    Circlip is internal. Shaft just pulls off.

    No, you don't need to do any of this, they dont sieze at all, metal to metal is good, and they don't wear out


    Now back to reality
    Yes, leave it overnight and let the oil do its magic.. don't force it too much, keep soaking it.

    You may have fun getting the shaft back up.. if you do take off the bottom shock bolt and jack the shaft up a bit ... this will help

    I had this happen when my 2017 bike went in for a 6000 mile service last year at Bahnstormers, they could not get it detached and ended up fitting a complete new shaft drive under warranty. The bike had less than 6k had never been off road or under water, kept garaged , never jet washed and I had had no problems with it at all, still haven’t really.

    Just did my 2016 GSA - some rust but was completely dry though there was some of the waterproof grease on the bellows. Bit apprehensive doing the job as it was my first time but it was a doddle really.

    If you don't mind me asking what does the shaft need to come out for, is it on the service schedule or was there a technical problem ?

    Mine was the same (2016 bike) wont go into it too much because I already wrote chapter and verse on another thread and all the "experts" tell me I was having some kind of drug induced dream because this didnt ever happen to BMW bikes). However I pulled the whole shaft out attached the final drive like you because i couldn't split them - sacrificed the rubber boot that was in good condition so that I could get a cold chisel between the UJ head and the end of the spline - used Freeze spray that has a penetrating oil in it - supped a couple of cans before it gave any - but it was a real hard thing to separate. It was dry and rust welded all the way to the end. Once off I used a dremel and a mini wire brush to clean all the splines (Male and Female) and new rubber boot and plenty of moly grease and then the white Moly paste to seal the boot.

    Was a fair job but in the end sorted it - if it had been under warranty I would have been pushing for a new shaft and final drive but I only took the first year of the extended warranty.

    Not a service item via BMW dealer but I have decided to set this as a 12 month repetitive job so that it keeps it free and removable.

    Dont think it is too much of a detriment to the bike it not being done just means you have to pull the hole shaft out if you want to do anything like change a split rubber boot. (By the way mine originally was in perfect condition so the water ingress didnt come from there.)

    Anyway good luck with it.

    It is threads like this that shows that you should be sceptical with a fair bit of the information and advice you receive on sites like this.

    Sieve through the posts and pick out the ones written by those who seem to know what they're talking about. I.e.people who do their own work or see it first hand.

    If the rear drive ever needs replacement bearings or you needs re painting or fails and you want to replace it..... not having a rusted sized driveshafts makes life so much easier.

    If nothing goes wrong then happy days but as theses bikes age and increased mileage we will see more maintenance required to the rear drive.
