Hi, Ive had my Fourtrack about 4 months and I absolutely love it. However, I was towing a horse trailer on wednesday morning when I heard a huge bang. I stopped immediately and checked everything but couldn't find any evidence of where the noise had come form. I have subsequently noticed I am losing a lot of oil and I think its from the transfer box. I haven't noticed any difference in performance whilst driving. Has anybody any ideas to what could have happened.

I also have problems selecting second when going down the box but I am reasonably happy that this is the much discussed mainshaft nut problem.
