An Axle Repair Tooling Shaft is used during rear axle differential setup and repair 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 in consistent setup results across repeated repairs.• Improves accuracy during differential service and rebuild procedures.• Helps technicians determine the correct shim thickness during setup.Applications: An Axle Repair Tooling Shaft is used inside the rear axle differential housing during service and repair operations. It helps set the correct pinion shim height by positioning measuring components accurately, allowing proper gear alignment and smooth differential operation after assembly.
