Inspections
Listed in this part are inspections and services which
should be performed at least twice a year (for instance,

necessary repairs are completed at once.

found in a service manual. SeeService Publications
Ordering Information on page 7-11.

Drive Axle Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts, signs of
wear or lack of lubrication. Inspect the power steering
lines and hoses for proper hook-up, binding, leaks,
cracks, chang, etc. Clean and then inspect the drive
axle boot seals for damage, tears or leakage. Replace
seals if necessary.
Exhaust System Inspection

near the exhaust system. Look for broken, damaged,
missing or out-of-position parts as well as open seams,
