I'm scratching my head. March 2010 I grenaded the Planetary and Transfer gear in my '07 XF 1000 sp. All of a sudden there was a loud "Crunch" and no forward motion. Being 4 miles from nowhere we took off the belt and towed it to a nearby road to get loaded. I am sure that is where I lost most of the teeth. It was the worst sound ever during that tow. Replaced the Planetary and Transfer gear, all the bearings and seals. About a kg. of metal came out of the case. Topped it off with 12 oz. of ACT fluid.
350 miles later I dopped the oil and found filings in the oil. Out came the DD and pulled it apart. Every thing looked good, bearings all good until I pulled the Planetary. One of the 5 little gears in there blew out the brass shim and was grinding away at the structre of the gear set. Not only that, but there is a discoloration one the metal of the Planetary, Xfer gear, Slider, and output assembly. It looks as if there was boiling hot oil poured through it and it ran down it. It looks like all the discoloration would line up. There was exactly 10 oz. drained from the gear box, and I was told there could be up to an oz left insideclinging to the gears and case. If so that would give me 11 oz of fluid. No sign of where the oil went. And even so would 2 oz missing cause one of the ten gears to fail after only 350 miles.
The DD was completely cleaned out when disassembled with brake clean.
