LUBRICATION GUIDE
Check and lubricate all components at the intervals outlined in the Periodic
Maintenance Chart. Items not listed in the chart should be lubricated at the
General Lubrication interval.
The a-arms and upper control arms are lubricated at the factory, and no
additional lubrication will be needed. However, if these components are
subjected to severe use, grease zerks have been provided for additional
lubrication at the user's discretion.
