Learn the step-by-step procedures for tearing down, rebuilding, and improving the most popular Jeep transfer cases by using this comprehensive manual written with the do-it-yourselfer in mind.
The transfer case is arguably the heart of any Jeep. It’s the key component that splits power to the front and rear axles and ultimately provides the traction that has allowed Jeep to maintain its legendary off-road status for nearly 80 years. Jeep used several different transfer cases in its various vehicle models, many of which have an excellent reputation and remain sought after today. But even the best mechanical components can wear over time and need periodic service to ensure decades of reliable service.
While transfer cases may seem complicated on the surface, they can be successfully rebuilt by a competent weekend mechanic with surprisingly few specialized tools. Jeep Transfer Cases: How to Rebuild covers rebuilding the most popular and widely used transfer cases found in dozens of Jeep models for decades, including the Dana 18, Dana 20, Dana 300, and the NP231. The entire rebuild process is shown from beginning to end while providing valuable pointers, complete specifications, and a list of the specialized tools that are required. Also included are tips for upgrading these cases for better strength and off-road performance, including deeper low-range gearsets, slip-yoke eliminator (SYE) kits, and much more.
Author Trenton McGee has written hundreds of technical articles on virtually every component on 4x4 vehicles for off-road magazines. McGee takes a layman’s approach to tackling complex tasks while avoiding complex technical jargon.
This book will help you better understand your transfer case and determine if rebuilding your transfer case is for you or your local 4x4 repair shop.r
