Overview

This overview shows the basic steps for swapping an Early Bronco Dana 44 into a Bronco II or Ford Ranger. The goal is to upgrade the front axle to a stronger solid axle while maintaining proper coil and radius arm placement. The process can be done in a weekend with proper tools and mechanical skills.

Step 1: Before Picture

Step 2: Remove Axle & Suspension

Remove the old TTB axle and suspension components.

Step 3: Front Suspension Removed

Took about an hour to remove everything.

Step 4: Install Dana 44 and Coils

Slide the Dana 44 under the truck. Place the coils on the axle and carefully let the truck down on them. Hook up the shocks. These are Duff early Bronco 3.5″ variable rate coils. Axle is from a 1974 Bronco. 4-inch lift shocks work, 6-inch would be better. Stock coil buckets work, but upgrades are recommended for long-term flex.

Step 5: Radius Arm Brackets

Use radius arm drop brackets from a 1978-79 F-150 or Bronco for proper caster alignment. Axle included 4-degree Duff bushings.

Step 6: Drill Holes for Brackets

Drill mounting holes for the radius arm brackets.

Step 7: Install Brackets

Align the bracket holes with existing frame holes to maintain original wheelbase.

Step 8: Track Bar Mount

Install a track bar mount. Bolt-up is recommended, but welding is optional if comfortable. Mount attaches to existing power steering gear bolts.

Step 9: Finished

After the swap, the axle sits 4 inches higher than the Skyjacker 4-inch lift. Brake, crossmember, and steering connections are omitted for brevity. This swap was done solo in one weekend.
