been driving fine with no dramas for the 6 months i've had the thing, then on the way down to sydney the other week i started to get a real howl out of the drivetrain somewhere. got it back from sydney on the weekend (wasn't driving in syd), howling in all gears under load. have since removed the rear tail-shaft and driven around FWD, no noises.
assuming rear diff is shot, has been suggested maybe pinion bearings? (could have confused two seperate things here...) what's "normal" to go on a standard WT rear diff? any easy fixes?
am still driving in FWD, this shouldn't cause excessive wear on anything should it?

I drove round in front wheel drive for a while in mine when I did a pinion bearing be careful with it as the pinion can be "pulled into" the carrier and under certain conditions can lock the rear diff, though this is unlikley.
Grab the pinion flange give it a "wobble" if you can feel movement .. it's stuffed basically ..

first off you need to know whats wrong ??
Is it the pionon bearing ?? if so you will need a new pinion bearing, seals and crush sleeve/pinion spacer .. and someone who knows how to put it all together ..
is it the diff bearings ?? they are pretty cheap about 15 to 20 a set from memory, but you will still need to set the gears back up once you change em.
Is it a chipped gear ? will make a bearing like noise, but only occasionally , as the chipped teeth mesh together..
If you can find one .. grab a second hand unit and bung it in .. then at your lesuire, fix up the one you have .. use it as a learning experiance.

Can the pinion bearing be changed from the front of the diff or do you have to pull the centre out??

You have to pull the centre to set the gears up again (as the pinion depth will most likley change, as you should be using a new crush sleeve\spacer as well)

Yes I had my air locker moved from the back to the front but i had to get new side gears for it to fit. I don't know what that means but that is the facts jack
Next week my little shelf will go in for a rwc I think
the rear diff has a 27 spline 1.09 inch (I think) axle the front is a 19 spline .9 inch axle .. (these are very rough numbers in inches, but I am pretty certain the spline count is correct)
So no a fron centre cannot be used "directly" in the rear, but by swapping the side gears your good to go (the side gears are interchangeable)

Place your bets here

stumped did this noise start before or after you fit the 4.16 gears ???? removing the rear tail shaft & driving front wheels only will reduce the load on the rear output shaft bearing in the transfer case. you did say the noise was under load . Your probably right with a diff or wheel bearing being the problem but bearing noises can deceive.

the noise was before we fitted the calmini's, so it's not the transfer.... got a mate who know's 'bout such things to look at it and he reckons diff, but wheel bearings is worth looking into too...
... although, if it was wheelbearings wouldn't the noise be constant? not just under load, and even without drive to the rear (like now)?
