Hi Everyone,

I have a 98 Dakota 4x4 donor truck that has a 5.2L and 3.92 differentials. I would like to swap both axle housings from the 98 to my 2000 Dakota crewcab 4x4 that currently has a 4.7L and 3.55 gears. I noticed on a salvage yard sight that when comparing rear differentials they seem to interchange the 97 through 99 models and then jump to 2000 through 2002 models. Did something change in 2000? Both rear axles are 10 bolt 8.25" with drum brakes. The front axle assembly seems to be interchangable through all of the year models as long as you know your ABS setup. Then of course, I'll have to have my computer flashed for the new gear ratio's Any suggestions or concerns about this swap are appreciated. Thanks.
