FASTENERS
When servicing a vehicle Hendrickson recommends replacing all removed fasteners
with new equivalent fasteners. Maintain correct torque values at all times. Check torque
values as specified. See Hendrickson's Torque Specifications Section of this publication.
If non-Hendrickson fasteners are used follow torque specifications listed in the vehicle
manufacturer's service manual.
When replacing components on the HN FR suspension, work one side of the vehicle at a time
and only lift the vehicle enough to remove load and component. This will help maintain axle
orientation and help reduce labor time.
