How to reach zerk fittings on front driveshaft

How in the world are you supposed to grease the U joints in the front driveshaft? I can't get any grease fittings over the zerks on the front driveshaft, especially the rear U joint.

 

There is a plate you have to remove. You can turn the front shaft by hand, make sure it's not in 4wd.

 

I unscrew the zerk fitting on my gun a few turns so I can slip it over the u-joint zerk, tighten the fitting until snug, grease it, reverse the process, done.

 

I didn’t have to remove anything to get to mine. Everything lined up perfectly first try. I usually don’t have that kind of luck ha

 

Just got to get the right angle(s)...
Do you have an adjustable coupler? Maybe, open it up some?

 

It ain't lined up just right, just move the truck an inch or two and sooner or later they will be facing down

 

12mm socket if I recall correctly.

 

Just did mine two days ago. Shaft should spin freely. Rotate it to the correct position that works for you. The rear is harder, you don’t have to take that cover off. I hit it from the passenger side of the shaft. Went over all the stuff there
