The diffs have been burnt, toasted, on fire at some time
The front crown wheel and pinion seem ok
The rear had the oil cooked and then moisture has entered, but it is not pitted so may clean up
That is if I can ever get the axles out or the front hubs apart
Life lesson, If you have a burnt vehicle > strip it while it is warm and chuck all the parts out in the rain
If you store it in a shed after a few years every bolt will be permentaly siezed and the metal continues to rust away
The parts from my mini that burnt, that I did not want, and threw out, are still OK, everthing in the shed simply disintergrated
All three of the gearboxes I have, have been full of water and will need serious attention
At first I was perplexed as to why anyone would cut the springs with an oxy, but after careful study, they were on the diffs, so toasted too
more to follow
