The rear wheel needs more attention, so it will take a little longer. Meanwhile, I took care of the final drive. I was surprised that, after loosening the four screws with which it is fixed to the swing arm, water flowed out from it (about half a glass). I disassembled it and looked inside the swing arm. Some splashes of water are visible, but no accumulation is visible. I cleaned it as best as I could and as far as the place next to the gimbal allowed. The rubber bellows from the cardan cross is not detached or cracked, I checked. For now, I have removed the entire final drive from swing arm (could not remove the ABS sensor, it is stuck in its place), cleaned, degreased, repainted, reassembled and greased, changed the oil inside.
