Anyone have a service manual with this in it? I'm talking about the little black bolts that hold the rear driveshaft to the circular yoke flange on the axle. I think they're like 10mm? On an 2012.

 

Earlier models listed torque for rear driveshaft flange as 15 ftlbs.

Why 15 for rear and 81 for front I don't know?

 

Verified. 15 ftlb for both ends of rear driveshaft and transfer case of front. 81 ftlb for axle end of front drive shaft.

The reason is: There are 3 stock CV joints and 1 U-joint. Why they didn't put another CV joint at the front axle is beyond me. The CV joints might not be as durable but they have less high-speed vibration and can be rebuilt for about $100 in parts per joint.
