Changed the engine oil, always fun and messy, I swear Jeep engineers must lay in bed at night and laugh about the shenanigans they pull on us, changed the diff oils (no drain plug on the front axle, that is a 2021 feature only and .......NO DRAIN PLUG on the rear either!!!! see previous engineer comment). Then the mac daddy of PITA, changing the T-Case fluid with a NextVenture full skid system in place..... counter, 14 bolts to remove the t-case skid just to get to the drain and full plugs...... wahooo, the joys of a Jeep...... the LJ was so much easier to work on, but the 392 is way more fun.......
