ISSUE
An audible "pinging" or "creaking" (not a "clunking" noise) may be heard from the driveline when engine torque is initially applied to the driveline such
as when shifting from Park to Drive or Reverse, between Drive and Reverse. The noise may be heard on slight to moderate acceleration from the stop
position, or at clutch release for manual transmissions. The noise occurs when the transfer case rear output flange (yoke) "snaps" across the spline
clearance on the output shaft as torque is applied to the driveline.
ACTION
Replace the transfer case rear output flange with a revised flange. Refer to the following Service Procedure for details.
CAUTION
IT IS VERY IMPORTANT THAT ORIGINAL PART ORIENTATION BE MAINTAINED. BE SURE TO MARK MATING PARTS BEFORE
DISASSEMBLY.
SERVICE PROCEDURE
1.
Remove rear driveshaft assembly to gain access to the transfer case rear output flange nut.
2.
Remove the nut and transfer case rear output flange.
3.
Wipe the output shaft splines with a clean shop cloth (using Brake Cleaner Solvent or some other suitable solvent).
