Mi 3.5 Steering Problem

[JJ The Boat Wizzard]

Hi All

Just Wondering If Anyone Knows How To Fix This This :

When Moving Around The Track If You Try To Steer Past About 20% It Makes A Horible Grinding Noise and vibrates and then spins out has anyone else had this problem

Never had this problem on my 3.5.... but..... Have you checked the CVD pins? If one's loose it might drag around the hub. That's assuming you've already looked for damaged suspension, bend dogbones and anything catching in the wheels.

Hi All

I Think I Have Fixed It I Tightened The Main Belt Up As It Was Verry Slack And For Some Reason The Noise And Vibrations Have Gone Now I Hope As I Only Tested It On My Stand With No Wheels On

Thanks

Ah, You will probably find with wheels on the noise comes back while on the car stand. It's to do with the CVD not being true CVD's so when you move them to a significant angle the wheel, while rotating tends to rock slightly faster then slower during it's rotation. When the whells on it's own momentum cause the CVD to hit both ends of the backlash causeing the thrup-ing noise.
It's somewhat normal, although not healthy to put the car on the stand and do it just for fun!
You should find that there's almost no noise on the track until you're using full steering lock.

Most TC's at least have this to some degree- it's why Xray brought out their ECS driveshafts, but most people agree that in terms of laptime, on the Schu at least, it's not an real issue.
