At the same time of replacing the front tire, I also needed to change the differential seal on the splined/wheel side. This was at about 54000 miles on a 2013. I found a video of somebody using a a drill bit and a sheetmetal screw to remove the old seal. That was easy-peasy to do. I cleaned all of the splined surfaces, re lubricated and installed with new gear oil.
I did have a weird thing happen. After the trip the bike sat for a couple of days before getting washed. Then it sat for several more days, until the replacement diff seal arrived. I turned the key on and got nothing. No fuel pump, no lights, nothing. I thought the battery was completely dead. Both my 50+ year old battery charger and multimeter died at the same time. Another delay. Once the battery was charged back up, I was not able to find any blown fuses or worn thru wires. The voltage hasn't dropped in the last day or 2 so I'm hoping that it was just a fluke. It could be that taking the fuses out and in along with unplugging and replugging several connections was the issue. I guess I'll find out.
