Periodic Maintenance Inspections - GMC 1994 Sonoma Owner's Manual

Periodic Maintenance Inspections
Listed below are inspections and services which should be performed 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. Lubricate 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 connections 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) Inspectionj*
-
Every 12 months or at
oil change intervals, check front axle and transfer case and add lubricant
when necessary. Check vent hose at transfer case for kinks and proper
installation. More frequent lubrication may be required on off-road use.
?A fluid loss in these systems may indicate a problem. Have them inspected
and repaired at once.
