Daimlerchrysler Durango Technical Manual: Factory Parts, VIN Decoding & Assembly Diagrams

You pulled the VIN off a 2001 Durango and need to know if it’s a 4×2 or 4×4, or what engine it left the factory with. You’ve got a parts diagram that shows a ‘Fig. 2-110’ for the front suspension but you can’t tell if it applies to your DN1 or DN5 chassis. That’s where this Daimlerchrysler Durango Technical Manual saves your bacon. 421 pages of pure factory documentation — not a third-party reprint, not a scanned photocopy. This is the same binder the dealer parts counter uses. Every figure number, every part reference, every VIN position is taken straight from the original Daimlerchrysler engineering files.

No aftermarket junk here.

VIN Plate Decoding: The First Step in Any Repair

Open to page 1 and you get a full VIN decoding table that breaks down each of the 17 positions. Need to verify if that Durango is a 4×2 (line code R) or 4×4 (S)? Engine code N for 4.7L or Z for 5.9L? Model year from W (1998) through 3 (2003)? It’s all there. I’ve seen guys order an entire front axle assembly for the wrong GVWR class because they skipped this step. This manual eliminates that guesswork. The table on page 1 gives you country, make, vehicle type, GVWR range, series, body style, engine, check digit, assembly plant, and sequence number. That’s the kind of detail you need before you pick up a wrench.

Front Suspension & Drive: DN1 vs DN5 Differences

Group 2 covers front suspension and drive components with separate figures for the DN (standard) and DN5 (heavy-duty) chassis. Fig. 2-110 shows control arms, springs, shocks, knuckle for DN; Fig. 2-130 covers the DN5 variant. Each figure lists the individual part numbers for bushings, ball joints, and mounting hardware. If you’re rebuilding the front end on a 2002 Durango R/T, you need the DN5 torsion bar and stabilizer bar details from Fig. 2-140. The manual also includes front axle drive shafts, housing, differential, and even the skid plate assembly. Pair this with a factory service manual for torque specs and you’ve got a complete repair plan.

Rear Axle: Corporate 8.25 vs 9.25

Two different rear axle assemblies: the Corporate 8.25 (DRA) and the Corporate 9.25LD (DRB). This manual identifies which axle your Durango left the factory with by the VIN and then gives you the exploded diagrams for differential carriers, housings, and the axle vent (Fig. 3-310). Fig. 3-110 and 3-120 break down both assemblies. If you’re swapping gears or replacing an axle shaft, you need to know which carrier group you have. The part numbers are listed by figure, so you can order exactly what fits. No more returning the wrong bearing kit three times.

Service Brakes: Front and Rear Disc Procedures

Group 5 covers the entire brake system: front brakes (Fig. 5-110), rear disc brakes (Fig. 5-210), power brake booster (Fig. 5-310), master cylinder (Fig. 5-410), and all the lines and hoses from the EHCU or RWAL II module to the frame and chassis. The brake lines are broken out by DN1/DN5 and RWAL/AWAL systems. If you’re replacing a rusty brake line on a 1999 Durango with RWAL, you’ll need the specific routing from Fig. 5-520. This manual doesn’t give you the bleeding procedure or torque values — get the factory service manual for that — but it gives you every bracket, clip, and line part number so you can assemble the system correctly.

Cooling System: 4.7L vs 5.9L Engine Differences

Group 7 splits cooling components by engine. Fig. 7-110 covers the radiator and related parts for the 4.7L; Fig. 7-120 for the 5.9L. Water pumps, drive pulleys, belts, and transmission oil cooler lines are all separated by engine and transmission type (multi-speed vs 4-speed). If you’re swapping in a 5.9L into a truck that came with a 4.7L, you’ll need the correct pulley configuration (Fig. 7-410) and coolant tank (Fig. 7-305). The manual also includes the oil cooler line routing for both transmission options — a detail that aftermarket diagrams always blur over.

Mopar Accessories: What Original Equipment Looks Like

Group 1 lists every Mopar accessory from audio (CD changer, navigation, rear seat video) to carriers (bike, ski, canoe), exterior protection (brush guards, grille guards), fog lights, and skid plates. Each accessory has its own figure number with complete parts breakdown. For example, the wiring kit for trailer tow is Fig. 1-292; the EVS II security alarm is Fig. 1-910. If you’re adding factory accessories to a Durango that didn’t come with them, this manual shows you exactly which mounting kits, wiring harnesses, and hardware you need. You won’t be drilling holes blind.

One thing I appreciate about this Daimlerchrysler Durango Technical Manual: it references genuine OEM part numbers directly. You can cross-check with your local dealer or an online parts catalog. For more on factory documentation standards, see Automotive Industry Overview. That page explains why Daimlerchrysler used this numbering system.

If you’re working on multiple Durango years, check out these related manuals: DaimlerChrysler Durango VIN Decoding Technical Manual, DaimlerChrysler Durango 2000 VIN Decoding Technical Manual, and DaimlerChrysler Durango VIN Plate Decoding Manual. Each one covers a specific model year range and provides the same factory-level detail. Another good reference is Automotive Industry Overview for understanding how OEM documentation differs from aftermarket reprints.

What can I get out of this manual that a Haynes or Chilton doesn’t have?

Factory part numbers and exact figure references for every component. A Chilton might show a generic brake line diagram; this manual shows the exact routing from the EHCU to the frame for your specific Durango model (DN1 vs DN5, RWAL vs AWAL). It also has the VIN decoding table on page 1 that tells you which engine, axle, and GVWR your truck left the factory with. That information is critical when ordering replacement parts.

Does this manual include torque specifications?

No. This is a parts and assembly reference, not a repair procedure manual. You still need the factory service manual for torque specs and removal sequences.

This manual sits on my bench next to the factory service manual. I use it to confirm part numbers, decode VINs before ordering, and check which figure applies to the specific chassis I’m working on.
