Olgry 1,
I think I found a clip on both ends. Slight movement very free to a stop on rear joint. The length change with suspension movement is all in the centre spline part of shaft. A cardan should not move at the outer u/joint halfs. IMHO BMW have found that the final drive u/joint has been sliding at the driven end and have fitted spring circlip to stop this. I did find about 1/8" of movement there but 1" plus on the centre spline section. Both were well lubed. Spray can of white Lithium grease all round so when the carrier evaporates a nice film of grease is left on everthing.
Glad to hear you have fixed your bike, but have a look in after another 10000 miles, I know I will.
