* Dana: This is a very common supplier for heavy-duty axles in trucks like the Dodge 5500. Specific Dana models will vary widely.
* Meritor: Another major supplier of heavy-duty axles, likely used in some Dodge 5500 models. Again, the specific model will vary.
To know the *exact* type of axle on a specific Dodge 5500, you need to:
* Check the vehicle's build sheet or documentation: This is the most reliable method.
* Look at the axle itself: The axle housing usually has a manufacturer's tag or casting number that can be cross-referenced.
* Check the VIN: Using the VIN, you can sometimes find information on the vehicle's specifications through a vehicle history report or a dealer.
Without more specific information about the year and configuration of the Dodge 5500, it's impossible to pinpoint the exact axle type.
