    Comments about Motive Gear Bearing and Seal Master Kit:

    This kit had good quality parts, but came with parts for two size rear ends, however left out other necessary parts. for instance, it came with seals for the 8.5 and 9.5 inch rear, but it had only the inner bearings and seals. outer axle bearings and seals had to be purchased separately. does anyone really replace all the inner bearings on a rear diff and NOT replace the outer axle bearings and seals at the same time ? the kit also came with NO instructions on how to setup a rear for proper bearing preload, backlash, etc.

      • Q:

        where does the second seal go ?
        one goes on pinion opening ,but where does the other one go?
        also being a "master" bearing and seal kit,this kit should come with wheel bearings/races and axle seals ,they are in the differential also.
