Hello, i'm from Russia, sorry for my english.
I have Daihatsu YRV from Japan with 4wd, but rear wheels not real "drive". In fact car with only forward wheel drive.
Anyone try to repair "Clutch assembly, transfer rear drive", point 103 at this image http://eimg1.partsfan.com/img/daihatsu/jp/illust/B1/256110/8073a0ed961d4809a88673315a56f8e2.png
