Chevy Differentials: How To Rebuild The 10- And 12-Bolt

Millions of Chevrolet vehicles were built and sold in the 1960s and 1970s, and the great majority of those were rear-wheel-drive models with differentials known as 10-bolts or 12-bolts. High-performance limited-slip versions of these differentials also have been installed in Camaros, Chevelles, Corvettes, and many other GM muscle cars from 1964 through the 1970s, as well as Chevy and GMC trucks. If you have owned a GM performance car from the 1960s or 1970s, you have owned one of these sturdy, reliable, and versatile differentials. Many of these differentials are now more than 40 years old and are due for an overhaul. In Chevy Differentials: How to Rebuild the 10- and 12-Bolt, author Jefferson Bryant walks you through the entire process of disassembling, evaluating, and rebuilding the perfect differential for your GM application. In this step-by-step guide, you learn how to completely disassemble the differential, evaluate components, and select replacement parts. You’re also shown all of the up-todate techniques for re-assembling the differential and axle. Informative sections on axle identification and replacement parts are also provided.
