The Ford 8.8- and 9-inch need to be rebuilt after extensive use and need a variety of different ratios for top performance and special applications. This Workbench book provides detailed step-by-step photos and information for rebuilding the differentials with the best equipment and installing the gear sets and converting to posi-traction for a variety of applications. It shows how to disassemble the rear end, identify worn ring and pinion gears and other damage or wear, and proceeds to show step-by-step rebuilding of the differential. It also explains how to select the right differential hardware, bearings, seals, and other parts, as well as how to set ring and pinion backlash, so the rear end operates at peak efficiency.

Aftermarket 9-inch performance differentials from manufacturers, such as Currie, Moser and Strange, will be reviewed and the reader will learn how to rebuild and set-up these high-performance aftermarket differentials. In addition, the book provides a comprehensive 9-inch identification chart to ensure readers properly identify the model and specifics of the differential. Chapters include axle identification, inspection, and purchasing axles for rebuilding, differential tear down, ring and pinion gear removal, inspection and reassembly, drive axle choices and more.
