    Not sure what the Yokes are, can you enlighten me ? I marked the housing and cover before removal as per instructions in Clymer manual.

    Thanks

    Last month, on a trip to Creel, Mexico, I noticed this...

    [​IMG]

    And also got this... and no ABS for me :eek1

    [​IMG]

    So I decided to cut my trip short and leave the Devil's Backbone, Mazatlán, Puerto Vallarta and Guadalajara for the next trip. Headed back to Houston, Tx., my base town. Some 100 miles from Houston I noticed a mulching sound, like someting was being chewed up inside the FD...

    I made it to BMW of North Houston

    [​IMG]

    Sure enough, the FD was gone, and when it overheated it toasted the ABS sensor too (that's why I got the "brake failure" light). They told me I had been very lucky I made it back.

    FD oil splashed all over...

    I've seen some discussion about a new service bulletin on FD maintenance. Last one I heard about was that the FD fluid should be changed at the 600 mile service, but I've seen mention here of a new bulletin to service the FD every 12k miles, which puts the new "Lifetime oil" FD in with the same schedule the my old 1150GS had for final drive service (although it was a hell of a lot easier on the 1150 with a bottom drain bolt).

    So now are we really up to BMW scheduling 12k FD services on the 12GS? I want to make sure I'm keeping in warranty (Although, that's pretty hard when you can't get any info from BMW). Yes, I've checked with my local dealer, but they only have the 600 mile change bulletin at this point. Of course, advrider.com knew about the 600 mile service bulletin a month before my dealer got that info.

    Thx

    Ed,
    I could be way wrong here, but wasn't the 1150: 6 oil, 12 tranny, 24 final drive?
    I usually did them altogether at 6 and could've forgotten 'the manual'.

    Hey, You are right. 6 oil, 12 trans, 24 final, on the 1150GS. I just got used to doing the tranny and FD every 12k as it was so easy to do.

    The truth, yes.

    An xyz thruster and o-ring on your shuttle isn't a big deal when you're in Cocoa or Houston, but get way out there...and it's a whole nother ball game.

    I guess you did'nt take the whole drive unit off yet. but if you did there is a ujoint on each end of the driveshaft with a slipjoint at the rear where you would take the drive unit off the swing arm. When you put that slip joint back together the ends should match up like in this expertly drawn illustration.

    Better drawn than some of the things I see from our CAD system at work:D .

    I'm going to let a BMW tech guy ride the bike on Saturday to tell me if the vibes are normal and I'm just being paranoid before I dig into it any further. But if I have to I'll look out for the alignment thanks.

    I've got 27,800 miles on my '05 12GS and so far all's well. My warranty is up in August of 2007. Knock on wood....

    I have a friend whose 12GSA's final drive failed at just over 30,000 miles. In Chile.

    Is there anything one can do to prevent the problem.?

    Take it to the dealer and ask for a pre-emptive rebuild, bearings, seals etc.? It should be cheaper than a repair and at least you can decide on the timing.

    Or change oils, would fancy additives or some such help.?

    I gave the drive failure issue scant notice untill I added the responses together.:eek1

    Well, I get to add to this thread. :cry

    Fracked crown gear on a 1100GS. The final drive was rebuilt 30k miles ago.

    Didn't notice a damned thing until pieces that looked gearlike started coming out of my final drive amongst the oil.

    That failed bearing and seal looks mighty nice compared to mine.

    Except that the VFR had its share of problems, too. If you don't recall, in the 80's their cams would eat themselves up. IIRC, it was a lubrication problem. The thing was, Honda admited it and they and the aftermarket fixed it. And I used to own one; it wasn't the greatest, though it was good.

    This thread (most of the 12 pages, anyway) reminds me of a Macintosh ad poking fun at MS Vista's security:

    Security guy: You are pointing out Vista's flaws. Cancel or allow.

    PC: Allow. I could turn him off but then he wouldn't give me any warning at all, and that would defeat the purpose.

    Security guy: You are coming to a sad realization. Cancel or allow.

    PC: Allow...

    I have been lurking on this site for some time practising the necessary due dilligence and research involved with purchasing a new (at least to me) motorcycle. Of all the issues that I have read about (whether real problems or just opinions) the FD concerns me the most.

    After reading this whole thread and sifting through all the fluff, general bitchyness, opinions and real information, I have come up with these points as a summary:

    - the FD problem is a real issue and not imagined or experienced by only the vocal minority.

    - (counterpoint to previous) BMW has sold many, many bikes with a shaft drive, there are many owners of said bikes on this web site, but there are only a handful of these people who have experienced problems and have shared with the rest of the readers.

    - The problem (assuming there is one) lies not with the bearings, oil type or maintenance regimen, but rather with engineering, whether bearing type or size, or with the single sided swingarm.

    - Time between failure is unknown. There is no acknowlegement from the factory and no known suggested bearing replacement schedule other than a MTBF of somewhere between 15000 mi to 40000 mi.

    - On 11xx cycles, one can perform periodic bearing replacement to reduce the occurance of this problem. This is not possible with a 1200.

    - BMW has redesigned the FD on 1200s to eliminate this problem and are essentially a sealed unit with no user serviceable parts. This may or may not have cured the problem. There are far fewer of these owners who have complained of any issues on this site, but it is a new design and fewer have any significant mileage, yet.

    - Regardless of the model (although I expect all 1200s are still on warranty), if one is not capable of performing the repair himself or experiences the problem in a remote area, the fix will be rather pricy.

    If my summary is incorrect, please enlighten me.

    I am/was in the market for an 1150 or 1200, but am not so sure, now. Is BMW reliability a myth? Is that legendary teutonic toughness a fiction, or perhaps they have lessened themselves to the same level of some other builders: its good until the warranty runs out. Yes, I know that regular maintenance is paramount, but how do you prevent a possibly sudden problem (other than with luck), that may or may not occur, and is not even acknowledged by BMW? In my opinion, this head in the sand thing is crap. Lets find a solution or a possible work around.

    Well, you can only vote once - I would've voted twice, if the option was available, to make the numbers accurate...

    When mine failed at 35k miles, BMW NA initially denied warranty claiming the bearing replacement is a maintenance item. There was some ambiguity, but my take is that the BMW said the issue wouldn't have occurred had I replaced the bearing at 24k miles.

    OTOH, many have failed short of 24k miles.

    Overall, FD failure rate is, IMO, higher than it should be, but also not that common given how many BMW's there are running around.

    My FD failed on my '02 1150GS at 41K. Naturally, the warranty was gone so I went to the dealer prepared to fight about having them fix it since it was so close to the end of the warranty period. They replaced it, not questions asked and no cost to me. I now have 61K on the bike (an additional 21K on the new FD) and have had no problems. When my original failed, it just went out without any warning, on the freeway and left me stranded. (not bad though...it was in San Francisco) I have always performed the regular maintenance and it still went out without pre-warning..I voted already..but would vote again too in order to get the #s up. :lol3

    I'd like them to produce the service schedule that details this replacement. Sounds like bollocks to me...

    The results of such a survey are useless for drawing inferences to the universe of BMWs. The sample here is self-selecting, and that's ok as long as everyone understands it has no correlation to all BMW bikes built.

    I challenged the denial of warranty. I said if BMW NA or the dealer could show me ONE published entry saying that the bearing should be replaced at 24k miles, I'd withdraw my warranty claim.

    BMW NA either couldn't or just blew me off. We were at loggerheads until Rob Lentini intervened on my behalf which got lots of action from BMW. Until then, it was like shouting down a well.
