I have fron and rear axels from a 95 explorer 4x4. Im wondering if they will fit in my 94 4x4

 

Rear should be the same, not sure about the front.

 

Rear is basically the same ('95 used rear discs, right, so it will need some minor adjustment in adapting the brake system to the rear discs).

Front is very different. '94 used the TTB set up, '95 used a different IFS set up. I don't know how difficult it would be to adapt the '94 frame and the '95 IFS.
