    First Name:
    SR5 TRD, V6 4x4
    Donahoe suspension (Icon Vehicle Dynamics) 4.88 gearing in rear diff.
    A while back I upgraded to 4.88 precision gear seals. Apparently Toyota had a few different rear-ends during this time and so the precision gear kit pinion is has a different outer-diameter at the oil than the OEM part did. I had a seal installed by Toyota that they got through NAPA auto parts. Unfortunately I lost the box that had the part number. Does anyone know what the Inner-diameter of the seal seat in the differential housing is? And do you know what the outer-diameter of the precision gear pinion sealing area is? I have a 2004 Toyota Tacoma.
