Dana 60 Reverse Rotation Rear Axle

Published by Trails Less Traveled on April 9th, 2004

 

A 1979 Ford reverse rotation Dana 60 front axle housing was cut apart to build the rear axle for the TLT CJ7. Currie re-tubed the housing and added billet Ford 9" big bearing housing ends. The width was set to 63", WMS to WMS.

The Ford 9" housing ends allow for the greatest number of aftermarket options regarding rear brake selection. We chose to install the Wilwood Pro Street kit with mechanical spot caliper parking brakes.

The axle was assembled using Curries own 1.5"x 35 spline, semi-floating chromoly axle shafts. The weight and horsepower of this vehicle did not mandate a full floating rear axle, and we not anticipate flat towing the vehicle, so rear hubs were not needed.

A full spool was installed in the rear axle because a selectable locker did not offer the same benefits in the rear as where we installed the ARB Air Locker up front. The rear axle was fitted with the same 5.13:1 ring and pinion ratio as was used up front. A 1350 series yoke with u-bolts instead of straps was used for reliability.
