Focuses on the disassembly, inspection and step-by-step rebuild of the most popular high-performance differentials. Axles and differentials are not incredibly complex components, but there are some specific steps to follow for rebuilding, upgrading, and setting them up properly, and this book demystifies the process and explains it in detail.

In this Workbench series title, the focus is on the disassembly, inspection and step-by-step rebuild of the most popular Jeep, Dana and Chrysler high-performance differentials.

The A-904 and A-727, debuting in 1960 and 1962, respectively, are 3-speed automatic Chrysler TorqueFlite Transmissions. In Mopar circles, they have become synonymous with strength, durability, and performance. In fact, 43 years after its first application, A-904s were still found in the Jeep lineup! TorqueFlites are known for their dependability, but many have endured a tremendous amount of abuse over 50-plus years when hooked up to V-8 Mopar powerplants. There is little doubt that some of these automatics could be prone to failure, or at least need a thorough rebuild. Tom Hand shares his decades of experience rebuilding TorqueFlite transmissions with chapters dedicated to troubleshooting, disassembly and reassembly, performance modifications, post-installation procedures, and the most thorough source guide offered in print, ever. The author walks you through the TorqueFlite rebuild with color photos showcasing step-by-step procedures with highly detailed, easy-to-follow text. This book will keep money in your pocket and add experience to your résumé, but more important, it will help you get your Mopar back on the road! p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Arial}

Naturally aspirated Mopar Wedge big-blocks are quite capable of producing between 600 to 900 horsepower. This book covers how to build Mopar's 383-, 400-, 413-ci, 440-ci engines to these power levels. Discussed is how to select a stock or aftermarket block for the desired performance level. The reciprocating assembly is examined in detail, so you select the right design and material for durability and performance requirements. Cylinder heads and valve train configurations are crucial for generating maximum horsepower and torque and this volume provides special treatment in this area. Camshafts and lifters are compared and contrasted using hydraulic flat tappet, hydraulic roller and solid flat tappet cams. Also, detailed engine builds at 600, 700, 800, and 900 horsepower levels provide insight and reveal what can be done with real-world component packages.

The venerable Jeep 4.0-liter inline-six engine has powered millions of Jeeps, including CJs, YJs, Wranglers, Cherokees, and Wagoneers. The 4.0 delivers adequate horsepower from the factory, but many off-road drivers want more horsepower and torque to conquer challenging terrain, which means these engines are often built and modified. The Jeep 4.0, or 242-ci, is affordable, abundant, exceptionally durable, and many consider it one of the best 4x4 off-road engines. In this Workbench title, veteran author and Chrysler/Jeep engine expert Larry Shepard covers the rebuild of an entire engine in exceptional detail. He also delves into popular high-performance modifications and build-ups. Step-by-step photos and captions cover each crucial step of the engine disassembly. He shows the inspection of all critical parts, including block, heads, rotating assembly, intake, and exhaust. Critical machining processes are covered, such as decking the block, line boring, and overboring the block. The book provides exceptional detail during the step-by-step assembly so your engine is strong and reliable. Installing a larger-displacement rotating assembly or stroker package is one of the most cost-effective ways to increase performance, and the author covers a stroker package installation in detail. With millions of Jeep 4.0 engines in the marketplace (which are subjected to extreme use), many of these engines require a rebuild. In addition, many owners want to extract more torque and horsepower from their 4.0 engines so these engine are also modified. Until now, there has not been a complete and authoritative guide that covers the engine rebuild and build-up process from beginning to end. Jeep 4.0 Engines is the essential guide for an at-home mechanic to perform a professional-caliber rebuild or a high-performance build-up.

A driveline expert guides you through each step of the rebuild process for 8.8- and 9-inch axle assemblies, so you can confidently complete the work yourself. He explains in detail limited-slip and open differential disassembly, inspection, assembly, final calibration, and break-in. He also shows you how to identify worn ring-and-pinion gears, rebuild clutch packs, set the correct contact pattern for pinion and ring gears as well as the backlash, and much more.

Covers everything you need to know about selecting the most desirable gear ratio, rebuilding differentials and other driveline components, and most importantly, matching the correct driveline components to engine power output.

"OBD expert, tuner, and author Keith McCord explains system architecture, function, and operation. He shows you how to use a hand-held scanner, connect it to the port connector in the car, and interpret the data. But most importantly, he shows you a practical, analytical, and methodical process for tackling a problem, so you can quickly trace its actual source and fix the root cause and not just the symptom..." -- from page 4 of cover.
