[QUOTE="FJRMGM, post: 821846, member: 164"] Hey - I have a coupling that looks just like that sitting on a shelf in the garage. NO - that groove is not supposed to be there and is the reason for your sometimes oil leak. Last spring I had a problem with oil splooge on the rear wheel of my '05 with 76,000 miles and replaced seals once at a dealer and after a while it leaked again, but usually only after I had ridden a good distance and really heated up the final drive oil. The second dealer I took it took had just replaced that coupling part on another '05 FJR and had a pretty good idea of what the real problem was. And it was because of that groove in the coupling, which allowed a tiny bit of oil past it when the oil was good and hot. I believe it was about $120 for the coupling which took two days to get and another new seal and I have been oil-free ever since. Replace the coupling and the seal. [/QUOTE]
