mile drive).

All the bushes on the car have been changed to Ralliart Group N tarmac spec, so the ride is rather harsh.

One thing that feels strange though, is a recurring vibration in what seems to be the drivetrain in 5th gear. Taking the RPM of the engine into consideration an the frequenzy of the vibration I can pretty much exclude the clutch / flywheel assembly from beeing the problem. Also, the vibration only comes on in 5th gear and under load. It is a rythmic, recurring vibration, especially at lower RPMs.

Anybody got an idea what that might be? Centershaft? Transferbox? Gearbox?
Or is that a normal thing, when the bushes are that "hard"?

This is my first Evo, so I hope someone can give me some advice.

Thanks for the answer mate!

Will it do any serious harm to the engine / center shaft e.g. if driven like this?

As I said, I drove it home from the UK to Austria..... :blah:

You didn't changed the input shaft? Mine was weak as you can see on the pisture.
I installed my new pinion with some retaining compound to be sure
