Diff recall was not done on all cars and there are plenty out there that have not been done....
As for the gearbox, anything past 90K on a Diesel is on borrowed time, and on the V8's is a time for diligence.
You say you have experience of 'AWD' vehicles, well lets put it this way - they are not Range Rovers.
The Range Rover is a pure Diva....the Prima Donna of Luxury 4x4's
They come with expensive running costs and even more expensive repair bills.
They are unreliable, they are of poor build quality and they will empty your bank balance (even a healthy one) rapidly when they go wrong.
The permanent 4 wheel drive system through the Torsen B Torque Sensing Centre Diff and NV225 Transfer box is reliable (the shift motor switch pack fails mind you) so with regards the drive train (bar the front diff, and grumbling rear propshaft bearings) they are good.
The M62 VANOS Engine is strong and bullet proof aslong as servicing is up to scratch although they do eat PCV hoses and valves....the Cooling system requires regular maintenance and the Radiators spring leaks...expansion bottles crack on the underside and the hoses split at the plastic connections.
The water pumps fail and the Electronically controlled Thermostats fail causing a Thermostat MAP fault in the ECU. That's bearing in mind the coolant leak hasn't seeped up the wiring loom corroding the wiring with it.
The ABS Short Harness gets water ingress corroding the ABS ECU pins. ABS Wheel sensors on the front chaff through the wiring as they rub on the rims.
Front Air Struts have a 7-8 year life span, and the rears slightly less.
Air Compressors wear out when the struts get worn requiring replacement or if your lucky a rebuild.
EAS Valve Block is made of brittle plastic and can fail over time.
Rear Suspension bushes wear out with grave regularity and the fronts start to grumble after 60k miles requiring replacement.
Rear boot corner leaks on the very expansive DSP amp and other electronic modules in there inc. the Sat Nav and TV Module.
Fuel pumps go south commonly too.
Couple all this with Weak Gearboxes, niggly electrical issues and a tendancy for the batteries to go flat makes the L322 a fantastic car to own
