Some photos off my phone of his progress since he hasn't updated the thread
Pre January 2018...
After the August camping and before our January trip most recently, rear pinion seal was replaced
And the coolant needed changing (brown rusty looking water)
Thought that might flush the heater core and fix the almost no heat issue but no it did not
Then major play in rear prop shaft, pulled that and tried to swap in a known OK used spare off the yellow 110...
One cup missing all needle rollers. Nice. Another cup chipped, whole shaft really needed to go. See fragments of broken needle rollers in adjacent cups...
In the end what we did not know is that early land rover 90 models have earlier SIII sized u-joints fitted in otherwise similar prop shafts to later ninety/oneten and defenders. So when we put an old spare off a later shaft it was not the right size and had enormous play, ended up getting a new shaft from RN that arrived later, rear shaft now matches later defender specification
Loaded the car on a trailer a week before the trip and sent it down to the desert to wait...
