WARNING: This page is about a different variant/trim than selected.

Set the differential assembly to the clutch housing case assembly.
Push and fit the tapered roller bearing outer race by hand.
To fit the tapered roller bearing outer race, rotate the differential assembly by hand about 10 times.

Put the straight edge on the mating surface of the transaxle case assembly and measure the dimension "B" with a vernier caliper.
Select the shim whose dimension is the difference between "B" and "A."
Install the differential assembly to the clutch housing case assembly. Tighten the transaxle case bolts to the specified torque.
Tightening torque: 29.0 ± 5.8 N.m (21 ± 3 ft-lb)
