REAR END SETUP MADE EASIER
After I read the article about the 12-bolt rear end in the last issue, I wanter to share a solution to easily set pinion depth, without the hassle of pressing the bearings on and off. When rebuilding integral carrier type differential such as the GM 10 or 12 bolt, after removing the pinion, I remove the original bearings from the pinion (providing they are not destroyed). I take the old bearings and open the I.D. of the bearings with a stone on a die grinder so that the bearings will slip fit onto the pinion shaft. Now I can assemble, and disassemble as needed to set the pinion depth, without having to press the bearings off each time. Then I final assemble the differential with new bearings. I mark the modified old bearings for future use in the same type rear, saving money and time.
