Removing
Before starting work, stabilizer bars must be coupled in vehicles with separable stabilizer bars. Otherwise, there is the danger of injury caused by unintentional coupling.
- Remove drive axle. Refer to => [ Drive Axle ] Rear Suspension.
- Secure brake disc using a wheel bolt - arrow -.
- Remove brake caliper and engage on body with wire.
- Remove brake disc.
- Unclip wire for wheel speed sensor from retainer.
- Remove ABS wheel speed sensor.
- Unhook parking brake cables at wheel bearing housing.
- Remove brake shoes of parking brake.
Wheel Hub, Pulling Out
Before starting work, stabilizer bars must be coupled in vehicles with separable stabilizer bars. Otherwise, there is the danger of injury caused by unintentional coupling.
