- (4) Remove the hanger on the TWC side as shown in the figure and set the hanger aside.
-
- (5) Remove the steering shaft cover. (See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION [WITH ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].) (See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION [WITHOUT ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)
- (6) Disconnect the steering shaft from the steering gear and linkage. (See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION [WITH ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].) (See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION [WITHOUT ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)
- (7) Remove the steering dust cover. (See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION [WITH ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].) (See STEERING WHEEL AND COLUMN REMOVAL/INSTALLATION [WITHOUT ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)

- (9) Remove the front auto leveling sensor. (Vehicle with discharge headlight system) (See AUTO LEVELING SENSOR REMOVAL/INSTALLATION.)
-
Caution
-
• Refer to the SST instruction manual for the basic handing procedure.
7. Install the SST using the following procedure.
- (1) As shown in the figure, set the rear shafts of the SST to the left and right shock absorber nuts.
-
- (2) Install front foot No.2 to the left/right front shaft of the SST, then align the groove of the front shaft of the SST with the folded up part of the vehicle as shown in the figure.
-
- (3) Adjust the positions of the SST side bars so that they are the same height (left and right) and horizontal. Make sure each joint is securely tightened.

Warning
-
• Improperly jacking a transaxle is dangerous. It can slip off the jack and may cause serious injury.
-
Caution
-
• To prevent the torque converter and transaxle from separating, remove the transaxle without tilting it toward the torque converter.
8. Remove in the order shown in the figure.
9. Install in the reverse order of removal.
10. Add the ATF. (SeeAUTOMATIC TRANSAXLE FLUID (ATF) REPLACEMENT [FS5A-EL].)
11. Perform the following test according to the service item. (See MECHANICAL SYSTEM TEST [FS5A-EL].) (See ROAD TEST [FS5A-EL].)
