The Isuzu Trooper, produced from 1984 to 1991, marked the beginning of Isuzu's foray into the burgeoning SUV market. This first-generation Trooper, also known as the "First Generation Isuzu Bighorn" in Japan, was a rugged and capable vehicle built on a ladder frame chassis with a solid front axle and a rigid rear axle. Powered by a 2.3L or 2.6L gasoline four-cylinder engine, the Trooper offered a choice of 4-speed manual or 4-speed automatic transmissions. Its off-road capabilities were enhanced by a two-speed transfer case for low-range gearing and a selectable 4WD system, allowing drivers to engage four-wheel drive on demand. The Trooper came in various body styles, including a two-door hardtop, a four-door wagon, and a two-door pickup truck, all sharing a classic boxy design that was typical of the era. The interior, though functional, was spartan in its appointments, reflecting the vehicle's focus on utility over luxury. Despite its robust nature, the Trooper received praise for its surprisingly comfortable ride and its ability to navigate challenging terrain. Despite its popularity and success, the first-generation Isuzu Trooper faced its share of challenges. The limited interior space and the lack of advanced safety features were common criticisms, and the aging engine technology was starting to show signs of being outmatched by the competition. However, the Trooper's reputation for reliability and its strong off-road performance ensured that it remained a popular choice for those seeking a rugged and capable vehicle. The WSM Service Manual, a comprehensive repair guide for the 1984-1991 Trooper, would have been an invaluable resource for owners and mechanics alike, providing detailed information on every aspect of the vehicle, from routine maintenance to complex repairs.
