To mount breathers to the transmission and transfer case, it's major. Removing the tailshaft to then remove the transfer case. My transfer case front seal requires replacing a slow leak (under warranty), actually in a fortnight. Yes I have a July 2023 build. Must drive 900 kms to get it done as it's the closest accredited dealer mechanic.
I am told to get to the gearbox, you disassemble the shifter, remove all those covers maybe one seat to get to it. Yes it's major.
Yep, more trouble than it's worth.
