So my 90 won’t move, it started with a weird noise coming from the front driver side wheel I managed to limp it back home, turned it off and on again as any good British person would do. As it starts up again I select 1st gear to see if it pulls off it did for a short time and then stopped. Now whenever I select a gear it won’t budge but when I have it in high diff lock it will move and that’s the only way to move it. Reverse won’t work either. Front prop spins freely. Anyone any thoughts please?
