Well its definitely the "minimum", The difference after i greased and drove was noticeable

New here, I'm sure this topic has already been discussed, I've been watching youtube topics on GM not doing their due diligence with fluids and front end. So I was doing a 1000 mile oil change on my "25" SIERRA 2500, it was a quart and a half low when I drained. So I was curious about the front end grease fittings and the stories of gm not greasing them, I inspected them and sure enough BONE DRY! those boots had nothing.. I greased all of the 9 grease fitting up front too. Took ole big red for a spin and I could tell the difference in the front end immediately, . I don't understand what gm's logic is? the grease fittings are all there?. So I wanted to do 1 more thing so I checked the rear diff oil, And to my surprise the oil was to spec level. At least that was done.
