I removed my worn out u-joint without removing the swing arm.
It's at the back of the driveshaft, near the "pumpkin," where the second set of splines is.Wow that thing is shot. The oil seal you are talking about replacing is at the output shaft?
I wanted to replace the rubber boot and see if there was any other damage. I think that the boot may have come loose or otherwise let water into the u-joint, as the u-joint and front splines on the driveshaft were dry as a bone. I also wanted to replace the swingarm bearings.I removed my worn out u-joint without removing the swing arm.
