– Pull drive axle toward the end bearing housing
and take note of the measurement between
sprocket and tunnel.
The drive axle axial play is the difference between
these 2 measurements.
– Repeat this procedure 2 or 3 times to obtain an
accurate measurement.
The allowable drive axle axial play is 0 to 1.5 mm
(0 to .060 in).
The drive axle axial play, as calculated above,
should be within the allowable axial play, add
shim(s) accordingly.
– Remove drive axle, install required shim(s) as
per the shim position chart, reinstall drive axle
without the suspension and track.
