FINAL DRIVE DIAGNOSTICS
ALL WHEEL DRIVE (AWD) CONCERNS
All Wheel Drive (AWD) concerns are generally caused by a mechanical concern within the front gearcase, or electrical
concern. The following chart will help finding the root cause and assist with basic checks of the front gearcase and
AWD system. Refer to the proper chapter in the service manual for additional vehicle specific information.
SYMPTOM CAUSE
AWD stays engaged even when switch is OFF
• Rollers flat-spotted. Remove all and roll across a table
to check for flat spots
• Inside of ring gear is dimpled from harsh engagement.
Check the ramps and low spots inside ring gear.
Should be smooth
• Output Hub races are flat spotted/dimpled. Run your
finger along the outer surface that goes inside of the
cage. Should not feel and high points
• Armature plate or coil magnetized. Rule out armature
plate by putting it close to something metal to see if it
tries to stick.
• Drivetrain wedged. Often caused by torsion spring
coming out of place.
AWD Does not engage
• Roller cage is broken. Can typically find debris in the
oil if drained
• No power to AWD coil. Jump power and ground
directly to the coil and verify AWD function. If AWD
functions this confirms an electrical issue is causing
the concern. Verify fuses are in good condition and
inspect the wiring harness for damage or broken
wires. Check all connections for damaged pins or bad
connection.
• Weak magnetism. With power and ground to the coil,
armature plate should not be able to be pried off with
fingers.
• Armature plate bent/damaged. Check flatness and
look for uneven wear marks
• Prop shaft not turning at transmission snorkel shaft.
Internal transmission damage
