13.1. | Remove the wheel drive shaft inboard flange bolts from the inner axle shaft. |
Disconnect the wheel drive shaft from the inner axle shaft.
13.2. | Support the wheel drive shaft in order to not over flex the CV joint. |
13.3. | Remove the inner axle shaft using a hammer and a brass drift. |
Installation Procedure
Caution: Refer to Fastener Caution in the Preface section.
- If only the left side inner axle shaft was removed, install the shaft by performing the following steps:
1.1. | Install the inner axle shaft into the differential case side gear using a soft-faced mallet until the retaining ring on the inner axle shaft is fully seated within the groove in the differential case side gear. Pull back on the inner axle shaft to
ensure that the inner axle shaft is properly retained in the differential case side gear. |
1.2. | Connect the wheel drive shaft to the inner axle shaft. |
1.3. | Install the wheel drive shaft inboard flange to inner axle shaft bolts and tighten to
79 N·m (58 lb ft). |
- If the right side inner axle shaft and/or housing was removed, install the shaft and/or housing following the steps below.
- Install the new inner axle shaft bearing and the new seal to the inner axle shaft housing. Refer to
Front Drive Axle Inner Shaft Seal and Inner Shaft Bearing Replacement.
Note: Do not install the inner axle shaft completely into the inner axle shaft housing at this time.
- Install the inner axle shaft (1) into the inner axle shaft housing (4).
- Install the new inner axle shaft housing gasket (3).
- Install the inner axle shaft (1) and the inner axle shaft housing (4) to the differential carrier assembly.
- Install the inner axle shaft housing bolts (2) and tighten to
40 N·m (30 lb ft).
- Install the inner axle shaft housing nuts to the bracket and tighten to
100 N·m (75 lb ft).
- Install the inner axle shaft into the differential case side gear by doing the following:
9.1. | Turn the inner axle shaft and align the splines of the inner axle shaft with the splines on the differential side gear. |
9.2. | Install the inner axle shaft into the differential case side gear using a soft-faced mallet until the retaining ring on the inner axle shaft is fully seated within the groove in the differential case side gear. |
9.3. | Pull back on the inner axle shaft to ensure that the inner axle shaft is properly retained in the differential case side gear. |
- Install the wheel drive shaft inboard flange to the inner axle shaft.
- Install the wheel drive shaft inboard flange to inner axle shaft bolts and tighten to
79 N·m (58 lb ft).
Note: The following service procedure is for vehicles equipped with RPO HP2 (Hybrid).
- Install the electric motor for the steering gear.
