In mid-1971, Ford transitioned the early Broncos from coming with Dana 30 model front differentials, to the much more popular Dana 44 model front end. This beefed up the front end of the 1971 Ford Bronco exponentially and made it much more off-road worthy. This was the biggest change made to the 71 Bronco which otherwise remained pretty much the same as previous years of the Early Bronco.
