It is currently being handled by Toyota Australia, need to go to who they say at the moment. Only due to the fact that after the regional tech said it wasn't an issue the case was reported to Toyota and the case was closed. I tried going to another dealer and told them what happened and because of it being reported by the tech they wouldn't do anything about it, even emails and calls to Toyota Australia didn't help. Had to put in a complaint with Fair Trade to get them to speak to Toyota. Got a letter from Fair Trade yesterday with this in it "David Cooper of Toyota Motor Corporation Australia Limited explained that they are still investigating the matter and will contact you directly to arrange a meeting." Would of been nice of Toyota to tell me themselves that they are still looking into the matter before complaints had to be issued. Anyway done is done, at least someone from Toyota got back to me.

Please keep us updated.
I definitely don't want a $450 driveshaft collecting dust in my garage.

I will probably give it another go tomorrow and Ill see what I can find related to the vibration.

Have you checked the hub bearing and see if any compliance issues there?

They lied to fair trade and told them the case was open when in fact it was closed. You should inform fair trade of that fact.

Thanks Wayno, done.

same issue . at 200km/h

Went to Toyota today and got to take the regional tech for a drive myself and got to point out exactly what the issue is. After they had it up on the hoist again, he's come back and said they can not see anything, but at a guess it could be a possible imbalance with the rear axles and will replace them to see if that helps. Hopefully in about 4 weeks the parts will be here and we'll find out if that's the cause. At least they are trying to do something about it now.

we had the same problem with our alu driveshaft but our subframe is raised in the back and we needed to tilt the front of the subframe a little bit so the driveshaft would clear the fuel tank.

Our vibration was pretty bad, we ran it on a lift and realised there is a frequency at a certain speed that deforms the driveshaft, it basically moves almost 1/2 an inch from side to side. We put the stock driveshaft back in and it never did it again.

I don't know if the same thing happens with a carbon driveshat but my friend didn'twant to spend and other 1200$ just to try.

So i guess anything that changes the way the rear subframe is hooked creates that with an aluminum driveshaft. It just doesn't seem stiff enough.

It would be nice though for makers of shaft request to add it in description for all resellers, to lessen chance of it becoming unpleasant surprise for customers After purchase.

I also have that issue at around 75 mph with the CF drive shaft and the harder bushings, but only when coasting - it disappears during acceleration. (The aftermarket pinion ring gear has more backlash than the original and the pinion protrudes much deeper into the differential-housing, which may also aggravate this issue).

sorry to bring this back from the dead... frazer, did you end up with a resolution? i have a small vibration at 75km/h and then above 100km/h. i've had it since the car was new (it's got about 9000km on it now), and the first time i brought it in, the tech said it was the stock tires. they did not offer to do anything about it, but i was there for another issue anyway.

i've since put snow tires on the same wheels (stock wheels) and the issue remains, so i know it's not tires. to me, it seems like an axle or a diff. it will happen at speed with zero load on the drivetrain, so it's somewhere in the rotating assembly.
