I have had a knocking? grinding? shaking? sensation on acceleration for the last week or so and it is getting worse. I thought it was the rear drive, but I did the rack test and checked the rear drive fluid for flakes. Drive fluid and magnet completely clean. I put the bike on the center stand and ran the bike in second gear and could hear a knock at the drive shaft housing just in front of the rear drive unit. I could actually feel the knock at that point but nothing at the rear drive or further up the shaft housing.

Is there a way to check the drive shaft without complete removal of the rear drive to know for sure what the problem is? I downloaded the instructions for removal of the rear drive after I did the search, but I don't want to do his unless I know for sure what the problem really is. If it is the drive shaft, I would like to have a replacement on hand before I start any work to fix it.

Thanks

It sounds like a u-joint in the drive shaft. Which will mean replacing the entire drive shaft. The rear drive is relatively easy to remove.

I have reviewed the instructions for the clutch slave drilling and it covers the removal of the drive shaft - to a point. My question is: must the entire swing arm assembly be removed to replace the drive shaft?

Is there a way to inspect the drive shaft prior to removal to make sure that the drive shaft universal joint is the problem?

Thanks for the reply.

When you remove the rear drive you get the rear U-joint with it. It is awful hard to pop the rest of the shaft loose from the tranny without pulling the swing arm loose. I pry the end free though the swing arm mount hole.
