What does this stuff mean?
Ok, dumb question, but when I look at the maintenance schedule in the manual I see things like "Inspect and lubricate steering linkage, ball joints, suspension and, if equipped, half shafts, drive shaft and u-joints (Replaces 63p, 73p, 82p, 252p, 253p, 256p, 262p, 272p, 294p)." What does the "Replaces 63p, 73p,....." mean? From what I gather I'm better off not following the schedule as written anyway, but I'm just curious what that stuff means.

Steering linkage is all the joints in the steering system between the steering wheel and the front wheels.
Ball joints are the joints where the control arms connect to the front wheels.
Suspension is a generic term that includes all of the parts that connect the frame to the axles (springs, shocks, etc.).
Half shafts are the cv axles that transmit power from the front differential to the front wheels on a 4x4.
Drive shaft transmits power from the transmission to the differential. 4x2 has only a rear drive shaft, 4x4 has front and rear. Front drive shaft runs from the transfer case to the front differential.
U-joints are the universal joints at both ends of the drive shaft where it connects to the differential and the transmission (or transfer case on a 4x4 front shaft). These allow for up/down motion of the axles when going over bumps or uneven terrain, or when loading compresses the springs.

There are no Lubrications points in the front suspension and drive that are part of any maintained sked except the front Axle of a 4wd..whel bearings etc.
There are specified Lubes to use in cases of involved repair done where parts are taken apart such as drive shaft slip yoke ETC and body parts that may need re-lubing at times such as Door Locks, Window linkages etc...
A search of your owner manual 2018 shows none but normal replacement fluids and lubes in engine oil, Transmission, Transfer case , Rear Axle, Brake fluids, Coolants etc. found in the specifications listings for each engine family.
I believe you have a 2018 2.7 L.
When parts wear out, they have to be replaced.
Only aftermarket parts that have been designed to lube as installed need attention, such as front upper and lower Ball joints.
I have a 2018 that has a worn RF lower ball joint now, to be replaced soon.
Good luck.
