Guys I have some creaking coming from the suspension (2007 3.6)... when I had it serviced 5 months ago this was a list of things that needed changing (A-Essential, B Desirable) ;

(A) Rear Antil roll Bar leaking (requires change)
(A) Front Anti roll bar leaking (requires change)
(A) Front Diff pinion seal leaking (requires change)
(A) Front anti roll bar bushes worn (requires change)
(B) Freeplay from front lower ball joint and arm rear bushes (requires new arm)

Guys the cost of all this would be quite high.... any ideas what would cause the most creaking or is it all related.. It doesnt always creak its normally when the car has been driving a while.. I topped up the ARB fluid 5 months ago and it really hasnt gone down much at all so I guess the leak is minimal if that matters at all.
