The horror story about dry splines made me do it ! !
Remove rear wheel, (see owners manual)
Remove the three chrome 'acorn' nuts on driveshaft tube.
Slide out driveshaft with rear hub.
Put 19mm hex tool in vise, slide on rear hub with axle vertical. (watch vent hole upper inside of hub, for drips)
Compress driveshaft fully against spring in hub. (to open room for grease) using bar type sliding clamp. ( a really big one)
With c-v joint grease needle on grease gun, and slant of needle point away from driveshaft, (not to cut/nick seal),
carefully insert needle between shaft and seal into void created by compressing driveshaft.
Pump it up ! ! Do this in several spots around driveshaft.
Then remove clamp, and push/pull driveshaft to distribute the grease on splines (at least that's the plan) Do not over fill with grease,
it's gotta have some room to move.
schematic notes from other member post about trouble areas
my notes to correct the position of parts for better understanding of compressing shaft to gain a void for grease
Then do the 'Lamonster' driveshaft install: https://www.m109riders.com/forum/inde...pic,830.0.html I tried the 'stab' but no luck. RRH
ps: Put a little grease on U-joint splines too. IF you suspect that hub end of shaft is totally dry, and or damaged, buy a new seal, and pull it apart, or take it to dealer.
