Disassembly and Assembly: Disassembly

WARNING: This page is about a different car, the 2018 Nissan Titan XD and 2018 Nissan Titan. However, it is still accessible from the selected car via links, so may be relevant.

Differential Case Assembly 

NOTE: If the collapsible spacer is to be reused, a torque to rotate measurement needs to be performed and recorded. After re-assembly, set the preload to the measured torque to rotate and add the additional preload torque of 0.6 (0.06, 05).
