Installation

The 4 wheel Drive Actuator actually installs quite easily. Locate it on the front axle. Unplug it. Use a large adjustable or correct size wrench and remove the actuator. Reverse to install a new one.

How this four wheel drive actuator works

When you press the button in your vehicle an electrical current passes through the actuator. The actuator is filled with a gas. This gas expands when heated. The electrical current heats the gas the gas builds pressure and forces the plunger out which engages the front axle.

The Problem

There are a number of things that can go wrong to cause you not to be able to engage four wheel drive. Age, damage, and lack of consistent use are the most common reasons for these actuators to go bad. These actuators work in an unfriendly environment. Underneath the car attached to the drivetrain, they are subject to extreme temperature change as well as physical damage from dirt, debris, rocks, etc. The gas inside the actuator can leak out over time and/or from a fracture caused by road debris. There is a mechanical mechanism that can start to stick as time goes on. Sometimes these actuator just plain don't work in extreme cold weather as the gas actually does not get hot enough to expand. Many times these actuators are not used for 9-10 months or more during warm weather. A little moisture penetrating can quickly cause a malfunction. Any one, or combination of these can result in your 4WD system not engaging or not staying engaged.
