Unseen are two set screws at the 3 and 9 O’clock position usable to jack the case assembly out of the axle housing should it be stuck, and four of the five 7/16″ pinion support bolt holes are drilled and tapped blind to avoid sealing issues when a pinion support mounted skid plate is used.. The tail bearing uses a .812″ tall bearing adding capacity over others housings and is retained by a bolt in retainer plate.
