Steering Gear Lubrication
Inspection
NOTE: Before removing reservoir cover, wipe out-
side of cover so that no dirt can fall into the reser-
voir.
1. Check the
fl
uid level; add
fl
uid if required.
2. Check
fl
uid for contamination, discoloration, or burnt
smell; correct source of such problems before replac-
ing
fl
uid &
fi
lter.
CAUTION: When adding
fl
uid, be sure to use
fl
uid of the same type. While many
fl
uids have
the same description and intended purpose,
they should not be mixed due to incompatible
additives.
• If incompatible (insoluble)
fl
uids are
mixed in a power steering system, air
bubbles can be produced at the inter-
face of the two
fl
uids. This can cause
cavitation, which reduces the lubrication
between moving parts in the gear. This
could result in worn components.
• The mixture of two different
fl
uids, al-
though harmless to individual internal
components, may initiate a chemical
reaction that produces a new compound
that will attack seals and other internal
components.
• Do not mix different
fl
uids.
Universal Joint Lubrication
Refer to the Spicer Universal Joints and Driveshafts service
manual and lubrication speci
fi
cations.
Replacement
1. Replace both
fl
uid and
fi
lter as per the chart below.
2. Bleed the system if necessary
