You don't have to use a lot. Just clean all well, I use brake cleaner spray and old underwear

. Then just paint a coat of the black gue on the spline surfaces. I paint both the male and the female sides. Use a Zip tie to lift (prop up) the end of the shaft so that the drive starts to go in, then pull the tie out and push the drive all the way. Torque wrench please. Slow until everything clicks even at 20 Nm first, then to 60Nm. The manual says 64Nm.
