5. Measurement of backlash (Selection of washer)
(1) Install the SUBARU genuine axle shaft to differential case.
| Part No. 38415AA070 | AXLE SHAFT |
(2) Measure the gear backlash using ST1 and ST2, and then insert the ST2 though the access window of case.
| ST1 498247001 | MAGNET BASE |
| ST2 498247100 | DIAL GAUGE |
NOTE:
• Measure the backlash by applying a differential bevel pinion tooth between two differential bevel gear teeth.
• When measuring, fix the differential bevel pinion gear in place with a screwdriver covered with waste cloth, or a similar tool.
Standard:
0.13 — 0.18 mm (0.0051 — 0.0071 in)
(3) If the backlash is not within specification, select a washer from the table below.
