Incorrect Service Procedure when Installing the Rear Differential Clutch Drum Assembly Can Cause Ticking Noise

When installing the Differential Clutch Drum Assembly to the pinion shaft of the Differential Assembly, one of the first steps is to align the clutch with the pump and pump bushing. This is done by placing alignment tool J 46607 in the splines of the clutch. Twist the alignment tool back and forth to align the pump and bushing. With a properly aligned clutch, the groove on the J 46607 will be flush with the drum as shown. Remove the tool by pulling straight out.

Please perform this step correctly, as shown in SI. Do not attempt to force or hammer the alignment tool into the clutch drum. Also, please do not use the pinion shaft to perform the alignment function by installing the clutch drum onto the shaft without using the alignment tool. Using the alignment tool correctly assures that no damage occurs to the internal components of the clutch drum. If damage occurs to the clutch, the pump, or the pump bushing, a ticking noise will result.

Note: Changes are being made to the assembly procedure in eSI to reflect the above information.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
