4 wheel drive assist lubing

[IH3444]

I was also reading the manual about lubing the 4wd assist driveshaft. It states in the manual this should be done every 50 hours. It doesn't go on the describe where to lube, what needs to be lubed.....Is it the drive splines?

I believe most of the 4wd TCs have a zerk right behind the front axle, immediately in front of where the driveshaft connects.

I have two on the axle pivot point, and one on the shaft.

Thanks, I knew about the axle pivot point......but was wondering if I should remove the shields and apply oil lube to the splines. I have seen in the past splines which ran dry and destroyed themselfs.......
