Inspection Procedure 10

DIAGNOSIS

NOTE: In addition to a malfunction of the differential carrier components, abnormal noise can also be caused by the universal joint of the propeller shaft, the axle shafts, the wheel bearings, etc. Before disassembling any parts, take all possibilities into consideration and confirm the source of the noise.

STEP 1. Check the drive gear backlash (excessive).
If faulty, adjust it. Then go to Step 3.
If normal, go to Step 2.

STEP 2. Check for looseness in the companion flange tightening nut.
If loose, tighten to 216 Nm (159 ft. lbs.). Then go to Step 3.

STEP 3. Check symptoms.
Check that no noise is generated.
