2.Assemble the bearing race to the ring gear and differential.

Note
• Bearing race size: Outer diameter approx. 80 mm {3.1 in}

• If there is a malfunction, disassemble the ring gear and differential and replace the taper roller bearing with a new one. (See RING GEAR AND DIFFERENTIAL DISASSEMBLY [FW6A-EL/FW6AX-EL].) (See RING GEAR AND DIFFERENTIAL ASSEMBLY [FW6A-EL/FW6AX-EL].)

4.Remove the bearing race.

Differential Journal Inspection

1.Measure the inner diameter of the journal (front side) shown in the figure.

Note
• When measuring, measure near the center of the journal avoiding the oil groove, and then calculate the average value of the X and Y directions as shown in the figure.
• Recommended measuring instrument: Cylinder gauge or caliper gauge
• The inner diameter of the journal (front side) differs depending on the vehicle model.

Maximum:
Type A: 30.048 mm {1.1830 in}
Type B: 33.545 mm {1.3207 in}
• If it is more than the maximum specification, disassemble the ring gear and differential and replace the differential gear case with a new one. (See RING GEAR AND DIFFERENTIAL DISASSEMBLY [FW6A-EL/FW6AX-EL].) (See RING GEAR AND DIFFERENTIAL ASSEMBLY [FW6A-EL/FW6AX-EL].)

2.Measure the inner diameter of the journal (rear side) shown in the figure.

Note
• When measuring, measure near the center of the journal avoiding the oil groove, and then calculate the average value of the X and Y directions as shown in the figure.
• Recommended measuring instrument: Cylinder gauge or caliper gauge
• The inner diameter of the journal (rear side) differs depending on the vehicle model.

Maximum:
Type A: 30.048 mm {1.1830 in}
Type B: 33.545 mm {1.3207 in}
• If it is more than the maximum specification, disassemble the ring gear and differential and replace the differential gear case with a new one. (See RING GEAR AND DIFFERENTIAL DISASSEMBLY [FW6A-EL/FW6AX-EL].) (See RING GEAR AND DIFFERENTIAL ASSEMBLY [FW6A-EL/FW6AX-EL].)


Differential Backlash Inspection

1.Perform the following the inspection and measurement/adjustment in the order and replace a malfunctioning part with a new one.

(1)Drive shaft journal inspection (See DRIVE SHAFT JOURNAL INSPECTION.)
(2)Differential backlash measurement/adjustment (See DIFFERENTIAL BACKLASH MEASUREMENT/ADJUSTMENT [FW6A-EL/FW6AX-EL].)
