• A standard puller, wrench or improvised tool cannot engage the factory service points correctly

• Accurate bearing, gear, cable or pulley positioning is required during assembly

• Corrosion, press fit or retained components require controlled service force

• The applicable workshop procedure calls for the listed OEM special-tool number
