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.
