REAR AXLE DIAGNOSIS
REAR AXLE27-3
SYMPTOM PROCEDURESM1271004400222
INSPECTION PROCEDURE 1: Abnormal Noise
DIAGNOSIS
STEP 1. Check the rear hub assembly installation bolts for
looseness.
Q: Are the rear hub assembly installation bolts loosened?
YES : Tighten the rear hub assembly installation bolts to the
specified torque 73
7 Nm (54 5 ft-lb). Then go to
St e p 4 .
NO : Go to Step 2.
STEP 2. Check the wheel bearing end play.
(1) Remove the caliper assembly, and suspend the caliper
assembly with a wire and remove the brake disc.
(2) Check the bearing's end play. Place a dial gauge against
the hub surface; then move the hub in the axial direction
and check whether or not there is end play.
Limit: 0.05 mm (0.002 inch)
Q: Is the wheel bearing end play within the limit?
YES : Go to Step 3.
NO : Replace the rear hub assembly, then go to Step 4.
STEP 3. Check the rear hub rotary-sliding resistance.
(1) Remove the caliper assembly, and suspend the caliper
assembly with a wire and remove the brake disc.
(2) Turn the hub a few times to seat the bearing.
(3) Wind a rope around the hub bolt and turn the hub by pulling
at a 90
angle with a spring balance. Measure to determine
whether or not the rotary-sliding resistance of the rear hub
is within the limit value.
Limit: 24 N (5.4 lbs)
Q: Is the rear hub rotary-sliding resistance within the limit?
YES : Go to Step 4.
NO : Replace the rear hub assembly, then go to Step 4 .
STEP 4. Retest the systems.
Q: Are abnormal noises generated?
YES : Return to Step 1.
NO : The procedure is complete.

REAR HUB ROTARY-SLIDING RESISTANCE
CHECK
M1271001100266
1. Remove the caliper assembly, and suspend the caliper
assembly with a wire and remove the brake disc.
2. Turn the hub a few times to seat the bearing.
3. Wind a rope around the hub bolt and turn the hub by pulling
at a 90 degree angle with a spring balance. Measure to
determine whether or not the rotary-sliding resistance of the
rear hub is within the limit value.
Limit: 24 N (5.4 pounds)
4. If the rotary
sliding resistance exceeds the limit value,
replace the rear hub assembly.
5. After having finished the inspection, install the brake disc,
caliper assembly and tighten the caliper assembly mounting
bolts to the specified torque.
Tightening torque: 60
5 Nm (45 3 ft-lb)
