I know from searching the front drive shaft fitting discussions that the 2019+ 4x4 trucks don’t have a serviceable u joint/ CV / Cardon joint (whatever the correct term is) so the diesel supplement manual is wrong. The diesel supplement manual also says to “inspect front end, and lubricate-if equipped with serviceable fittings” every 7500 miles. I searched around under the front end and I can’t find any needle or zerk fittings. I would assume they are referring to steering or suspension components. So has anyone found and greased any fittings on a 2019+ truck?
