DANGER

Read and Understand the installation, service and safety  instructions manual before installing or
servicing the hub. Failure to do so may result in personal injury or death, and may result in a 
compromise of your vehicle’s safety through loss or failure of a wheel or compromise of the braking 
system.

Use a torque wrench to assure proper torque, failure to do so will compromise your products service,
life and safety. Under torque and over torque can cause thread and/or nut damage, and may result in
the loss of a wheel.

Recheck torque after the first 50 to 100 miles of service. Parts may seat naturally, causing the torque
to drop. Proper torque is essential for the service, life and safety of this product.
