Jeep Wrangler YJ Posi-Lock Install

The Jeep Wrangler YJ came with a split front axle that was locked together by a vacuum switch when you put the Jeep in four wheel drive. The Posi-Lock cable system replaces the vacuum with a cable you actuate in the cabin of the Jeep manually. That way you can be sure it engages every time. I get the system installed in this video.
