If you look at your trip, the longest distance that you will be travelling from major centre to major centre is around half of your trip say at 2000 klms
If your car is well serviced, then you should be OK for your trip - let your service company know that you will be doing a remote trip, and they will check most of the major things like wheel bearings, steering components, brakes, etc, etc. This should mostly eliminate the possibility that you will have a major component failure that will stop you in your tracks for a trip of 2000 klms.....
Looking at the major fails that seem to be common and can happen out in the middle of nowhere, and of which will stop you in your tracks, there are a few - but most relate to the bits that rotate the most.....
I carry a spare set of rear wheel studs and nuts ( the rears are longer than the fronts and can be used in the front if necessary - they will just push and break through the ends of the encapsulated nuts ), a belt and tensioner.
I carry the stretchy self adhesive silicon tape, which will bond to a hose, and to itself. This can then be used on any pipe / hose.
I carry an assorted selection of electrical connectors, wire, screws, small gauge fencing wire that I can easily wrap and twist up to hold things together ( like my broken roofrack in the middle of the Simpson ).
I have never had to use any of the major bits, and have carried the thin fencing wire around with me for nearly twenty years without using it...... until recently
Think about it as logically as you can, and try to take stuff that can be used for multiple repairs, and not just for one thing only ..... for example, I carry a portable gas powered soldering iron, and I was able to use this to repair a jeep that was with us, who had torn a hole in the automatic cooler lines to the radiator .... we removed them, made a fire and carefully heated up the pipe to make it easier to solder and to burn off any transmission fluid inside, and I soldered it up ... with a small fluid top up, he made it back to Melbourne from the middle of the Vic High Country ...
