This one solve...
But have another issue.. as previous post or below copy
High Speed Test to troubleshot noise like helicopter / Chopper sound... (geduk... geduk.. geduk) at speed above 145km/h.... it's loud until I can't hear the radio... but car body doesn't shaking... still steadily cruising the highway...
During Inspection at workshop... we put my car on hoist... at 140km/h car still steady... then I spin my car to 160km/h... whole car body shaking... undercarriage inspection by him... he said... T metal coupling like somebody have "usik" and liittle bit loose.. and another coupling near rear axle "pasang terbalik"
Then the foreman, request me to drive up at highway to 160km/h ( car body no shaking) then shift the gear to N..... and I can still hear the helicopter sound until the speedometer down to 140km/h.... then sound disappear and I can listen to radio again...
I give him a call, and according to him confirm my long shaft have a problem...
