Heavy Duty Retainer
Many times early Broncos are so modified from stock that it's hard to identify what is actually in your Bronco. Some identification is simple like small bearing vs large bearing.
Small bearing 1.374 I.D. / 2.834 O.D. (Stock for some 66-75 Bronco)
Large bearing 1.529 I.D. / 3.150 O.D. Stock for some 66-77 Bronco
Large w/tapered roller bearing 1.557 I.D. / 3.150 O.D. (Stock on 1979-86 Bronco's and F150's) (Also fits most 73-78 Bronco and F150's with 31 or 35 spline axles).
The 3/8 LARGE retainer also fit most 80-86 F Series and Broncos.
