darcati New Member 16 Member For: 14y 8m 3d Posted 07/05/15 10:56 AM Share Posted 07/05/15 10:56 AM Just came back from a drive to Canberra and have noticed an annoying vibration at highway speeds.It only occurs at speeds above 90-100km/h and only under load and disappears when coasting.The vibration feels like its transmitted through the body and can't feel it through the auto shifter and only slightly in the steering.Apart from Super Pro comfort diff bushes all is stock. Has anyone else experienced this and what was the cause?Otherwise any recommendation of a workshop in Sydney that I can get to have a look at it OTHER than a Ford dealer?Cheers Link to comment https://www.fordxr6turbo.com/forum/topic/90488-fg-f6-auto-vibration-at-high-speed/ Share on other sites More sharing options...

One thing I forgot to mention is the longer you drive the worse the vibration gets. Initially leaving Canberra I could barely notice it but as time went on the vibration was more pronounced, as if something heating up making it worse.

darcati New Member 16 Member For: 14y 8m 3d Posted 08/05/15 04:30 AM Author Share Posted 08/05/15 04:30 AM Engine mount sounds plausible, cant understand how it gets worse the longer you drive, don't think it would have anything to do with wheels as the vibration disappears when coasting.I'm thinking the uni is stuffed and gets worse as it warms up?

May be as simple as a throw tailshaft weight. Gets worse over time as harmonics set in and accentuate the movement. 1 Link to comment https://www.fordxr6turbo.com/forum/topic/90488-fg-f6-auto-vibration-at-high-speed/#findComment-1543638 Share on other sites More sharing options...
turbotrana Member 2,586 Member For: 22y 1m 5d Gender: Male Posted 09/05/15 04:52 AM Share Posted 09/05/15 04:52 AM I've got a slight vibration at around 90 to 100kph in my FG. Its driveshaft related and gets worse when the car is loaded up. With just me in it I don't feel it. WIth a few fat babes in the back seat you notice it.

WIth a few fat babes in the back seat you notice it.My FG is the same. 3 sets of rims, 4 sets of tyres and replaced brakes with new Brembo calipers disc and pads. Superpro diff bushes and still persists. Mechanics and tyre fitters don't seem to pick it up. Thinking of trying new gearbox and engine mounts.
