[QUOTE="PoManNox, post: 24035, member: 8300"] Any thread on a 2018+ seems to be all over the map on this topic. I believe those under pics of a 2025 look like my 2021. Having been all over the drivetrain on my 2021 LT AWD model changing fluids, the facts are, there is an electronic front axle disconnect on 2018+ and a clutch at the input of the rear carrier. With all 4 wheels on the ground and AWD not turned on, you should be able to spin the prop shaft by hand. It basically free-wheels. The input gearing on the transfer case is going to be spinning any time the front wheels are rolling, regardless of AWD on or not, same with the rear carrier/diff. When you select AWD, the front axle disconnect engages and puts power to the transfer case, causing the prop shaft to be under power. If front wheel slip is detected, the electronically actuated wet clutch at the input of the rear diff engages, sending power to the rear wheels. [/QUOTE]
