Verify axle identification before ordering, since this kit is specific to Dana/Spicer 80 rear axle applications and includes fitment variations for certain 1998 Ford E-350 models with 4.375 in. or 4.125 in. pinion bearing configurations. Inspect the differential, bearings, races, and seals during teardown so the replacement parts match the axle setup exactly. Professional installation and proper setup procedures are recommended for differential service.
