Jeep Grand Cherokee 2004 Parts Catalog – OEM Factory Manual

If you have ever ordered a part for a Jeep Grand Cherokee 2004 Parts Catalog and ended up with the wrong piece because someone misread the VIN or guessed at the axle, then you understand why I keep this manual on the bench. This 2004 Parts Catalog is the factory source, not some aftermarket compilation thrown together from photocopies. It gives you the exact part numbers, illustrations, and codes straight from DaimlerChrysler. No guessing, no wasted trips to the dealer.

VIN plate decoding is where every job starts, and this manual makes it crystal clear. On page 1 you get the full table: position 2 is “J” for Jeep, position 5 tells you if it’s a Grand Cherokee 4×2 or 4×4, position 8 gets you the engine code – S for the 4.0L six, N for the 4.7L eight, J for the high-output 4.7L. That information alone saves you from ordering a radiator for the wrong engine (Group 7 has separate figures for 4.0L and 4.7L). If you’ve ever had a customer come back because the part didn’t fit, you know exactly what I mean.

VIN Plate Decoding: The First Step

Before you touch a wrench or pull a part number, you decode the VIN. The manual devotes page 1 to this – every position, every code. Country of origin, assembly plant (C for Jefferson, Y for STEYR), model year. For a 2004 Grand Cherokee the 10th position is “4”. Handy when you’re digging through salvage yards or cross-referencing used parts.

7 Groups of Factory Parts Data

This catalog is organized into seven groups, each covering a major system. Group 1 – Component Parts for Mopar Accessories – alone includes audio systems, bike carriers, ski racks, fog light packages, even a dog guard kit. Group 2 gets into front suspension and drive: control arms, stabilizer bars, axle shafts, differentials, and skid plates. Group 3 covers the rear axle with Dana 35 and Dana 44 housings and differentials. Group 4 handles the parking brake lever and cables. Group 5 is the full service brake system – calipers, rotors, master cylinder, hydraulic control unit, and lines. Group 7 deals with cooling (radiators, water pumps, drive belts). You get 433 pages of exploded diagrams and factory part numbers.

Front Suspension and Axle Parts

When a Grand Cherokee comes in with a clunk in the front end, you need to know which spring, control arm, or stabilizer bar matches the VIN. Group 2 gives you Figure 2-110 for suspension with springs and control arms, Figure 2-120 for the front stabilizer bar and track bar. Axle shafts, housing for 2WD and 4WD, axle assembly, differential – it’s all broken down. The skid plate package for the front axle is Figure 2-810. No more guessing which part fits which model year variation.

Does This Manual Cover the Brake System?

Yes, Group 5 runs from Figure 5-110 (front disc brake caliper and rotor) through Figure 5-610 (brake pedals, standard and adjustable). You also get the power brake booster, master cylinder, and the hydraulic control unit. Rear brake lines and chassis lines are separated from front lines – Figure 5-510 vs. 5-520. If you are swapping calipers or rebuilding the ABS module, this catalog gives you the correct part numbers without relying on a parts store computer that may have outdated info.

Get the Right Part Number the First Time

I have been wrenching for 28 years, and I have seen more comebacks caused by aftermarket catalogs with wrong supersessions than I care to count. This manual is a direct reprint of the OEM Jeep documentation – not a third-party knockoff. The part numbers match the factory build sheets. You want the cabin air filter kit? Figure 1-315. You need the navigation kit? Figure 1-140. You need to order a rear axle shaft for a Dana 44? Figure 3-410. It is all there, with the original Chrysler illustrations.

For related manuals, check the 2005 Jeep Grand Cherokee WK WH Factory Service Manual if you are working on the next model year, or the 1994-1996 Jeep Parts Catalog for older ZJ chassis. If you need coverage across multiple generations, the Jeep Wrangler Cherokee Grand Cherokee 1991-1993 Parts Catalog covers the earlier XJ and ZJ platforms.

For broader automotive context, Automotive Industry Overview provides background on how these vehicles were built, and Automotive Battery touches on the electrical systems you will see across the Grand Cherokee line.

That is what you get. A factory tool for ordering parts the right way.

How many pages does this manual have?

433 pages.

What does Group 1 cover?

Group 1 covers Component Parts for Mopar Accessories – audio electronics (10-disc player, satellite receiver, navigation kit), carriers and cargo hauling (bike carriers, canoe carriers, ski carriers, luggage carriers), driving convenience (cabin air filter kit), exterior protection (air shield, skid plates), fog lights and electrical (heater kit, fog light package), interior storage (dog guard kit), and security (EVS Plus alarm system). If you are adding factory accessories to a 2004 Grand Cherokee, this group gives you the exact part numbers and diagrams.

Is this manual specific to the 2004 Grand Cherokee?

Yes, it is the official 2004 model year parts catalog for the WJ Grand Cherokee. It includes VIN decoding for that year and covers all engine options (4.0L and 4.7L) and drivetrains (4×2 and 4×4).

Can I use it to identify parts for the 4.7L engine?

Yes. Engine codes are on page 1, and cooling system figures (Group 7) are separated for 4.7L engines.

If you want parts to land on the first order instead of the third, this is the document you need. Do not trust a Chilton or Haynes for part numbers – use the factory print. Access the Factory Manual now from AutoRepairManuals.
