| ST 18270KA020 | SOCKET (E20) |
Tightening torque:
64 N·m (6.5 kgf-m, 47.2 ft-lb)
8. Measure the backlash, and select the washer.
(1) Install the SUBARU genuine axle shaft to differential case.
| Part No. 38415AA070 | Axle shaft |
(2) Using ST1 and ST2, insert the ST2 through the window of differential case. Measure the backlash of the gear.
NOTE:
• Measure the backlash by applying a differential bevel pinion tooth between two differential bevel gear teeth.
• When measuring, fix the differential bevel pinion in place with a screwdriver covered with cloth, or a similar tool.
| ST1 498247001 | MAGNET BASE |
| ST2 498247100 | DIAL GAUGE |
Specification:
