Figure 13 - Transfer Case
F Series 4x4's and Broncos experiencing a 4W to 2W transfer case jump-out condition should be serviced by replacing the drive sprocket (see Figure 13)
with an E2TZ-7177-C drive sprocket.(Refer to l985 Truck Shop Manual l6-86 ford disassembly/assembly instructions.) This new sprocket has a step
lock cut into the spline teeth which will prevent future jump-out. Inspect the E0TZ-7106-A lock-up collar and E0TZ-7100-B shift collar hub and replace
if the engaging face of the spline teeth is worn or damaged.
