1999 Jeep Grand Cherokee Parts Catalog – OEM Part Numbers, Not Guessing

If you’ve ever ordered a brake caliper for a 1999 Jeep Grand Cherokee and ended up with the wrong casting, you already know why this Parts Catalog exists. I’ve seen guys pull a front axle shaft from a Quadra-Trac II donor and wonder why it won’t slide into a Select-Trac housing. The difference is in the VIN, the build month, and the option code. This 489-page factory document gives you the exact Mopar part numbers for every Group 1 accessory, Group 2 front suspension, Group 3 rear axle, Group 4 parking brake, Group 5 service brake, and Group 7 cooling component. Nothing from Haynes or Chilton will save you when the parts counter asks for the axle tube size or the differential case casting number. Only this catalog will.

VIN Decoding: The First Step in Ordering Parts

Page 1 of the catalog lays out the complete VIN plate decoding table. Position 5 tells you whether you’ve got a Grand Cherokee 4×2 left-hand drive (code 2), 4×2 right-hand drive (code 7), 4×4 right-hand drive (code 8), or 4×4 left-hand drive (code W). Position 8 decodes the engine: 4 for the 3.1L turbo diesel, N for the 4.7L V8, S for the 4.0L six, and V for the leaded-fuel 4.0L. I’ve seen a mechanic order a 4.0L radiator for a 4.7L because he didn’t decode the VIN first. That mistake costs a Saturday. This catalog gives you the engine code, the series (Laredo vs. Limited), and the assembly plant (Jefferson or STEYR). Cross-check your VIN against the table before you buy anything.

Group 1 – Mopar Accessories: Audio, Carriers, and Off-Road Gear

The Group 1 section covers every authorized Mopar accessory for the 1999 WJ. Audio & Electronics (Fig. 1-110 and 1-115 for FM-modulated player kits, plus player kits), Carriers & Cargo Hauling (basket-type, multipurpose, canoe, water sports, bike roof mounts, fold-down bike mounts, lockable bike mounts, ski carriers, trailer tow wiring, interior storage box, power steering cooler), Driving Convenience (cellular phone mounting kit, cabin air filter kit), Exterior Appearance (running boards, side step kit), Exterior Protection (air front shield kit, skid plate package), Fog Lights & Electrical (heater kit, fog light package), Security (security alarm module), and 4-Wheeling & Off Road (rock rail guards, brush/grille guard). Each figure includes an exploded diagram with Mopar part numbers. If you need to add a factory roof basket, you can order the correct carrier kit (Fig. 1-210) and know the bolt pattern fits the WJ crossbars. No aftermarket vendor gives you that level of detail for a 20-year-old model.

3 Drivetrain Groups – Axles, Suspension, and Brakes

Groups 2, 3, 4, and 5 cover everything below the body. Front suspension (Group 2) includes springs, control arms, stabilizer bar, track bar, front axle drive shafts, front axle housing for 2WD and 4WD, the front axle assembly, the front axle differential, and the front axle skid plate. Rear axle (Group 3) splits into Dana 35C/194MM and Dana 44/226MM housings, with differentials for Trac-Lok and Vari-Lok progressive designs. Parking brake (Group 4) covers the lever, cables, and rear disc parking brake assembly. Service brakes (Group 5) give you front calipers for Continental Teves and Akebono, rear disc calipers, power brake booster, master cylinder, hydraulic control unit, and complete brake line diagrams (right front, left front and chassis, front hose, rear lines). Brake pedal and bracket are also shown. I’ve used this catalog to confirm the rear axle housing gasket part number for a Dana 44 – the aftermarket suppliers list a generic gasket that leaks. The factory illustration tells you the exact vent tube and breather location, which matters when you’re swapping axles on a lifted Jeep.

Why OEM Part Numbers Beat Aftermarket Cross-References

Aftermarket catalogs from parts stores often lump the 4.0L and 4.7L cooling systems into one drawing. This catalog has separate radiator illustrations (Fig. 7-150 for 4.0L, Fig. 7-160 for 4.7L, Fig. 7-165 for the 3.1L diesel). The water pump and related parts also split by engine (Fig. 7-210 for 4.0L, Fig. 7-220 for 4.7L). If you order a 4.0L water pump for a 4.7L, the pulley offset is wrong and the belt won’t track. That’s a $90 mistake. The factory part numbers in this catalog tie directly to the Mopar system – you can hand the number to the dealer counter or cross-reference it with online OEM suppliers. The VIN decoding table at the front is the key. Use it before you open a wrench.

Does This Parts Catalog Cover Your Grand Cherokee?

This catalog is for the 1999 model year WJ Grand Cherokee. If you’re working on a 2000 or later WJ, some part numbers changed, especially for axles and interior components. You’ll want a year-specific catalog or a supplement. For 1999, this is the only factory document that lists every component from the Mopar accessories line to the cooling system. The 489 pages include figure numbers, exploded views, and part number tables. You can also find related manuals like 2005 Jeep Grand Cherokee WK WH Factory Service Manual”> or older models like 1994-1996 Jeep Parts Catalog”> and the Jeep Wrangler Cherokee Grand Cherokee 1991-1993 Parts Catalog”> for cross-referencing. For general automotive knowledge, check Automotive Industry Overview”> and understanding Automotive Battery”> specs for your Jeep.

Consistency Across Vehicle Families (WJ)

The catalog uses the WJ platform code throughout. All figure numbers reference the 1999 WJ index. Every Group has a consistent numbering system – for example, Fig. 5-110 is the front disc brake caliper (Continental Teves) and rotor. Fig. 5-120 is the same location for Akebono calipers. You won’t find a single page where the drawing jumps between model years. Jeep produced this catalog for the 1999 model year only, so the part numbers are locked to that production window. If you need to know the difference between a Dana 35C axle housing (Fig. 3-210) and a Dana 44 housing (Fig. 3-220), the illustrations show the vent tube placement, cover bolt count, and tube diameter. That information is not in any universal aftermarket catalog.

FAQ

Is this catalog useful for a 1999 Jeep Grand Cherokee with the 4.0L engine?

Yes. The VIN decoding table on page 1 tells you if you have the ERH 4.0L (code S) or the leaded version (code V). Then you reference engine-specific figures like 7-150 for the radiator.

Does this include service procedures or only parts numbers?

Only parts numbers and exploded diagrams. For torque specs and repair steps, you need the factory service manual. This catalog complements a service manual but does not replace it. I keep both on my bench.

How do I decode the axle type from the catalog?

Check the VIN position 8 for engine, then look at Group 3. The catalog splits Dana 35C and Dana 44 housings by figure numbers. The differential sections also separate Trac-Lok and Vari-Lok options. Cross-reference your axle tube stamping with the illustration.

Can I use this for a 1998 Grand Cherokee?

The 1998 ZJ has different part numbers for most drivetrain components. This catalog is specific to the 1999 WJ. Order the correct year catalog to avoid mismatched brackets and axle spacers.

Your time is worth more than ordering the wrong part twice. This factory Jeep Grand Cherokee Parts Catalog gives you the exact Mopar numbers for every nut, bolt, bracket, and assembly on the 1999 WJ.
