 |

While cleaning my K11 after a 3000 mile road trip to Canada I noticed that the rear wheel had a very slight drag in a few spots while turning it during the bike wash. I didn't think too much of it and put the bike away. It was in the back of my mind the next few days as I pondered as to what it could be. Rear disc brake warp matched the slight drag but no brake rub noise was noticed.
I was checking out some posts in Tech on the board when I read Steve's post on his u-joint failure. Somewhere he mentioned as an afterthought that he noticed something similar to what I experienced. So I put it on the list as a possibility. I was not that concerned as about 15K ago I replaced the clutch. The u-joints checked good at the time. I almost took the bike out for a 300 mile run. I''m glad I didn't!!
What I found was very surprising and somewhat shocking as the trip to Canada was a quick up and back with many high speed miles on the super slab and some in the dark.
A big thanks to Steve (skdonlan) for mentioning it. It saved me from a road breakdown and maybe a serious crash.
Now I need to find a replacement shaft. I would have been so easy to manufacture these so the u-joint could be replaced.
Signs of excessive heat. This must have been red hot!
Cracked roller bearing housing, exposed roller bearings.
How many more mile before failure?

Mark - good catch! I don't think you'd have gone many more miles on that one.
Although Steve's experience was unfortunate, it's cool that his post was helpful to you.

Hey Mark, I'm glad you caught that, I got your PM.
I was lucky and RAL88 linked me to a used on E-bay that was only $60.
Check your rubber boots while everything is apart, replace them if they are dried out and crusty like mine were.
Good luck!

Hi, Steve,
Just as long as you are talking about the rubber boots and not about your riding companions when your incident occurred!!!

Right at 50K on mine, I've been told that's a bit pre-mature. I attribute it to a PO who was I believe a bit hard on the bike. Or possibly the dealer who did a spline lube (at 41K) and might not have properly phased the U-joints upon re-assembly, although that's purely speculative on my part.
My early warning sign, that I completely missed, was that when the bike was the center stand and I rotated the rear wheel, I could hear a slight clunk, clunk as the wheel rotated. It was a soft sound, so I just thought it was a normal sound of the U-joints rotatng. It wasn't unitl I got the new one on that I realized it's makes no sound at all when rotating.

Some of my riding companions are a bit old and crusty, but I'll keep 'em, I think they've got a few more miles on them!
