The False Differential Tube is temporarily installed in place of the actual differential assembly to support accurate pinion positioning. During axle service, the correct pinion shim height is required to achieve proper gear contact and alignment. It allows for measuring and adjusting shim thickness without repeated removal of the final differential components.Attributes:• Enables proper gear alignment during axle assembly procedures.• Supports smooth gear engagement after final assembly.• Helps avoid noise caused by incorrect gear alignment.Applications: The False Differential Tube is positioned in the front axle housing during setup to simulate final assembly, allowing accurate pinion shim height adjustment and proper gear alignment.
