An Axle Repair Tooling Shaft is a specialized service tool used during rear axle differential setup and adjustment procedures and allows proper positioning of the pinion assembly so that the correct shim height can be established during differential servicing. Supports accurate setup by simulating the operating position of the pinion during inspection and adjustment. Reduces setup errors and repeat work by providing consistent and repeatable measurements during differential repair.Attributes:• Assists technicians in achieving correct pinion depth alignment.• Improves accuracy during differential service and rebuild procedures.• Helps prevent incorrect gear engagement during final assembly.Applications: An Axle Repair Tooling Shaft is used within rear axle differential assemblies during service and repair procedures to set the correct pinion shim height. This placement enables accurate gear alignment, proper contact pattern adjustment, and reliable torque transfer during drivetrain operation.
