Any one else had a drama with a noisy/vibrating tailshaft?
My Turbo is on its second tailshaft. It developes a "pinging" noise on change of direction.(ie going from forward to reverse/reverse to forward) The dealers have replaced the shaft for the second time, which cures the problem, but only to re-surface within 4-8 weeks, after which time I try to put up with it until it finally drives me mad. I've not gotten any feedback from the dealers in regards to the cause (they never are interested!)
There is also a vibration which developes, but only after a long drive at sustained high speed. (110 kM/h +)
By the way the car is a manual, does not get thrashed, has not seen a race track, and only had one (yes only one) high rpm (ie;2100rpm) standing start!!

OK, I'm now getting that loud 'Ping' noise during a change of direction. I am also getting vibration at highway speed, but had thought it was just a wheel problem.

That noise is insanely loud at times - when I select reverse in order to back up a hill, it is quite startling. The re-selecting a forward gear it happens again.

Time for an unscheduled-service visit.....

Take it back to the dealer and tell them to look at your diff (probably an LSD),
It seems that something is causing the tailshaft to become unbalanced, maybe the driveshaft bolts are loose or the balance nuts on the driveshaft bolts are fitted incorrectly. The pinion flange on the diff could be loose.
Take no crap from the dealer, tell them that the problem will lead to the gearbox crapping out if it isn't fixed which will cost them more under warranty

i have a 2003 BA xr6 5spd man. As yet i have not noticed a tailshaft vibe but my diff appers to have a problem like to much backlash, it drives me nuts . the response from the dealer was less than i expected. I now hate driving the thing. never ever again a falcon

Our BA XR6 is the same, just went in for a tailshaft balance, still has not rectified the problem, the car managed to spit all its oil out though and require the engine to be removed to repair it.

So frustrating for a brand new car, we're thinking bout selling it. Cant stand it, never buying another Falcon again.

A single clunk on change of direction is backlash related. If a new shaft fixes it for a time, then it will be wear in the CV joint causing the noise.
