except the
TBI throttle shaft. Do not lubricate the cam pulley. Remove all
external deposits from pulley.
Do not oil any accelerator or cruise control
cables. Replace any cables that have high effort or excessive \
wear.
Exhaust System Inspection - Inspect the complete system. Inspect the
body near the exhaust system. Look for broken, damaged, missing
or
out-of-position parts, as well as open seams, holes, loose conn\
ections or
other conditions which could cause a heat buildup in the
floor pan or could
let exhaust fumes seep into the passenger compartments. See “Engine
Exhaust” in the Index.
Drive Axle Service - Check readfront axle fluid 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

ubricant
when necessary. Check vent hose at transfer case
for kinks and proper
installation. More frequent lubrication may be required on off-road use.
