Taken as a whole, the 2004 Jeep Wrangler TJ Mopar Parts Catalog is a lookup instrument rather than a how-to guide. Every page is built around an exploded illustration with numbered callouts on one side and a structured table on the other. Those tables are not just part numbers — they carry the series, body, engine, transmission and trim columns that tell you whether a given part actually fits your specific TJ. Sales codes such as [DME], [DMF], [DSA], [DSE], [BRW] and [BGA] are printed next to the entries they qualify, so a Rubicon, Sahara or Sport build can be isolated without guesswork, and the same is true for the two engines and the four transmission options available in 2004.

What Makes This Parts Book Useful in Practice

Parts catalogs of this type are the fastest way to settle a question that forums and generic parts listings get wrong. Because every assembly is broken into its component pieces, you can follow the chain from a visible symptom down to the exact fastener, seal, clip, bushing, bracket or bearing that needs replacing. That matters most on jobs where a single missing shim, an incorrect cover, or the wrong trim-code door handle stops the work.

The 2004 model year ran two engines (2.4L four-cylinder and 4.0L inline six), two manual transmissions, one four-speed automatic, two transfer cases and two rear axle families (Dana 35/194MM and Dana 44/226MM) with and without Trac-Lok or Trulok differentials. Because this catalog is laid out by group rather than by engine, the coverage is spread evenly across every one of those combinations, so there is no version of the 2004 TJ that is left out.

Where This 2004 Jeep Wrangler TJ Mopar Parts Catalog Helps Most

• Identifying a part before you order it — exploded diagrams show where the part sits and the table confirms whether it applies to your series, engine and transmission.
• Reassembly after a rebuild — axle, transfer case, transmission, engine and clutch groups are laid out as complete assemblies with all associated hardware.
• Restoration and trim work — seat trim codes, door trim panels, decals, mouldings, soft top and hard top components and sport bar pads are all indexed.
• Electrical diagnosis — sensors, modules, relays, switches, connectors, fuse blocks and the power distribution centre are all identified by part number and location.
• Body and frame repair — floor pans, crossmembers, body side panels, wheelhouse panels, hood, fenders, tailgate and body mount hardware are all covered separately.
• Upgrades and add-ons — the accessories group lists Mopar audio, cargo, protection, lighting, storage and security items by kit number.

How the Catalog Is Arranged

The document opens with the VIN decoding header used across the whole catalog — the series, line, body, engine and transmission codes that appear in the right-hand columns of every part table. Each group that follows begins with a group index page listing the illustration titles and their figure numbers, then proceeds to the illustration and table pages in that order. On most spreads you will find an exploded illustration on the left with numbered balloons, and on the right a table of item number, part number, quantity, line, series, body, engine, trans, trim and description. Notes on individual entries — warranty routing, whether a part is serviced only in an assembly, or whether it applies only to a specific sales code — are printed directly beneath the table headings where they belong.
