REAR UPPER ARM REMOVAL/INSTALLATION [4WD]

id0214008008a2

Caution
•  Performing the following procedures without first removing the ABS wheel-speed sensor may possibly cause an open circuit in the harness if it is pulled by mistake. Before performing the following procedures, remove the ABS wheel-speed sensor (axle side) and fix it to an appropriate place where the sensor will not be pulled by mistake while servicing the vehicle.
Note
•  The rear upper arm inner bolt cannot be tightened completely with the rear upper arm installed to the vehicle due to the narrow operation space. Therefore, mark the position before removing the rear upper arm, align the rear crossmember and rear upper arm markings when installing the rear upper arm, and tighten the rear upper arm inner bolt completely before installing the rear crossmember component to the vehicle.

1.  Remove the presilencer. (See EXHAUST SYSTEM REMOVAL/INSTALLATION [MZI-3.7].)

2.  Remove the presilencer insulator.

Caution
•  Perform the work using a garage jack. When jacking up the rear suspension with unloaded condition, to prevent bending the front of the vehicle, support the jack up point for the front crossmember using a garage jack.

7.  Jack up the rear suspension with unloaded condition.

Note
•  Jacking up the rear suspension with unloaded condition will lighten the force on the bushing and make it easier to perform the procedure.

8.  Mark the rear upper arm and rear crossmember shown in the figure.
