Mine does the same. Holden have informed me it is actually the LSD clutches engaging and disengaging. An oil change with the special additive does quieten them down.

Berg is right. My VX does it aswell

yep just had this done to ours, changed the oil and added the additive and all sweet.

its just the LSD my VX does the same, its normal, don't let it worry you, but as said there is an additive to quieten it down i haven't bothered my self.

whats the additive

If it's a LSD,Castrol SF-XA or Penrite SIN-80 80w/140 or Nulon 100% Synthetic 80w/140

Think the LSD is the same as the Ford one,used Castrol the first time and just used Penrite which I think is quieter (LSD clutches engaging)

All the above products contain the additive
