What axle is in a 2004 Ram 3500?
Typically, the 2004 Ram 3500 uses a Dana 60 front axle and an American Axle Manufacturing (AAM) 11.5-inch rear axle. This setup is common on the heavy‑duty Ram 3500 models of that year, including both single-rear-wheel (SRW) and dual-rear-wheel (DRW) configurations. VIN and axle stamps can confirm the exact pairing on any given truck.
Front axle configuration
Before listing the specifications, note that the Ram 3500's front axle is designed for heavy‑duty service and torque from the Cummins diesel and other powertrains available that year.
- Axle type: Dana 60 solid front axle
- Position: Front axle housing rated for heavy‑duty use
- Typical gear ratio: Matched to model year and configuration (commonly around 3.54–4.10 in many heavy‑duty Rams)
Conclusion: The front axle for most 2004 Ram 3500 trucks is the Dana 60, chosen for durability and load capability.
Rear axle configuration
Before listing the rear‑axle details, note that the 3500's rear axle varies somewhat with wheel configuration but generally centers on a high‑strength unit designed to handle heavy loads and torque.
- Axle type: American Axle Manufacturing (AAM) 11.5-inch rear axle
- Wheel configuration: Suitable for SRW and DRW versions
- Common gear options: Various ratios were offered, typically in the range of 3.54–4.10 to support towing and highway efficiency
Conclusion: The rear axle is typically an AAM 11.5" unit, a robust pairing for the 2004 Ram 3500's heavy‑duty mission.
How to verify your exact axle
To confirm the exact axle on your vehicle, check the axle stamp on the differential cover or axle tag, or consult the build sheet/VIN decoding. The front should show D60 or equivalent, and the rear should show 11.5, 3.54, 4.10, etc., depending on the optioned ratio.
Summary
In summary, the 2004 Ram 3500 commonly pairs a Dana 60 front axle with an AAM 11.5" rear axle, a combination built for heavy‑duty work. Always verify with a VIN/build sheet or the axle tags on the vehicle for your exact configuration.

What year to stay away from Ram 3500?
You should avoid the 2003 and 2006 Dodge/Ram 3500 models due to specific issues like dashboard cracking in the 2003 and HVAC/suspension problems in the 2006. The 2013 Ram 3500 should also be approached with caution due to frequent recalls and known issues, particularly the "death wobble".
Years to avoid
- 2003: Known for a cracked dashboard and faulty Engine Control Module (ECM). It is also associated with higher-than-average repair costs.
- 2006: Has a reputation for suspension problems, including the "death wobble," and HVAC system faults.
- 2013: Has a high number of recalls and is particularly known for "death wobble" issues.
Potential issues to look for in other years
- First-generation models (pre-2003): Prone to rust, electrical problems, and unreliable speedometers/odometers.
- 2007-2018: While many consider the 6.7 Cummins in this range to be reliable, be aware of potential issues like the CP4 fuel pump failure that can occur in later models.
- 2023: Some owners have reported problems with fuel pumps and turbos.
General advice
- Always get a pre-purchase inspection from a mechanic who specializes in diesel trucks to check for common problems, especially in older models.
- When considering any used truck, check for maintenance records and ask the owner about any major repairs.
