Given I cannot find a Haynes-like manual for my late 2005 Defender 110 Double Cab XS does anyone have the low down on the servicing basics...
Nice truck. As it's an XS, does it have ABS/TC? Damned near my perfect Deffender that is.
Anyway, back to the question.
Difflock do some servicing kits which include all the parts for a full service.

You will need oil too and the Evolution range they sell is superb.
You will need...
R380 Gearbox: 2.7 litres Evolution One.
LT230 Transfer Gearbox: 2.3 litres Evolution Two.
Front Axle Differential: 1.7 litres Evolution Two.
Rear Axle Differential: 1.7 litres Evolution Two.
Swivel Housings (each side): 0.35 litres Evolution Two.
Wheel Bearings & Propshafts: Purge all old grease and refill with "One Shot" or Long Life Lithium Grease.
Oil Filter
Fuel Filter
Air Filter
Rotor Filter
Probably the only thing you will need to research is the change of the rotor filter as that is a bit weird if you have not encountered it before.
Also, I highly recommend you get a Difflock Drainplug...

Basically these replace the standard sump plug with a spring operated valve plug. You unscrew the cap and screw in an adapter with a hose attached. As you screw the adapter in, it pushes the valve open and the old engine oil starts to drain down the hose. It makes oil changes very quick, dead simple and mess-free.
