For 1990-2009 cars

### 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. Remove the three brake pipes from the LSPV (1). Plug the end of the brake pipes to prevent fluid loss and contamination.
4. Remove the two bolts (2) and separate the LSPV assembly from the vehicle frame.
5. Remove the two bolts (1) securing the LSPV load sensing spring bracket to the rear suspension upper arm.
6. Remove the LSPV assembly from the vehicle.
7. Disassemble the load sensing spring (2) and spring bracket from the LSPV lever (3).

### Installation Procedure

Notice: Do not loosen or tighten LSPV assembly nuts and bolts. The LSPV is not serviceable and must be replaced as a unit. Do not attempt to disassemble the LSPV.

1. Assemble the load sensing spring (2) and spring bracket to the LSPV lever (3).
2. Apply multi-purpose grease to the upper pivot point (1) and the lower pivot point (2) of the spring.

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.

3. Install the LSPV load sensing spring bracket to the rear suspension upper arm. Secure with two bolts (1).

Tighten
Tighten the load sensing spring bracket bolts to 23 N·m (17 lb ft).

4. Install the LSPV assembly to the vehicle frame. Secure with two bolts (1).

Tighten
Tighten the LSPV assembly bolts to 23 N·m (17 lb ft).

5. Install the three brake pipes to the LSPV assembly.
6. Bleed the brakes. Refer to Hydraulic Brake System Bleeding in this section.
7. Lower the vehicle.
8. Connect the negative battery cable.

Important: The following conditions must be met before proceeding with this repair:

• | The fuel tank must be full.

• | The vehicle must have the spare tire, tools, jack and jack handle installed.

• | The vehicle must be free from any other load.

• | The vehicle is on a level (horizontal) floor.

9. Adjust the LSPV lever as follows:

9.1. | Push up the LSPV lever until it contacts the stopper bolt. Hold the LSPV lever in position.

9.2. | Measure the length of the load sensing spring (4). The length of the load sensing spring should be 99 mm (3.89 in).

9.3. | To adjust the load sensing spring, loosen the load sensing spring lower bolt (at the suspension arm bracket) and adjust the length.

9.4. | Retorque the bolt after setting the load sensing spring length to specifications.

Tighten
Tighten the load sensing spring bolt to 23 N·m (17 lb ft).
