* Chrysler 8.25-inch: This was a very common rear axle for the 1996 Ram 1500.
* Dana 35: Less common than the 8.25, but possible, especially on lighter duty models.
* Dana 44: More common on heavier duty trucks or those with towing packages.
To know for sure which rear end is in *your* specific 1996 Dodge Ram 1500, you need to:
1. Check the Vehicle Identification Number (VIN) plate: The VIN contains information that can help determine the original specifications. A decoder website can help translate the VIN.
2. Look at the axle itself: The axle housing usually has casting numbers that identify the manufacturer and model. You'll need to get under the truck to see this. Take pictures if you're not familiar with identifying axle types.
3. Consult a parts catalog: Using your VIN, you can often look up the parts catalog online (e.g., from a dealer's website or a parts supplier like RockAuto).
Without more information about your specific truck, it's impossible to say definitively which rear end it has.
