At a little over 8k miles I thought it time to lube the splines on the 3R. I'm one of the few who went through a final drive and drive shaft on the older models and have tried since then to do this with every rear tire change or, at least, every other, so every 4 -8,000 miles. Although there was a thin coating on the splines, it looked like it was about time to add some moly. I also change the final drive fluid with each tire change- it's cheap and easy.
The process was pretty straightforward- see pages 1256 - 1264 in the manual. Basically, remove the wheel, rear caliper, disconnect the ABS sensor and the wiring for the license plate, and the four nuts to the bevel box- lube and reassemble.
Here's what it looked like.....
