    Unless it is out of warranty.

    Then again, if the driveshaft fails you will need a new final drive too. Plus the rust is likely invading the U-joints so they will fail early too.

    Nope, the drive shaft and U-joints looked brand new. No hint of rust or any wear. Very clean inside there except for the splines themselves. The front splines had grease and were fine.

    I am not saying not to lube those splines, they were designed to slide so should. I know some of the pictures posted in this thread look pretty bad but mine didn't look like that. So because of having seen those in the future I will check mine regularly.

    So, revisited a year or so later, the splines are much drier than I would have imagined. Almost as if all of the vehicle in the moly paste has dried out.

    I believe this will continue to be a yearly MX item.

    What did you use? That doesn’t look like a molly grease that is recommended. Anything in a pinch but grease will not dry out and will stay put more

    especially considering how they looked first time around. Still, I’ll feel better doing this yearly.

    Is it too early to check the splines at 2000 km ? No off road yet, no riding in rain, and washed the bike two times so far.

    I was thinking to check and relube in spring next year, but I could do it until the winter starts also.

    if you've got the time, skills, grease, (final drive oil?) why not

    some years (17-19?) seem more susceptible to low grease issues than others

    presumably your bike is very, very new?, if so it's likely 90?% unnecessary to check now

    but if your bike isn't very new but only has 2,000km it would be very wise to have a look see

    ymmv

    My GSA is 2 weeks old. I will not change the final drive oil as it was changed at 1000km (600 miles) service, I will plug the speed sensor hole.

    imho?

    pulling apart a 2 week old bike that is still under warranty is just asking for trouble

    by all means have a look a month? before the warranty expires

    I though the purpose of this job is to avoid the rust and seizure of the splines to the final drive. I read about cases where rust was present after 4-5k miles.

    I also have 5 years of warranty, I don't think I am willing to wait that long :)

    My 1200 gsa was really rusted up at 12months. I lube all my final drives early since finding that back in 2016 as precautionary maintenance.

    I recently bought a 2018 GSA with 6k miles on it. I will be dropping the final drive over the winter just as a precaution

    I’d lube the splines no later than the 6k service.

    Certainly won't hurt anything to drop the FD and check the splines.

    When you do, take pics and post them here. It will be interesting to see how much lube the factory is using on new FD's.

    I don't see why wait for spring time if you can do it now - ymmv...

    So, I did mine, and to be honest not much lube on the splines... 2021 GS Adv, 2500 km, 3 week old bike.

    20211005_153624.jpg

    What I noticed, is a little tear in the rubber boot along with black rubber pieces/scrapes inside the boot. I might have caused the tear, I tried for a bit to pull the entire boot out in order to clean it properly, but I gave up at some point. Thing is, the area is thinner than the rest of the boot, when pinched between fingers, so not entirely sure it was my fault. Anyone seen something similar before?

    I put some staburags inside the boot along the tear hoping to seal somewhat the gap, but I guess I have to change the boot...

    Very dry in there, you'll be glad you did this now. And yes, sadly, you should replace that boot.
