Should have checked on this sooner, but it sounds like it should change over just fine since i'm almost there, just have to finish the teardown of the explorer rear. It'll be great to find that the housings are the same and the gear just has to be changed out. The only problem i'm coming across is the tension spring in the center, how to remove it without screwing it up. Looks like an "S" pattern.PlumCrazy said:They will interchange. The only thing that makes an Expo 31 spline is the spider gears. The carrier from a 28 spline (Ranger/Mustang) is the same as the carrier from a 31 spline Expo. All 8.8's have the same pattern for gears (there is no carrier break). Swapping gears isnt a simple as just unbolting the old ones and bolting up the new ones. You need to make sure the backlash is set correctly and tooth contact is even and in spec (smear some connect grease on the teeth and rotate by hand adjust shims and pinion depth until pattern is perfect).
