AXLE VENT INSTALLATION
The High Flow Axle Vent is installed in the previously
drilled hole as shown in Figure 15. Refer to Axle
Preparation on page 13 for drilling details.

axle, ensure High Flow Axle Vent
is securely fastened and vent tube
points down.
WARNING: Failure to properly install axle

This could cause wheel-end failure
resulting in severe personal injury or
death.
