For some reason I thought that only FX4's came with 8.8 rear ends, but I decided to cheak my axle code earlier, and found out that my truck has a open 8.8 with 4.10's. Just didn't realize that ford put 8.8 axles under edge models. I guess you really do learn something new every day.

 

Hell yeah bud, I have an 8.8 in mine, with 3.55 L/S.

 

I believe that all 4.0s and 3.0 4X4s have the 8.8 rear end.

 

^^^ I think you are correct (at least in the newer ones)

 

4.0's and 4x4's get the 8.8 axle. Others are 7.5 except:

All Edges got the 8.8 from sometime in 2002 through 2005, regardless of engine and drive.
2006/7 Sports (the renamed Edge) continue to use it too.
The 2000 Trailhead had the 3.0L and 8.8.

2002 FX4's and 2003+ Level II's also have an 8.8 axle assembly but it is a heavier duty version with larger axle shafts, axle tubes and bearings. It comes with a Torsen L/S.

There may be differences for earlier Rangers but the above should be accurate for at least the last 15 years.

 

Thanks Bob!!!
