The Jeep J20 Standard Cab Pickup, a product of the American Motors Corporation (AMC), was a heavy-duty pickup truck that carved its niche in the market from 1974 to 1987. Although sharing its name with the Jeep CJ-7, the J20 was a distinct vehicle built on a separate, heavier frame, designed to tackle demanding tasks. The 1979 J20, the focus of this manual, was a prime example of this robust character. It boasted a sturdy, all-steel, ladder frame chassis, a solid front axle, and a heavy-duty rear axle, providing a foundation for its impressive hauling and off-road capabilities. Power came from a variety of engines, including a 258 cubic inch (4.2L) inline-six or a 360 cubic inch (5.9L) V8, both mated to a four-speed manual transmission. The J20 was available in both 2WD and 4WD configurations, with the 4WD system featuring a Dana 20 transfer case. Its unique blend of strength, off-road prowess, and versatility made it a popular choice for farmers, ranchers, and construction workers. The 1979 J20 Standard Cab Pickup offered functional amenities and a simple, utilitarian design. The standard cab, while offering ample space for two, prioritized functionality over luxury. The interior was sparsely equipped, with vinyl upholstery, a basic dashboard, and minimal sound insulation. However, the J20 compensated for this with a durable and rugged build, designed to withstand tough working conditions. With its high ground clearance, heavy-duty suspension, and optional features like a PTO (power take-off) for driving implements, the J20 was a reliable partner for demanding tasks. The factory service repair manual, a vital tool for any J20 owner, provided detailed information on maintaining and repairing this robust machine, ensuring its continued operation and longevity. It served as a guide to keeping the J20 in optimal working order, allowing its owners to confidently tackle any challenge.
