So are both front and rear axles D44??? Is the front and rear drum? Any chance the axles have the BOM numbers engraved on them from Dana/Spicer? If you are trying to go disc up front, it may be as simple as swapping the knuckles from a chevy/full size jeep (if bolt pattern is 6x5.5) or ford for 5x5.5 bolt pattern. Do you have any info on the axles (spline count, axles lengths for passenger/drivers side axles, and the complete axle assembly wheel mounting surface to wheel mounting surfac, etc...). As for the rear disc the Isuzu Rodeo and Honda Passport (suv) have a Dana 44 rear end with disc brakes already and have 6x5.5 bolt patern, and range from 58" to 63" WMS-WMS and some are set up for link or for leaf. Hope some of thisis helpful. Keep us posted with info on the axles :friday:
