A clicking noise is noticed from the area of the rear axle differential, either when: Transitioning from driving forward to backing up
During load reversal while driving (i.e., engine load to overrun, etc.) Refer to video attached to this bulletin.
Cause
A slight amount of movement can exist between the mating surfaces of the propeller shaft (aka driveshaft) coupler notches and the matching splines on the rear differential.
Correction
Apply sealant to the driveshaft/rear differential connection. The sealant will harden and prevent the relative movement between splines of the two components. Procedure Reproduce the noise during a brief road test while the drivetrain is at operating temperature.
Hint:
Select the Sport display in the Central Information Display using the path My Vehicle- Technology in Action- Sport Displays. If needed, set the units to pound-feet (lb-ft) using the path My Vehicle- iDrive settings- Units- Torque. The noise occurs at an engine torque between 37 and 73 lb-ft.
With the vehicle stationary, select transmission gear “R” and accelerate slightly with the brake pedal depressed. The noise should now occur once. Then select “D” and accelerate slightly against the brake. The noise should now occur again.
Apply Loctite 648 sealant (or equivalent) to the connection between the driveshaft and the rear axle. Refer Repair Instruction 26 11 000 “Completely Removing and Installing the Propeller Shaft”. Note: The updated repair instruction is available with ISTA 4.12.3x, as of late July 2018
The driveshaft does not need to be removed from the vehicle, only the rear joint

If you are using a Main labor code for another repair, use the Plus code labor operation 26 11 507 instead of 26 11 000.
Refer to KSD2/AIR for the corresponding flat rate unit (FRU) allowances.
Work time labor operation code 26 99 000 is not considered a Main labor operation. Also, since the “work time” FRU allowance to be claimed is specified, a separate punch time is not required. However, it still requires an explanation on the repair order and in the claim comments section.
