OK guys, my 05 WH GC CRD now has a diff whine. (I think) Its not too bad but worse on override and lift off throttle. Definitely sounds like a diff to me its more of a medium high pitched harmonic sound...if that makes any sense. Question now is what do I do about it? I have read some posts which seem to be saying this is relatively common and the fix is an "overhaul kit"?? Who does this work at a reasonable rate within striking distance of Nowra NSW?
regards

ps: I know I am getting old and deaf but I can hear it pretty good
A couple of tips,
Check the fluid levels! Fill up to the plug
Take it for a spin in full time 4x4 feel if the rear cover is any hotter than the front one.
It's far more likely low or incorrect fluid than an actual problem with the diff...
Just some other parts in the GC CRD that can whine.The engine fan is hydralicaly driven off powersteering pump.Mine is being replaced under warranty due to a transmission like whine in side vehicle.also the auto trans fluid pump in auto makes a whine when on the way out
Check the rear CV on front tailshaft transfer case end, if the rubber boot is split or destroyed I bet the noise is comming from there. A ford BA one will fit, go to a mechanic that dose CV's to check it. I have some pic's here some where..

And then check your CV's before you start looking at diff kits. The front diff is pretty hardy and unless you have had a really bad pinion leak should be ok.
If at times it sounds like wind in the roof racks, as Clarky said check front drive shaft rear CV, just replaced mine. Check the rubber boot, hard to see. Did a post on it about 2 weeks ago. Drop shaft and take it to a CV specialist, a Hardy-Spicer CV-861 same as a BA-XR8 uses. Takes a morning to do.
