We removed the factory emergency brake and replaced the original flange yoke with a regular 1310 yoke. This allows for more driveshaft angularity. It’s the same coarse-spline yoke found on Dana 20 transfer cases and Dana 25, 27, and older 44 axles. You need to grind the retainer a bit and add a 1⁄16-inch spacer (washer) under the yoke for proper clearance. Torque the yoke nut to 100 ft-lb.
