1) Desmontar el eje de propulsin traseroo delantero.2) Instalar la herramienta especial (tapn)en la punta del eje de la caja transfer (1) yfijarlo a la caja transfer o anclarlo concable para evitar goteo de aceite de lacaja. Herramienta especial (A): 09928365103) Verter el aceite especificado dentro de
la caja hasta el agujero de nivel de aceitesi se ha desmontado el eje delantero.4) Cambiar la caja transfer a 4H-lock de laforma siguiente .[Sin cambio]Quitar la tuerca de la palanca (2) de lacaja transfer, empujar la palanca hacia
abajo para conseguir 4H-lock position (3)y fijar la palanca con la tuerca.[Cambio con motor]Cambiar la caja a la posicin 4H-lockgirando el interruptor de la caja transfer.
