IV.  STEERABLE DRIVE END DISASSEMBLY A. General Precautions for Disassembly IMPORTANT: READ THIS SECTION BEFORE STARTING THE DISASSEMBLY PR OCEDURES 1. Follow  each  procedure  closely  in  each  section, making use of both text and pictures. 2. The    outside    of    the    unit    should    be    carefully cleaned    before    starting    the    disassembly.        If steam   cleaning,   ensure   that   breather   and   air fittings    are    covered    to    prevent    water    from entering assembly. 3. Cleanliness - Provide a clean place to work.  It is important  that  no  dirt  or  foreign  material  enters the unit during repairs. 4. Refer to the Exploded Views located in the parts section as a guide to disassembly. 5. Assemblies  -  When  disassembling  the  various assemblies, lay all parts on a clean bench in the same  sequence  as  removed.    This  procedure will simplify reassembly and reduce the possibility of losing parts. 6. Bearings  -     Carefully   wash   and   relubricate   all bearings as removed and protectively wrap until ready   for   use.      Remove   bearings   with   pullers designed  for  this  purpose,  or  in  manner  which will   not   damage   those   bearings   that   will   be reused. 7. When  necessary  to  apply  a  force  to  remove  a part,    use    of    a    puller    or    press    would    be preferred.      However,    sometimes    it    may    be necessary to use a soft hammer or bar. B. Hub, Drum and Wheel Bearing Disassembly 1. Raise  the  front  of  the  vehicle  with  a  jack  and secure     vehicle     with     jackstands     of     suitable capacity. 2. Remove front wheels from vehicle. 3. Remove the brake drum.  (Disc wheel style hubs only). 4. With the end turned to full steering lock remove the   bolt   and   washer   retaining   the   outer   drive yoke.  (See fig.  14). 5. Remove the nuts from the outer axle shaft drive studs. 6. The flange should be loose enough to remove by hand.    If  not,  use  suitable  bolts  in  the  extractor holes  to  remove  the  outer  axle  shaft.    (See  fig. 15). Note: If oil is used for wheel bearing lubrication, care    should    be    exercised    to    protect    brake linings, etc. Fig.  14 Fig.  15 7. Remove the wheel bearing lock nut (See fig.  16) and   lockwasher   from   spindle.      Loosen   wheel bearing adjusting nut. 8. Rock    hub    lightly    to    loosen    the    outer    wheel bearing  cone.    Remove  the  cone  and  protect  it from  dirt.    If  wheel  bearings  are  oil  lubricated, some  oil  may  fall  on  the  brake  shoe  when  the hub is removed in the next step, unless suitable protection is used. -9-
