    Place a spot on the poll for, "It hasn't happened yet but it's in the back of my mind". I can then join in the non-fun. BTW, I prefer Vital Signs off the album.

    57K miles no rear drive problems. Biggest problem (besides $$$$$servicing and low mileage warranty) has been a relay that didn't leave me stranded.

    If you do any creek crossings, always check for water in the final drive, and keep a bottle of gear oil with you.

    I rode bike for about 1500 miles on a rough crown bearing. After disassembly, I found one pitted ball and a pitted race. The seals and gears were in such good shape (@42,000 mi) that the only thing I replaced was the bearing (about $110). Total time for replacement: about 3 hours. Those are FD failures we can handle!

    I'm always on the lookout for the roughness. No problems yet in ~56k miles.

    Input shaft seal leakage at 30k. Just noticed oil in the swingarm at the rear boot. Upon further inspection, the pinion bearing was going south. Swapped drives.

    My other oilhead has 47k on it, and the rear drive is going strong.

    71K on my old RS with no problems.


    The PO of my GS replaced the FD prior to my purchase, but I have no details.

    Mine was replaced at about 5000 miles. An SUV plowing into the back of it might have had something to do with that, though :D

    No problems whatsoever after 15000 miles on the second one.

    Noticed a resonant 'thrumming' throught the handlebars for a couple of hundred miles. This disappeared and then I started getting weird feelings from the rear wheel (not unlike a puncture). Eventually, some 30 miles later (I was in the middle of nowhere and had to reach civilisation) the rear wheel started moving laterally - locking momentarily on occasion (I was doing <10mph by now). I eventually reached a town , put the bike on the side stand and...

    Took the wheel off back at Jorge's place to find...

    The wheel had moved about sufficiently to gouge metal out of the rear disc and caliper carrier (hence the intermittent lock-ups).

    In emergencies/ long trips, You can fix this problem by the side of the road -

    Take a spare bearing and seal with you - you probably won't need the seal -


    wheel and rear brake caliper off - undo the bevel case - ( you can leave the abs sensor in place)

    [​IMG]

    Pull the cover off, be careful that the crownwheel doesn't drop out of the case onto the floor
    [​IMG]

    you may have crap like this inside - you may have nothing

    [​IMG]

    Push the crown wheel gear out from the cover - it's only the seal holding it in place

    [​IMG]

    [​IMG]

    This bearing is toast - but there was no play at all in the rear wheel, just a vibration and rumble when the wheel was rotated


    [​IMG]

    The hardest part is removing the old bearing, you can do it with a couple of small braod faced drifts, keep hitting it around the edges under the bearing and it will gradually lift - obviously don't worry about damaging the old bearing : )

    Put the new bearing on the exhaust down pipes, with the engine running, while your removing the old bearing - you want it very hot

    when it's very hot ( if there are a few bikes, take it in turns to move the bearing from one bikes exhaust to another ) take the bearing and drop it onto the crown wheel - if it's hot enough, it'll just drop all the way down -

    Sorry, image shack has decided to go off line, i'm missing lots of pictures - i'll post the rest later -

    Nice summary!! Its not rocket science, and no worse than trying to fix flat (like when you have to pull the tire from the rim).

    Thanks for showing what a simple job this is.

    Howdy,

    First came this...

    [​IMG]

    Then about 4 miles later...

    [​IMG]

    [​IMG]

    No rumble or funny vibrations, just a sudden violent shuddering in the rear as the wheel flopped eccentricly around the shaft. Major pucker factor. The dealer replaced the bearing under warranty. The worst part is that I was leading a ride for a rally I had organized... The ribbing lasted a longggg time and I still get teased about it. Bike had 28K on it when it blew. 02 model. Has about 45K on it now and no further problems as of yet. I have to admit though that I always have that nagging doubt in the back of the mind. This has been getting louder as I prepare to leave for a week of DS riding in Southwestern Colorado...

    I have heard that there is an inspection or cleaning that can be done that might stave off the impending doom. Anyone know anything about that?
