Hello,
I have an '08 2500 4X4 with a 6.7 and a G56 manual 6 speed. I was doing my first oil change and lubrication today. The only grease fittings that I found were on the tie rod ends, in addition to that needle fitting in the front U-joint. Is that all that has to be greased, or did I miss some? Thanks in advance for your help.

 

That's all there was on my truck, until I changed the u-joints on my rear drive shaft. Now I have three more fittings to grease.
