Suspension/Steering Lubrication Every 7,500 Miles

[mopac]

I've hit the 7,500 mile mark on my 2018 Silverado 1500 4WD Crew Cab LT.   The recommended service items include "Lubricate the suspension and steering components" and elsewhere relative to the 1500 indicate "every other oil change lubricate the outer tie rod ends."  

 

I've looked all around underneath the truck and it appears that the ONLY zerk fittings to be found are on the tie rods on each front wheel (picture below).  Are these indeed the only thing on the suspension/steering that needs to be lubed?  Everything else looks to be permanently lubed/sealed.  

 

There's also a recommendation at 7,500 to "inspect power steering for proper attachment, connections, binding, leaks, cracks, chafing, etc."  However, I've seen another post on here when searching this topic that indicates a 2014-2018 Silverado 1500 has an electric power steering unit that doesn't use fluid.  Sooooooo... it would seem that there's little to actually look for/do relative to this recommendation.  Is it just a useless leftover from prior versions of the manual?  I'm not seeing exactly what to check here, based on what I've read the vehicle actually has.
