My local Honda dealer had moly 60 for $26.00 for a small tube, and when I opened it, it was only half full ???. On the service manual only the shaft spline that goes in the coupling gear calls for moly grease, and yes, it'll get mixed up with the gear oil. I'm not so sure you need any moly 60 there.
The service manual calls for lithium grease for the front part (spline) of the shaft and the wheel spline as well, and that's what I did.
It gets a bit confusing when you read one thing in the manual and then you read good reviews of people using Moly 60 all around on FJRs, Gold wings, etc. I wonder if that's what their service manual calls for or if they're ignoring their manuals and use moly 60. Maybe next time I'll use moly 60 on all 3 splines :-\ .
