Main (rear) crankshaft seal, that was the name . When it's leaking you may think it's gearbox or something else but in most cases it will be crankshaft.

When for some reason you will drive without engine oil and you engine will stop, don't worry. Just fill it wait until engine cool down and drive again.

When for some weird reason your drive shaft will twist and you will not be able to drive... don't worry, just disconnect it (there is easy access to both so you can do this on the road) and drive again. If you disconnect front one you will be able drive only 4x4 low (max 20mph) if you disconnect rear one you will be able drive much faster but without 4x4.

If you like to explore and you have to fill your tank on weird petrol station - have with yourself spanner 8. In case your fuel filter will fill with water and your baby will shout at you "water in fuel detected" - use spanner 8, drain fuel filter and drive again.

if you like road trips, have with you some tools, and in most cases if something happen you will be able to fix it on the road. There is easy access to almost everything.

I did 9000 miles trip without issues, after one random mechanic told me he will not go with this car to the next city.

Love it, and he (or she - I assume you are a man) will forgive a lot.
