How It Works: Yukon Dana 30 CAD Delete Kit

What is CAD?

What is CAD? It’s not short for Cadillac… In this case it’s not the acronym for Computer Aided Design… For our purpose CAD stands for "Central Axle Disconnect." At its core, the Yukon Dana 30 CAD Delete Kit blocks off the vacuum actuated engagement of four-wheel drive in Dana 30 differentials.

Select Jeep vehicles produced from 1984 to 2001 are equipped with the automaker’s reverse rotation Dana 30 differential that’s outfitted with the Central Axle Disconnect (CAD) system. The system components, located on the passenger-side axle tube, consist of a two-piece splined shaft and a coupler that a vacuum-operated shift fork actuates to connect or disconnect the axle, which engages or disengages four-wheel drive.

Dana 30 Heritage

The Dana 30 has been the go-to front diff for the Jeep Wrangler since the model’s Jurassic Period… CJ-5 models of the early 1970s. Available in high- and low-pinion versions as well as standard and reverse rotation versions, the Dana 30 is an important building block in the Jeep hierarchy. There are tons of aftermarket parts for this differential and spares waiting for rescue in junkyards across the country.

CAD Versus The Elements

Time is no friend to the CAD system. The vacuum lines can crack, the vacuum motor can fail, or the system can be compromised in another manner, and cause the Jeep to be stuck in two-wheel-drive… that’s no fun. Further, the two-piece axle is not as strong as a one-piece design. Fortunately, the stronger and more reliable one-piece axle from a TJ or ‘non-disconnect’ XJ are direct swaps. The catch… sealing the housing post-swap.

Yukon To The Rescue

Enter the Yukon Dana 30 CAD Delete Kit. It consists of a disconnect housing blocking plate, gasket, and inner axle seals that will accommodate a one-piece axle design.
