Inspection and Replacement
All the components of your suspension system should be visually
inspected at least every 6,000 miles for signs of excess wear,
elongation of bolt holes, and loosening of fasteners. Whenever
loose or replaced, the fasteners in your suspension system
should be torqued as detailed in the charts below.
!
CAUTION
You must follow the maintenance procedures to prevent
damage to important structural components. Damage to
certain structural components such as wheel bearings
can cause the wheel to come off of the axle. Loss of a
wheel end while the trailer is moving can cause you to
lose control and lead to an accident, which can result in
serious injury or death.
