Will a 2001 Dodge Ram 1500 9.25in rear axle fit 1998 1500?

While both are Dodge Ram 1500s and both use a 9.25" rear axle, a direct swap isn't guaranteed to be plug-and-play. There are subtle differences between model years, and even within the same year, depending on options (like ABS, limited slip differential, etc.).

Issues you might encounter:

* Brakes: The brake setups might be different. You might need to swap over brake components.

* Wiring: The ABS wiring, if present, will likely be different.

* Leaf Springs: The leaf spring perches might be slightly different, requiring modifications or using the springs from the 1998 truck.

* Shocks: The shock mounts might not align perfectly.

* Driveshaft: The driveshaft length might need to be adjusted or replaced.

In short: It *might* fit, but you should carefully compare the axles side-by-side before attempting the swap. You'll likely need to do some fabrication or component swapping to make it work properly and safely. It's best to find a 9.25" axle from a 1998-2001 Ram 1500 to avoid potential complications.
