### Removal Procedure

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

1. Disconnect the negative battery cable.
2. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
3. Disconnect the electrical connector from the ALC sensor.
4. Unclip the wires from the rear axle cradle.

6. Remove the ALC sensor bolts.
7. Remove the ALC sensor.

### Installation Procedure

1. Install the ALC sensor.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

2. Install the ALC sensor bolts.

Tighten
Tighten the ALC sensor bolts to 14 N·m (124 lb in).

3. Secure the link rod to the ALC sensor arm with the locking tabs.
4. Route the ALC sensor wiring to the rear axle cradle.
5. Clip the ALC sensor wiring to the rear axle cradle.
6. Connect the electrical connection.
7. Lower the vehicle.
