Guide - If you don't know that it will fail - don't take it.
You need to find out what items fail frequently that will stop you from going on .. and you'll need to find out how to replace them ..
Might be better in the 4WD forum .. but I'd be looking for a group specalising in teh same model of landcruiser you have .. do a google .. and ask there .. could be a news group..
Things like radiator hoses and fan belts can have 'universal' fixes check your loacal auto parts place..
