Decided to do the splines when the new tire goes on. Still not to sure how many to miles to expect out of the avon
I've never been a fan of them, but lots of folks here do love them. I have favorite tires, but they all get about the same mileage. The favs wear more evenly and, of course, to me anyway seem to perform better.
 
Pretty dirty. 8k miles. If I can find a little plug of open cell foam ..

For anyone doing this do both ends. I got my grease this morning so I dropped my wheel and new metzeler to my tyre guy. As luck would have it all 4 diff studs came out. The flange looked pretty clean but I could see a few if the splines were shiny and not much grease to be seen.
I decided to look at the other end and there was nothing there. Slightly rusty and some polished splines again.

Don't short cut do both i

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.....
