DISMANTLE 
It is important  that  when  dismantling  the  differential 
the relationship  of the  components  are marked 
relative 
to each  other  and to their position  in  the 
pinion  housing  and differential  carrier 
so that if 
refitted, the original  settings  are  maintained to avoid 
the  possibility  of noise  and  premature  wear of the 
overhauled 
axle. In particular bearing caps  and gears 
must  not be interchanged  and new  gears  should 
never  be matched...

is  possible,  however, to drift-off  the  bearing 
from the  gear  housing side of the  carrier  by 
positioning  a drift  in the
