F550 lubing

I changed the oil yesterday and didn't make too much of a mess that a gallon of kitty litter couldn't handle. I was checking the front suspension and there are grease fitting on this instead of "lifetime lubed" fittings. Does anyone have a pdf for the 550 lubrication. Attempts to find online bring up references to the 250 and 350 but not a 550 4WD. I'm going back under today but do the U-joints and drive shaft section have zerks also? My previous DP, Freightliner chassis, had a bunch.

If you'd like, I can scan the pages from the owner's manual into pdf format, if that helps, unless you are looking for something else?

I didn't realize it was in the owner's manual. I'll take a look. Usually stuff like that is in service manuals. Thanks

EDIT adding; I checked the owner's manual and only says lube the suspension/front end of 4WD. No diagram of zerk locations. I counted 7 zerks on front and none on U-joints and drive shaft.
