I finally got round to changing the oil in the rear diff this weekend. The 'old' oil looked great - like a stream of clear honey.
Whilst I was at it I thought I would take a peek at the oil in the front diff. I did the Birfield repack and changed the hub oil seal and diff oil in January, so was expecting the oil to be clean. Unfortunately, as soon as I undid the diff filler nut oil started to come out. That's a bad sign since I know I only filled it up level with the hole. If there's more oil in the diff than I put there then it has come from somewhere - moly grease?!
After looking carefully at the oil it was apparent that there was moly grease mixed in. You can imagine how happy I am at the prospect of having to replace the hub oil seals again. I can't think what I could have done wrong last time. Any ideas / suggestions?
Cheers, Jim
