Just spent a few hrs checking & servicing the old girl.
Just thought I would post my recommendations for a post trip check etc. In particular the gtg in the Vic high country & rivers.
In no particular order or priority:
Change rear diff oil. The rear LSD does a lot of work on those hills & also then gets a fair dunk in the rivers. Especially if you don't have breathers.
I don't have aftermarket breathers, & after all the reccies & trip there was still no water in any of my fluids. However the rear diff oil looked well used, this is standard.
This is what I use in Prado rear diffs
Check auto trans for water. If I had an auto after all that hill climbing & risk of water getting in I would change the auto fluid.
I changed my gearbox oil & transfer case oil. Gearbox oil was used & transfer case oil similar to new, this is standard.
This is what I use in Prado gearboxes.
It is recommended to lubricate your propeller shafts after water crossings. You have done a lot of water crossings.
There are 3 grease nipples on each shaft.
Check your tyres for severe damage. On tracks like billy goats its possible for them to get very cut up.
Check your fuel tanks for damage.
Visual check all nuts & bolts. Check Bullbar mounting bolts with a spanner. Check bottom of front strut nut, with vehicle on floor 19mm should be very tight. Check top of rear shock nut if no nylock is fitted.
Usual under bonnet fluid level checks. Check & clean air filter.
I will come back & edit as I remember things I forgot.
