TM 5-4210-220-34 2-21. FRONT AXLE - Continued 2-21.2 Differential Carrier - Continued (16)   Lift    out    spider    (18)    together    with    side pinions    (17),    and    thrust    washers    (16). Remove   inner   side   gear   (31)   and   thrust washer (14). (17)   Inspect inner and  outer  side  gears  and  the four   side   pinions.      Replace   all   gears   If excessively worn or damaged teeth, splines, or bearing surfaces are  noticed  on any of the gears. (18)   Discard all thrust washers, (16 and 14) and replace    with    new    components.        Inspect thrust washer bearing surfaces in differential case.  Replace both halves as a matched  set  if  any  surface  is  excessively worn. (19)   Inspect    differential    bearings    (9  and    22) as detailed in para.  2-7.  If replacement is required,        remove    bearing    cones    from differential case (20) and support cover (11) using   a   suitable   puller.      Replace   bearing cups and cones in pairs. NOTE Prior   to   reassembly   or   installation,   make   sure   all   components   are   clean   and   coated   with   a   film   of lubricating oil (item 17, Appendix B). (20)   If bearings are replaced, press new bearing cones (9 and 22) onto differential case (20) and support cover (11).  Be sure to use arbors that contact the bearing races only.  Bearings may be damaged if pressure is exerted on bearing roller cages. (21)   Install  thrust  washer  (14),  inner  side  gear  (31),  and  spider  (18)  complete  with  side  pinions  (17)  and  thrust washers (16) in support case (24). (22)   Install side gear (15), remaining thrust  washer  (14)  and  differential  case  (20).    Make  sure  punch  marks  on differential case and support case aline.  Install capscrews (21) and tighten to 180 ft lb (245 Nm). (23)   Check free rotation of differential by turning side  gear  hub.    Differential  may  require  up  to  50  ft  lb  (70  Nm) torque to rotate. NOTE Front differential ring gear is attached with eight 3/4 in.  16 capscrews and locknuts.  Rear differential ring gear IS attached with sixteen 5/8 in.  18 capscrews and locknuts. (24)   Install ring gear (12) on differential support case (24) making sure bolt holes aline.  A slight interference fit may be present between the parts.  If required, use a brass hammer to tap ring gear in place. 2-292
