These instructions have been designed for unaltered vehicles. Before you start, check for any variations. Each vehicle may dictate it’s own control mount and cable routing. Therefore, you will need to study the pictures and use your good judgement or seek professional help. Lift kits may govern how and where the cable is routed. Always keep the cable away from heat (exhaust) and rough or sharp edges. If you are concerned about lower cable damage or abrasion, we recom- mend cutting a length (about 3 feet) of 5/8” ID plastic or rubber hose (garden or heater) to be slid over the cable before assembly. Please keep in mind, the warranty is void on heat damaged or abused cables. Before drilling, check for any electrical wires, hoses, etc.
PRE-INSTALLATION VACUUM
Before you remove the CAD (Central Axle Disconnect) vacuum actuator, locate the source of the vacuum transfer case switch. Follow the vacuum lines from the actuator up into the engine compartment to the vacuum switch and to the vacuum source. Using the vacuum cap provided, plug off as close to the engine source as possible without disrupting any other vacuum requirements.
INSTALLATION INSTRUCTIONS
1. Park the vehicle on a clean, flat surface and block the rear wheels for safety. Put the transfer case in 2HI.
2. Locate the factory vacuum actuator housing on the front axle. Place a drain pan under the housing.
3. Remove the vacuum connections at the diaphragm (Fig 4). Note: Picture shows Dana 30; others will be similar.
