Expert Reply:

Hey Cameron, the most common bearings on 7k axles are inner bearing # 25580 and outer bearing # 14125A. If those are your bearing numbers and the inner diameter of your grease seal measures 2.125 inches, you would want bearing kit # BK3-210, which includes the bearings, races and seal.

Should your seal measure have an inner diameter of 2.25 inches, the bearing kit you want would be # BK3-200. For whatever reason the grease seal inner diameter is sometimes one size and sometimes the other without any real rhyme or reason.
