I did some research on a high temperature moly grease that another member used in another thread, but I couldn't find how much moly it contained. So I'm left wondering how much protection it actually provides compared to Moly 60 and other high moly greases.
Others have suggested CV joint grease as a substitute because it lubricates joints that operate under pressure and high temperature. But CV joint grease is contained within a boot, can't go anywhere, and comparatively there is a lot of grease in the boot. There isn't room for a huge amount of grease in the VN750 driveshaft coupling, the natural action of the shaft in the coupling tends to push the grease away from where it needs to be, and pressures and temps are high. So I'm left wondering "How much moly is required to provide minimal protection for my bike's driveshaft?" I'm more frugal than most, and don't like to spend money I don't have to. However, I used Guard Dog Moly with around 73% moly on my splines. As OlHoss said, it isn't cheap. But compared to being stranded in the middle of nowhere with bad splines and final drive, it's well worth the investment to me.
I currently have over 10,000 miles on my tires and the back looks good for several thousand more. So, do I go ahead and pull the tire, relube, and pull it again in a few months to replace the tire? Based upon the higher moly content of the grease I used, think I'll wait until the tire needs replacing.
I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!
