1987-1990 Jeep Wrangler Cherokee Comanche Grand Wagoneer Parts Catalog

The 1987-1990 Jeep Wrangler Cherokee Comanche Grand Wagoneer Parts Catalog is an extensive illustrated reference for identifying components and matching part numbers across the Jeep vehicle range covered for the 1987 through 1990 model years. Its application information spans Wrangler YJ, Cherokee, Wagoneer, Comanche, Grand Wagoneer, J-10 and J-20, with individual illustrations and parts lists separated by model, body style, drivetrain, year and equipment where required.

At 1229 pages, this catalog goes far beyond a simple replacement-parts list. Exploded illustrations are paired with item numbers, part numbers, quantities, body and model references, descriptions and application notes. Many listings distinguish 1987-89 parts from 1990 changes, and the catalog also identifies differences such as two-wheel drive versus four-wheel drive, locking versus non-locking differentials, automatic versus manual transmission applications, U.S./Canada versus export equipment, ECE applications, diesel and gasoline engines, anti-lock brake equipment and other production variations.

Vehicle and Application Identification

A major strength of the 1987-1990 Jeep Wrangler Cherokee Comanche Grand Wagoneer Parts Catalog is the identification information provided before the illustrated groups. The opening pages explain catalog navigation, illustration numbering, part-number formatting, symbols and model application information. Vehicle identification material includes body I.D. plates, VIN information, model codes, date-code correlation tables, sales codes, engine identification, transmission identification, transfer-case identification and rear-axle identification.

The catalog identifies body styles including MJ – Comanche Pickup, SJ – Grand Wagoneer Wgn., J-10 & J-20 Pickups, XJ – Cherokee, Wagoneer Limited and YJ – Wrangler. Model codes shown in the catalog cover configurations such as Grand Wagoneer 4-door, J-10 pickups with 119-inch and 131-inch wheelbases, J-20 pickup, Comanche 2WD and 4WD with 6-foot and 7-foot boxes, Cherokee 2-door and 4-door 2WD/4WD versions, Wagoneer 4WD, and Wrangler 93-inch and 103-inch wheelbase applications. These references are especially useful when an illustration or part listing applies only to a particular body or configuration.

Illustrated Parts Identification

Throughout the catalog, component drawings are linked directly to numbered parts lists. The illustrations show assemblies broken into their service components, allowing a user to identify not only a major assembly but also related seals, bearings, retainers, shafts, brackets, fasteners, hoses, switches, gaskets, clips and other supporting parts. For many assemblies, the catalog separates right and left components and records year-specific or equipment-specific alternatives.

The axle sections, for example, contain separate material for Wrangler, Cherokee/Wagoneer/Comanche and Grand Wagoneer/J-10/J-20 applications. They distinguish front axle housings, disconnect and non-disconnect configurations, two-wheel-drive and four-wheel-drive parts, axle shafts, differentials and selective-drive locking hubs. Rear axle coverage includes Dana Model 35, Dana Model 44 and Dana Model 60 arrangements, including locking and non-locking differential versions and multiple axle ratios.

Engine-related catalog sections cover the 2.1L diesel, 2.5L, 4.0L, 4.2L and 5.9L engine applications shown in the publication. Depending on engine, the illustrated material includes identification, cylinder blocks, gasket sets, cylinder heads, crankshaft and piston components, camshaft and valve parts, engine mounting and associated systems. Fuel sections further differentiate carbureted, EFI and diesel applications and include fuel injection, pumps, filters, lines, tanks and related components.

Taken as a whole, this Jeep parts catalog is designed around precise component identification. It lets the user move from vehicle and body-code information to the relevant illustrated group, locate the component in an exploded drawing, and then cross-reference the numbered item to the corresponding part listing. The numerous year, drivetrain, engine, axle and market notes are particularly valuable where visually similar components have different applications or part numbers.

1987-1990 Parts Variations and Configuration Detail

The catalog repeatedly distinguishes production changes within its four-year coverage. Examples include separate 1987-89 and 1990 part numbers, build-date changes, 2WD and 4WD versions, different axle ratios and Dana axle types, standard-duty and heavy-duty suspension components, manual and automatic transmission equipment, anti-lock and non-anti-lock brake parts, and U.S., Canada, ECE, KDX and other export-market configurations. This level of differentiation makes the 1987-1990 Jeep Wrangler Cherokee Comanche Grand Wagoneer Parts Catalog useful when a vehicle cannot be identified accurately by model name alone.

It also documents numerous complete assemblies alongside their individual service components. Front and rear axles, brake assemblies, transmission and transfer-case systems, engine assemblies, steering columns, body hardware and electrical systems are illustrated in component form, making the catalog useful during disassembly, restoration planning, parts sourcing and comparison of replacement components. It is a parts-identification catalog rather than a step-by-step repair procedure manual, so its principal value is in showing component relationships, applications and cataloged part numbers.

Useful for Restoration, Repair and Parts Sourcing

For a 1987-1990 Jeep owner, restorer, workshop or parts supplier, this catalog can help identify exactly which component belongs to a specific vehicle configuration before parts are ordered or an assembly is taken apart. The exploded drawings can also help establish how groups of components fit together and which small retainers, seals, bearings, brackets or hardware pieces accompany a larger assembly.

The 1987-1990 Jeep Wrangler Cherokee Comanche Grand Wagoneer Parts Catalog is especially useful when working with vehicles that have accumulated decades of repairs, substitutions or missing components. Checking the cataloged body code, model application, year split, engine, transmission, axle and equipment notes provides a stronger basis for parts identification than relying on appearance alone.
