Rear differential information is needed.

[bountyhunterkc]

i am replacing the rear diff and axle in a 2003 for explorer 4x4 with the v-6 in it and was just wondering what rear assemblies are compatible?


any idea what stock gearing is in the ford?

 

[waskly]

any ex, with the same gearing from a 3rd gen.

you would need the same gear ratio. less its a 2x4 then w/e gear ratio you want from a 02-05 ex.

You can leave the front alone unless you are going to a different rear ratio. Look at the tag on your drivers door or on your diff to determine that. Then look for a rear diff with the same gear ratio and you'll be good to go!

[so i can install a 2001 or 2000 ford explorer rear axle assembly as long as its 3.55 geared corect(thats my gearing 3.55)

 

[bountyhunterkc]

so a 2001 ford explorer with 3.55 gears will fit?

 

[Ronin8002]

no, a 2001 won't work. it needs to be a 2002-2005 explorer (not sport trac).

Welcome to this forum! I've renamed your thread, and moved it into the transmissions, transfer cases, and differentials section.

Do you have a two door or four door?

If you have a 2003 Explorer Sport (2 Door), then yes you can use an axle from 2000 or 2001 Explorer with the same gear ratio.

If you have a 2003 Explorer 4 door, then no you cannot. You must use a 2002-2005 rear differential because the 3rd Generations have Independent rear suspension and not a solid axle.
