Jeep Grand Cherokee 1998 Parts Catalog – 393 Pages of Factory Specs

I do not trust aftermarket parts catalogs. They skip figures, combine part numbers from different model years, and leave you holding a wrong control arm on a Saturday afternoon. The Jeep Grand Cherokee 1998 Parts Catalog from AutoRepairManuals is the real factory document — 393 pages, OEM release, scanned from the original 1998 binder. It covers the ZJ body with the 4.0L, 5.2L, and 5.9L engines. You get every part number for the front suspension, rear axle, brakes, cooling system, electrical components, and more.

Our shop uses this catalog when we order brake pads for a 1998 Limited or a front axle shaft for a 4×4 Laredo. The VIN decoding table on the opening pages lets you determine the exact engine and GVWR configuration so you order the right differential. No guessing. No cross-referencing three different websites.

Front Suspension & Rear Axle Coverage

Group 2 covers the front end completely: springs, shocks, control arms, stabilizer bar, track bar, axle shafts, and the front axle housing for both 2WD and 4WD models. The exploded figures show every bolt and bushing with an OEM part number. For the Dana 35 and Dana 44 rear axles, Group 3 provides separate housing and differential sections — including Trac-Lok and non-Trac-Lok versions. If you need the rear axle vent or shaft for a Dana 44, the part numbers are on the same page as the diagram.

Service Brakes and Parking Brake Parts

Group 4 covers the parking brake lever and cables. Group 5 breaks down the front and rear disc brakes, the power brake booster, master cylinder, the anti-lock hydraulic control unit, and every brake line from front to back. When you are replacing a seized brake hose on a 1998 Grand Cherokee, you want the exact OEM line part number — this catalog gives you Fig. 5-510 for front lines and Fig. 5-520 for rear lines. The pedal assembly illustration is also included.

7 Systems Covered – Cooling, Electrical, Engine Controls

Cooling system parts are split by engine: Group 7 covers the radiator, water pump, coolant tank, drive pulleys, drive belts, and transmission oil cooler lines for both the 4.0L and the 5.2L/5.9L engines. Grille parts are in there too. Group 8 handles starters, alternators, distributors, electronic modules, relays and fuses inside the power distribution center, sensors, the JTEC powertrain control module, switches, horns, battery tray and cables, and all exterior and interior lamps. The wiring section shows engine injector wiring and headlamp-to-dash harness routes.

VIN Decoding: Get the Right Parts from the Start

The opening pages include the factory VIN plate decoding chart. Position 5 tells you if you have a 4×2 or 4×4 Grand Cherokee. Position 8 gives the engine — S for 4.0L, Y for 5.2L, Z for 5.9L. Position 4 decodes the GVWR range. Use this to match the correct front axle housing and rear differential. That is the difference between ordering a part that fits and returning a box of wrong metal.

OEM Documentation vs. Aftermarket Catalogs

Aftermarket parts catalogs reprint a few pages and call it a day. They leave out the fine detail figures like the front axle differential internal parts (Fig. 2-610) or the rear axle vent (Fig. 3-310). This is the original Jeep document. Every part number was verified at the factory. You can cross-check it against the Automotive Industry Overview standards, but the real value is on your workbench when the part box arrives and the number matches the page.

Who Needs This Catalog

Home garage mechanics who rebuild their own brakes and suspension. Independent shop owners who want to quote the exact harness before tearing apart the dash. Owners of the 5.9L Limited who need the specific radiator from Fig. 7-160. Beginners who are learning how parts interact — the exploded view tells you what bolts to the control arm before the stabilizer bar. No guesswork.

Does this manual include the part numbers for the battery cables?

Yes. Fig. 8-1020 covers battery cables. The alternator mount and starter mount figures also appear in Group 8.

Can I use this catalog to order parts for a 1998 Grand Cherokee with the 5.9L engine?

Yes. The catalog covers the 4.0L, 5.2L, and 5.9L engines separately in the cooling system, electrical system, and engine wiring sections. Use the VIN decoding table on page 1 to confirm your engine code Z before ordering. If you pick the wrong engine figure, you get the wrong water pump or radiator. Check the VIN first — that is what the factory intended. The 5.9L engine has specific drive pulleys, water pump, and radiator parts that do not interchange with the 4.0L. The catalog gives you separate figures for each, so you do not waste a Saturday chasing the wrong part.
