Don't have to grease every time it's looked over. That's OCD. Rule of thumb--Mechanical engines OTR 15,000 full service, 7,500 short. Extended full service 30,000 with a short every 10,000. Electronic engines. On/Off road grease every 7,500, oil is what ever owner does for conditions. * So some can get a idea---most any trucks built from 2016 up have non greaseable U-joints unless spec'ed otherwise. Out of the millions of miles my old company puts on and the some 90 tractors that have sealed U-joints---Only had one have a issue--just one mind you. Penske on there rigs---Full service intervals are------------------------------------------------- 55,000 for heavy haul, tractor with drop. oil change 65,000 for 80,000 GVW, depending sometimes 70,000. oil change. Greasing king pins, steering, drop axle only done at major oil change intervals. With air disc--nothing to grease.
