Some 2021-2023 Tahoe, Suburban, Yukon and Escalade models may have a right rear door (Fig. 17) that requires alignment. If the rear door is not flush or sticks out excessively at the bottom when closed, align the door following the alignment procedure in Bulletin #22-NA-179.
Fig. 17
To align the rear door to specification, it will be necessary to remove the striker to gain access to the door striker net slots in the body. Both the upper and lower slots will need to be modified for proper door alignment. (Fig. 18)
Fig. 18
The bulletin details the modification procedure along with how to reinstall the striker. The striker must be parallel to the bodyside and not rotated. Closing the door flush to the mating panel will allow the door latch to position the final location of the striker. (Fig. 19)

Once the striker is properly positioned, the bolts can be torqued to specification. Alternate torquing is recommended to prevent the striker from rotating.
Refer to Bulletin #22-NA-179 for the complete alignment procedure and additional information.
