If the drive axle to be installed is a new part and
the vehicle is equipped with a speedometer, a cor-
rect size speedometer drive insert must be in-
stalled into the axle end. Ensure that insert is flush
with end of axle.
Position drive axle assembly into location. Install
end bearing housing. Install spacer (if applicable)
between bearing and lower chaincase sprocket.
Install chaincase and position seals (if applicable),
making sure that a gap of approximately 2 mm
(1/16 in) exists between end of bearing housing
and each seal.
