CAUTION!
Before starting work, stabilizer bars must be coupled in vehicles with separable stabilizer bars. Otherwise, there is the danger of injury caused by unintentional separation.

- Depressurize hydraulic system for separable stabilizer bars using the Vehicle diagnosis, testing and information system VAS 5051.

- Remove wheels.

- Remove rear part of exhaust system:

- Disconnect brake lines - arrow 2 -.





- Remove brake cables from rear axle.

- Disconnect all electrical wires from body to axle.

- Remove left and right air supply.

Installing

Installation is the reverse of removal, with special attention to the following:

- Tighten subframe using the old bolts. They have to be replaced with new bolts following wheel alignment.

- Tighten old bolts to specifications without additional tightening, while doing so.

- After installation, a vehicle alignment must be performed. Refer to --> [ Wheel Alignment ] Wheel Alignment.

- Adjust parking brake.

With Separable Stabilizer Bar

- Bleed separable stabilizer bar. Refer to --> [ Separable Stabilizer Bar, Bleeding ] Procedures.

Continuation for All

- Bleed brake system.

- Install wheels and tires. Refer to --> [ Wheel Bolts, Tightening Specification ] Specifications.
