* Axle Type: Both the Bronco and F-150 used a variety of axle types in 1987-88. You need to identify the specific axle type in *both* vehicles. This typically involves looking up the axle codes (often stamped on the axle housing itself) or using a VIN decoder to determine the original specifications. Different axle types have different widths, spring perches, and mounting points.
* Wheelbase: The wheelbase of the Bronco and F-150 might differ slightly, impacting axle length compatibility. While they're similar trucks, a difference could mean the axles are too short or too long for the frame.
* Brake System: The brake systems might be different, requiring brake components to be swapped as well.
* Spring Perches: The location and style of the spring perches on the axles may not be directly compatible.
* U-bolts and other mounting hardware: Even if the axle housings fit, other hardware may need to be sourced.
In short, while it's *conceivable* that they could work with some modifications, it's not a simple direct swap. You'd need to meticulously compare axle specifications from both vehicles to determine compatibility. A mechanic specializing in older Ford trucks would be the best resource to assess the feasibility of this swap.
