cable guides, propshaft splines, universal joints, brake pedal springs,
and clutch pedal springs at the intervals specified on the proper
maintenance schedule, or at every engine oil change, whichever comes
first
.
Ball joints should not be lubricated unless their temperature is 10°F
(-12°C) or higher. When the weather is cold, let them warm up before

Downloaded from www.Manualslib.com manuals search engine Periodic Maintenance Inspections
Listed below are inspections and services which should be perfo\
rmed at
least twice a year (for instance, each spring and fall). You should let your
GM dealer’s service department or other qualified service center do these
jobs. Make sure any necessary repairs are completed
at once.
Steering and Suspension Inspection? - Inspect front and rear suspension
and steering system for damaged, loose or missing parts, signs of wear or
lack of lubrication. Inspect power steering lines and hoses for proper
hook-up, binding, leaks, cracks, chafing, etc.
Lu‘ ~ kate the steering linkage.
Accelerator Control System - Lubricate all pivot points with engine oil,
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
oil change intervals, check front axle and transfer case and add l\
ubricant
when necessary. Check vent hose at transfer case
for kinks and proper
installation. More frequent lubrication may be required on off-road use.
