My defender 110 has an embarrassing problem, he’s leaking some oil from his rear half shaft at the wheel. It is coming out of the dust cap. Not a lot of oil but started when traveling the rough gravel F roads of Iceland. I could top up diff or get it repaired (prob not cheap in Iceland). Any suggestions what to do (we are away for another 2 months and expect to drive another 4-5k km before getting back to Ireland). Anybody know of a cheap Land Rover Indy in Iceland?
