[johnnygsr]

Hi all master & sifu,

I've changed the driveshaft, tyre balancing done but still cant figure it out wats the problem.. plz help.. Ii'm getting crazy driving turbo car at 80kph only. Tolong!!!!.....

Did u go to on wheel balancing ?? or the simple way is interchange ur front rim with ur rear rim .
Another is lower arm bar.

have u checked ur engine mountings?

Issit a strong vibration or a strong pull? What about higher speeds? Does the vibration go away?

i too suggest u shud check ur mountings....
how is idling?

u have to troubleshoot to narrow down the prob. While stationery, rev the engine at high rpms, does it vibrate now? Jack up the front wheels of the car, engage gear and rev, with the wheels moving, does it vibrate now? Driving along the highway, at wat speeds does the vibration comes in? Low speed or highspeed? Highspeed points more to a balancing prob, be it wheels or engine. Low speed might be prob with the tyres, uneven wear.

Hi all sifu.. Thanks for all the advice. Actually I just sent my car for checking on Sunday & they confirmed its not the mounting and driveshaft. After they lift up my car, they said its my front left rim bengkok. He ask me go tyre shop & change the back to front. See how its goes. I'll keep u guys update later. Going to send to tyre shop later. c ya.. Thanks all .. Cheers!!
