The front “diff”/PTU fluid would have to be siphoned out. Chrysler designed it so the unit technically has to be removed from the car to drain the fluid. The rear locking diff has a large fill plug on it which would make siphoning easier than the front one. Both are inherently difficult to do, but not impossible.
Hey can you change the differential fluid on the 2019 Trailhawk ?
