Differential Shim Selection


Special Tool(s)
Shim Gauge, Differential/Transfer Gear Bearing
307-591 (includes 307-591/1, 307-591/2 and 307-591/3)
  1. Special Tool(s): Shim Gauge, Differential/Transfer Gear Bearing 307-591 (307-591/1 and 307-591/2)
  1. Special Tool(s): Shim Gauge, Differential/Transfer Gear Bearing 307-591/3 (studs)

  1. NOTE: Make sure that the silicone has been cleaned off the machined surface of the transmission case and the torque converter housing before installing the Differential/Transfer Gear Bearing Shim Gauge 307-591/3 (4 spacers) or the preload measurement may be inaccurate.

    Special Tool(s): Shim Gauge, Differential/Transfer Gear Bearing 307-591/3 (4 spacers)
  1. Special Tools(s): Shim Gauge, Differential/Transfer Gear Bearing 307-591/3 (remaining 4 spacers, bolts and washers)
  1. Special Tools(s): Shim Gauge, Differential/Transfer Gear Bearing 307-591/3 (4 nuts and washers)
  1. Rotate the transfer shaft and the differential several times to seat the bearing cups.
  1. Measure and record the smallest and largest preload gap on the Shim Gauge, Differential/Transfer Gear Bearing 307-591/1. Average the 2 measurements to get the thickness of the differential bearing preload shim. For additional information, refer to Specifications in this section for the differential bearing preload shim part number.
    General Equipment: Feeler Gauge.
  1. Measure and record the smallest and largest preload gap on Shim Gauge, Differential/Transfer Gear Bearing 307-591/2. Average the 2 measurements to get the thickness of the transfer shaft bearing preload shim. For additional information, refer to Specifications in this section for the transfer gear bearing preload shim part number.
    General Equipment: Feeler Gauge.
