Trasnfer case flange from my Gurkha
 

This is why I still regard German engineering to be the best, this is my flange which I removed for inspection, the seals had given up after 10 years so I decided to take it out for a thorough look. After 116000 miles of severe off road and hard pot holed ridden on road use, there is hardly any wear, the splines look as good as new. The flange is from PUCH VG32 transfer case used in my Gurkha. All the internals of the transfer case look brand new inside.
