For my 2016.5 CX-5 (KE model), I downloaded the manual. It contains the 2014 vintage data, specs, service procedures. @ pp 4559-4565, there's a section on "Driveline/Axle" and dealing with the propeller shaft, including listing the various bolts and their torque values.
If you download the right manual, it ought to show you everything related to the parts you're going to be dealing with.
