TM 10-3930-671-24 Steer Axle Installation Installation   is   the   reverse   of   removal.      Also   refer   to removal procedures noted above. NOTE Make   sure   truck   is   correctly   raised and  safely   blocked   using   hardwood blocks  under  the  frame.    Be  sure  the blocking will permit installation of the axle without disturbing the blocking. NOTE Bushing  must  be  pressed  into  silent block  to  .322  in.    (0.2  mm)  minimum depth from end of casting. 1. If  silent  blocks  have  been  removed  from  axle, install   new   silent   block   assemblies   and   thrust washers  (or  spacers,  as  applicable,  depending on steer axle model).  See Section 9.5. 2. Make  sure  that  the  silent  blocks  are  positioned correctly    front    and    rear    on    the    steer    axle trunnions  at  the  start  of  installation.    Align  the silent blocks square with the axle. 3. Use   a   fork   lift   truck   or   mobile   floor   jack   to temporarily support and raise the axle into place under  the  truck.    If  another  lift  truck  is  used  to handle   axle,   center   the   forks   with   about   12 inches  spread  between  them.    Place  steer  axle assembly in secure position on fork tips. If   hydraulic   jack    is    used,    be    sure    axle    is    securely supported on jack pad. WARNING Heavy components can fall and cause severe  injury.    Keep  your  body  clear at all times. 4. Install axle assembly into frame by slowly raising it   up   while   guiding   silent   block   bushings   into frame sockets. F-428
