If you use leaded fuel, you could damage your three-way catalytic converter
and other engine components.
Three- Way Catalytic Converter (diesel engines)
Your vehicle’s three-way catalytic converter is designed to reduce the
particulates in your vehicle’s exhaust. If your vehicle’s three-way catalytic

the
TBI throttle lever stud with engine oil. Do not oil any accelerator or
cruise control cables. Replace any cables that have high effort or excessive
wear.

three-way catalytic converter. Inspect the body near
the exhaust system.
Look for broken, damaged, missing or out-of-position parts,
as well as,
open seams, holes, loose connections or other conditions which could cause
a heat buildup
in the floor pan or could let exhaust fumes seep into the
passenger compartments.
Drive Axle Service? - Check readfront axle tluid level and add as needed,
Check constant velocity joints and axle seals for leaking.
Transfer Case (Four-wheel Drive) Inspection+ - Every 12 months or at
oil change intervals, check front axle and transfer case and add lubricant
when necessary. Oil the control lever pivot point and all exposed control
linkage. Check
vent hose at transfer case for kinks and proper installation.
