grease points chart?
 

I've searched here, and it must have been discussed before, but,

can someone give me a definitive chart or list of all the spots I need to be greasing? I don't want to miss any.

I finally powerwashed the underside of my truck - it must be 30 pounds lighter! but now I need to do all the standard maintenance stuff. I'm open for advice on what all I should tackle.

but I know I want to grease up, so how many and where are they all?

Not a whole lot of grease points

Upper and lower King Pins, or Ball Joints, Tie Rod and Drag Link Ends, all U-Joints front and rear, drive lines and the front axle U-Joints at the wheels.

Pretty much just look for anything that pivots is what I do. These trucks are pretty simple. Some of our work trucks have over 50

thanks for the list... but is there a chart somewhere?

Look in your Field Service/Shop Manual, either in the maintenance section or in individual sections of the book covering transaxle, driveline, steering, front and rear end, etc.
If you don't own a manual, you can get one from genosgarage.com. Paperback at around $110, CD version around $35
