Drive Pinion Shaft Assembly: Installation
WARNING: This page is about a different car, the 2020 Subaru Impreza. However, it is still accessible from the selected car via links, so may be relevant.
- Remove the front differential assembly.
- Hypoid gear set match mark/No.: The number (A) on top of the drive pinion, and the number on the hypoid driven gear are set numbers for the two gears. Use a pair having the same numbers.
The figure (B) below shows a number for shim adjustment. If no number is shown, the value is zero.
- Place the drive pinion shaft assembly on transmission main case RH without shim and tighten the bearing mounting bolts.
- Perform the adjustment of ST.
- Position the ST (DRIVE PINION GAUGE ASSY) by inserting the knock pin of ST into the knock hole of transmission case.
- Slide the scale of ST with finger tip and read the value at the point where it matches with the end face of drive pinion.
Preparation tool:
ST: DRIVE PINION GAUGE ASSY (499917500)
- The thickness of drive pinion shims shall be determined by adding the value indicated on drive pinion to the value indicated on the ST (DRIVE PINION GAUGE ASSY). (Add if the number on drive pinion is prefixed by +, and subtract if the number is prefixed by -.)
- Select one to three drive pinion shim(s) from the following table for the value determined as described above, and take the shim(s) whose thickness is closest to the said value.
Drive pinion shim Part No. Thickness mm (in) 32295AA031 0.150 (0.0059) 32295AA041 0.175 (0.0069) 32295AA051 0.200 (0.0079) 32295AA061 0.225 (0.0089) 32295AA071 0.250 (0.0098) 32295AA081 0.275 (0.0108) 32295AA091 0.300 (0.0118) 32295AA101 0.500 (0.0197) - Install the front differential assembly.
