    I just figure I will drop the drive each oil change time since I have to change the FD oil then too anyway.

    Is the spline lube included in any of the standard services for the GSW? I typically let my dealer handle the scheduled maintenance so I'm wondering if this is something that they would take care of or if it's something I should do on my own. I just had my 48k service completed so if it's something that's not included with any of the services, I'll probably give it a go myself when I get some time.

    I put a rubber plug in the speed sensor hole so not to lose any oil.

    Here is another "Thanks and Well Done".

    Can we chip in to buy you some metric sockets?

    No, they will not have it in the books. If you let the dealer do all your work you will not get a spline lube.

    Why not just do it when you change the FD oil? Seems the logical thing to do. Besides, it is 180ml of oil. Not about to break the bank if you just change it.

    Thanks! Sounds like I should probably dig into it myself. I ride in the rain and do plenty of water crossings.

    In that case I would suggest you at least do one. At those miles, if you are clean in there, you can skip doing it again for 12-18K miles.

    What do I do if it isn't clean in there? Do I need to replace parts or can I just lube it and hope for the best?

    It depends on what is going on. The usual issue is rust from water sitting in the area. Clean it up well, and use a corrosion inhibiter. This is important, check the U-joints to see if they are loose or binding, or show signs of rust around the rubber seals. Clean and protect them with a rust coating that is friendly to the rubber seals on the U-joints.

    If you have oil sitting in there, look up the swingarm tube to see if the oil is coming from the transmission. If no oil trail down the swingarm tube it is likely a leak on the FS input shaft. Tiny amounts of oil are usually not a big deal, but you should watch your fluid levels and watch the final drive boot for signs of leaks.

    99% of the time everything is good and you just clean and lube the splines and put it back together.

    Can I change the FD oil without opening up the boot and flipping the FD back?

    Sure, remove the filler and then the drain. The fluid drops straight out. Put the plug back and fill the install the filler plug.

    Thanks!

    I plan on changing the FD oil each oil change. Why not, right?

    I change mine at every service since I cross streams now and then. So far always comes out clear--no water. My odometer is somewhere north of 24K miles. That pricey bottle of BMW gear oil lasts a long time at 180 ml per change.
