I spoke to Quaife (Adrian) and he confirmed the unit functions perfectly well with the CDL, you just now have a ATB Helical LSD centre in place of an open centre diff. Its a drop in replacement with no loss of function.
I ordered one and will have it in a week.

Excuse my ignorance but why would a ATB TC diff centre be of benefit other than in high speed Dakar type racing where the racing takes drivers over varying surfaces and time is of the essence to avoid changing out of CDL to open diff?
I have no desire to criticise your purchase decision and do not invite a reprisal. It just doesn't make sense based on its design intention and typical application.

1. It takes care of the thrust washer/side gear issue.Quote:

A few blokes with a lot of grunt have reported the front end twisting up and lighting up the inside front tyre in off the line and turn situations.
An ATB centre diff would alleviate that too.
Audi have used Torsen centre diffs for years in their road cars.
Hmmm, could do with one in the LT95, actually....:(

No worries mate, happy to shed some light on why I thought it would be a good option for my 130.Quote:

I picked the Quaife unit primarily due to the reliability of the unit, both in strength and longevity. The fact it has an LSD function is just a plus when I driving on gravel.....the truck should will be more predictable on the loose stuff. That said for an ex-rally driver I poke along like Mr MaGoo nowadays!
Actually you mentioned changing to and from CDL and time savings engaging /disengaging it, its just of quality of life thing. Travelling most country roads off the main thoroughfares and you constantly switch from tar to gravel every time you pass a decently sized homestead. Again, not a reason for me to purchase, but an upshot.
An OEM replacement was $900 plus another $100 to upgrade the cross pin, $1000 for the same unit I have that was unrepairable at 154,000km. The Quaife unit is $1300 landed, considering the massive gap in engineering quality, longevity and strength, it was a no brainer for me. Like most of us I like to get into some remote places and have to have the truck as reliable as I can. The Minister For Home Affairs and I have been kicking around doing Singapore to London in this truck (she's a pom) and I base most of my decisions around the possibility I might just drag this truck into a container one day soon.
And this, the TD5 is chipped etc and makes good power in a heavy truck. The TD5 will be pulled at some point and something making more power, with no electrics, will replace it.Quote:

Update
I received the Quaife unit and it is a flash looking bit of kit. For all its good looks I have a few challenges with the installation as when fitted up I have a fair chunk of float to contend with.

With 34 thou float I have to double up on the bearing spacers (2.05mm and a 2.45mm) and shim the front output housing (1mm) to get the correct pre-load. It is a bit of a phaff around and another week spent waiting for parts to come from the UK. I ran just about everyone, including LR in Australia trying to get shims and no-one could supply the combination I needed.
I spoke to Quaife and I received advice that although not common, they have had a few customers say that float was quite large and exceeded the thickest spacer offered for the housing bearing.
Anyway its is all going together slowly...here are a couple of pics of a 'special tool' knocked up which might be helpful to someone doing a 230 t/case reco.
