Driveshaft technical question

[Rhubarbray]

Ok, question for some of you who may have a spare driveshaft so you can take a look. I was looking at spare parts on our favorite auction site when I noticed something strange. In the first link the seller claims "unusual wear" on the rear splines.

Something from the spline rolling operation?

An interesting question back to you :

Are you experiencing probs with yours? If yes, maybe explain or point to a thread you've got discussing this (?)

This seems to be normal. Have a look at this thread...

Its hard to tell but there looks like there is a worn step in the splines. The ends are made that way but there appears to be a worn step the length of the spline. The picture may be deceiving. I see it in posts 1 &3 but do not see a step in post 18.

Nope, all good. But I do have a habit of stocking up on common wear parts for my bike. I'm considering them an insurance policy, I'd rather have them and not need them than need them and not have them. And for $20-40 that's a cheap insurance policy.

And I've been on here long enough to know better than re-ignite another Moly thread!!

I have never heard of a driveshaft going bad, now a U-joint will go bad. My ST 1300 has over 260,000 miles and only one U-joint replacement and the original driveshaft.

Agreed. My memory is pretty well shot these days, but I can't ever recall anyone having a major driveshaft issue. If anything it's the final drive gear set (ring and pinion) and / or the associated radial bearings that folks question.
