ohhhh k
i notice the last week that when taking right hand corners in my vt sedan at high revs or putting your foot down during the corner there is a strange noise before it slips out.
strange as in, well best way to describe it is a winding up noise? i replace the diff oil about a month - 6 weeks ago, cause i could.. I havnt change the way i drive or anything else?
it just worries me somethings gunna give way. i dont try to drift it, nor donuts.. just occasionally take corners / rounda bouts fast.

anything else i need to add?
cheers guys.

anything else i need to add?

found something, when ever putting it in reverse from park (doesnt happen drive to reverse) it goes 'PING' when the auto changes gear, this is from the rear end and im presuming that may be diff related? .. its happend a couple times going from park to drive but not often.
