There is a code on the tag inside on the side of the door that will tell you what the rear axle has..

Ford Ranger Rear Axles - The Ranger Station

at the bottom is a list of the codes

 

There should be a tag on the diff. On bottom it will read 4 L 10. That is 4.10 limited slip. 4 10 this will be 4.10 open.

Not all explorer axles have limited slip. But i would suggest only an explorer axle for the swap. Ranger axles are 28 spline and drum brakes mostly. F-150 8.8's are wider and again drum brakes. Dont get earlier model explorer as they too are 28 spline and drum brake.

 

What years should I be looking for?

 

1995-2000 here is prob my fave write up and info site.
