Common Repair Uses

• Wheel-end or differential noise from worn bearings

• Maintenance on front or rear Dana 44 differentials
• Restoration or rebuild work on Jeep Wrangler, Ford Bronco, and Ford F-150 Dana 44 axles

Installation Notes and Tips

Verify axle configuration before ordering, since Dana 44 fitment varies by year, position, and pinion cup style. Confirm inside diameter, width, and bearing type against the original parts during teardown. Clean all sealing surfaces thoroughly and inspect the housing, races, and related components before assembly. Proper setup and preload are important during differential service, so follow factory service procedures for the vehicle being repaired.
