Drive shaft splines.

I've been the proud owner of multiple GS motorcycles since 2000. Theres not much I don't know about the bikes.
What i do know is there seems to be a lack of posts on here and other forums that show failed shaft splines. None. Nada.
Plenty of final drives on earlier 1200's. But still no shafts.
Hope that helps.
Or. If you can point me in the right direction for all these elusive post , much obliged!
 
Do you consider driveshafts that are stuck fast on the splines of the drive pinion and do not therefore slide on them (all be it only slightly) as the rear wheel moves to comply with the road surface, as a failure?

What we only see is a percentage of people who have problems

the people who dont have problems, funny enough dont post.
 
you are missing something

If you need to service or exchange the rear drive and you have the shaft effectively welded in, the job becomes so much more hassle. As the bikes age you will need to change and service bearings.

For the sake of a bit of grease and time, why would u not?
 
I think the point we should all be concerned about is. These bikes are expensive and under no circumstances should they leave the factory without being greased. Sending these photographs to BMW Uk and HQ in Germany would do no harm.
I have owned 7 of these fantastic bikes but that doesn’t mean I would except poor workmanship.

You didn’t answer my question
 
Ah, we got there in the end. There is the issue, you have your thoughts on what constitutes failure, and others have theirs. Never the twain shall meet. Differing opinions on a motorbike forum, how novel.
 
It's part of the suspension function for the final drive to slide on the splines.Thats what they are there for.If they seize, suspension function is compromised.Why not just lube them? Can't understand why you wouldn't do it...
 
I don't know enough to comment either way, but I'll ask a question. Does the shaft slide in and out of the female portion in normal operation?
 
Fail ?. When nothing at all happens? Dear oh dear.
��

When a major component fails to operate as the manafacturer designed it, because there is a design fault, there is definately a fail along the line somewhere.
Fail does not have to mean mechanical breakage.
If you knew that your bikes FD splines had rusted together would you fix it?
