To raise the car and support it safely, begin with the front wheel speed sensor by separating the electrical harness in the junction box located in the wheel housing, noting that the left front junction box has an illustration while the right front features a single harness connector. Next, unscrew the sensor mounting bolt at the steering knuckle. When installing, apply a thin coat of Staburags®NBU 12/K or an equivalent grease to both the speed sensor and housing, with installation being the reverse of removal. For the rear wheel speed sensor, again separate the electrical harness in the junction box within the wheel housing, where the right rear junction box is illustrated and the left rear has a single harness connector. Unscrew the mounting bolt on the rear wheel bearing carrier, and similarly apply a thin coat of Staburags®NBU 12/K or equivalent grease during installation, which follows the reverse order of removal.
