Ludicrously long winded process taking over three months and involving transfers between land rover dealerships that never arrived needing me to track down my car and transport it myself, lawyers, ombudsman's and a fair bit of stress. But in short and predictably but also bizarrely this ended up being the rear Diff. 
Somehow almost all the bolts that attach the crown wheel had sheered off. I genuinely have no idea how this happened, again I'm a city person that drives too and from work. This must have taken a huge amount of force given the sheering strain of bolts. Even more bizarrely the axles are fine both sides, I would have thought they would have failed through strain before the bolts attaching the crown wheel sheer. 
The "Spud shaft" that land roved pulled out ( assured me was the cause as it's splines had sheered off and then replaced) in fact looks pristine with zero ear and tear as I have it in my garage. 
The transfer case was fine. 
Land Rover were in some ways atrocious and disorganised and in other ways they were ok. After arguing with Land Rover Australia that I had land rover road side assistance as per the servicing agreement they towed the vehicle and got me a hire car. Initially they offered 40% of the repair cost for the spud shaft, ~2-3k repair bill all up. Then when it looked like it was going to be the transfer case and diff extravaganza at over 20K repair bill there was radio silence with it always being with the "Warranty assessors". So I then had to talk constantly with the land rover dealership who were repairing it, they eventually and understandably got fed up with not being paid and refused to do any further diagnosis. At the same time I realised I had Extended Warranty insurance, in parallel I pursued this. This insurance is utter junk, they refused to pay for the tow truck or hire car until the repair was approved, they refused to approve the repair until the cause was diagnosed, they refused to pay for any diagnostic fee to identify the cause, and they refused to take the Mechanics report as a diagnosis they wanted photographic evidence. In short this is not a warranty extension it is a pay money and receive diddly squat. This Stayed like this for 2 months with Land rover paying the Hire car the entire time. I consulted Lawyer who said i had a very good case under the ACCC laws and should pursue it against Land Rover and that I also had a good claim against the insurance company (But they would say that as they want the case i guess)and should pursue that but should try the ombudsman first. I took the Insurance company to the Ombudsman, Literally two days after I lodged the claim with the ombudsman I has the insurance company and their Underwriters write to me saying they would sort the claim and then the national claim manager rang me to say they would approve it in full. 
The Land Rover was transferred to the Hobart dealership at which point it was "lost in transit" for a couple weeks. It ended up being at a Depot. Land Rover assured me it was safe to drive so I then had to pick it up from a depot and drive it myself to the Land Rover dealership. From there Land rover cancelled my hire car. It then took another month or so to get the diagnosis and repair completed and all costs were covered by the insurance company. 
TLDR, Dodgy Landy diff and Dodgy Land Rover Australia.
