Gatorac:
Rick makes a good point about keeping the
oil in the center section not the axle tubes (solid axle only). Seals-It and Speedway Motors carry the seals for the inside of the axle tubes. There are many other factors that could cause your race and bearing pitting/delaminating. Is there another wear spot in the race 180 degrees from the one pictured? If so, it could be an out-of- round bore for the race caused by a burr, chip, etc. When the caps are torqued, the race becomes egg shaped and then the rollers have extra preload across the smaller diameter. Look at the country of origin on the bearings, it is getting difficult to find "Made in USA" but the top differential guys sell them. In addition, not all gear oils are created equal, great reading at
