For my truck, I bought Federal Mogul bearings at O'Reilly. The outers are part number A3 for either disc. The inners are part number A6 for the 1" rotors, or part number A5 for the 1-1/4" rotors (yes, I got the wrong ones the first time
). The inner seal was part number 8871, but I forget what brand that was. These part numbers are for 1/2 ton 2WD.
