Rear Wheel Alignment
ALIGNMENT / HANDLING DIAGNOSIS: REAR WHEEL ALIGNMENT: ADJUSTMENT
The content of this article/image reflects the changes identified in TSB L-SB-0069-12 dated august 29, 2012.
NOTICE:
If the wheel alignment has been adjusted, and if suspension or underbody components have been removed/installed or replaced, be sure to perform the following initialization procedure in order for the system to function normally:
* Perform zero point calibration of the yaw rate and acceleration sensor.
1. INSPECT TIRES Component Tests and General Diagnostics
2. MEASURE VEHICLE HEIGHT Front Wheel Alignment
3. INSPECT CAMBER
NOTICE:
Inspect while the vehicle is unloaded.
(a) Install a camber-caster-kingpin gauge.
Text in Illustration
(b) Inspect the camber.
Camber (Unloaded Vehicle):
HINT
Camber is not adjustable. If the measurement is not within the specified range, inspect the suspension parts for damage and/or wear, and replace them if necessary.
4. INSPECT TOE-IN
NOTICE:
Inspect while the vehicle is unloaded.
(a) Bounce the vehicle up and down at the corners to stabilize the suspension.
(b) Release the parking brake and move the shift lever to N.
(c) Push the vehicle straight ahead approximately 5 m (16.4 ft.). (Step A)
(d) Put tread center marks on the rearmost points of the rear wheels and measure the distance between the marks (dimension B).
Text in Illustration
(e) Slowly push the vehicle straight ahead to cause the rear wheels to rotate 180° using the rear tire valve as a reference point.
HINT
Do not allow the wheels to rotate more than 180°. If the wheels rotate more than 180°, perform the procedure from Step A again.
(f) Measure the distance between the tread center marks on the front side of the rear wheels (dimension A).

Toe-in (Unloaded Vehicle):
HINT
Measure "B - A" only when "C + D" cannot be measured.
(g) If the toe-in is not within the specified range, adjust it at the rear No. 1 suspension arms.
5. ADJUST TOE-IN
(a) Inspect the rear No. 1 suspension arm assembly.
(1) Inspect the nuts and adjusting tube for looseness visually and by hand. (Step B)
Text in Illustration
(2) Put matchmarks onto the rear No. 1 suspension arm assembly as shown in the illustration below.
Text in Illustration
(3) Using the SST, try turning the adjusting tube in both clockwise and counterclockwise directions with the specified torque to check that the matchmarks will not be misaligned.
WARNING
Do NOT apply more force than specified when checking for adjusting tube or jam nut looseness.
SST: 09617-24011
Torque:
Without SST: 20 N*m (204 kgf*cm, 15 ft*lbf)
Torque:
With SST: 17 N*m (174 kgf*cm, 13 ft*lbf)
Use a torque wrench with a fulcrum length of 300 mm (11.8 in.)
(4) Check the lock nut at the ball joint side for looseness.
Holding the adjusting tube and using the SST, turn the lock nut at the ball joint side in both clockwise and counterclockwise directions with the specified torque to check that the matchmarks will not be misaligned.
WARNING
The wrench applied to the adjusting tube should NOT be turned during this step. HOLD the wrench applied to the adjusting tube while applying force to the SST or torque wrench. If the lock nut is found loose, replace the tie rod assembly.
Torque:
Without SST: 20 N*m (204 kgf*cm, 15 ft*lbf)
Torque:
With SST: 17 N*m (174 kgf*cm, 13 ft*lbf)
Use a torque wrench with a fulcrum length of 300 mm (11.8 in.)
(b) Measure the length of the left and right rear No. 1 suspension arm assemblies.
Standard difference:
1.0 mm (0.0394 in.) or less
(c) Loosen the 2 nuts of the adjusting tube.
NOTICE:
If either nut is abnormally tight when loosening it (90 N*m (918 kgf*cm, 66 ft.*lbf) or more), or if either nut does not rotate smoothly by hand after loosening it, replace the rear No. 1 suspension arm assembly.
HINT
Loosen the 2 nuts of the adjusting tube on the other side using the same procedure.
(d) If the difference between the length of the left and right rear No. 1 suspension arm assemblies is not within the specification, adjust the value to within the specification using the method below.
(1) If the toe-in value deviates towards the inside, turn the adjusting tube of the shorter rear No. 1 suspension arm assembly in the direction which increases arm length until the difference between the left and right suspension arms is within the specification.
(2) If the toe-in value deviates towards the outside, turn the adjusting tube of the longer rear No. 1 suspension arm assembly in the direction which decreases arm length until the difference between the left and right suspension arms is within the specification.
(3) Measure the toe-in again.
(e) Turn the left and right adjusting tubes in the same direction by the same amount to adjust the toe-in.
Toe-in (Unloaded Vehicle):
HINT
* When the adjusting tube of the rear No. 1 suspension arm assembly LH is turned one revolution in the direction of A in the illustration, the toe-in changes to the inside by approximately 8.8 mm (0.346 in.).
* When the adjusting tube of the rear No. 1 suspension arm assembly LH is turned one revolution in the direction of B in the illustration, the toe-in changes to the outside by approximately 8.8 mm (0.346 in.).
(f) Attach a string and weight to the vehicle as shown in the illustration.
(g) Place the vehicle on a level surface, and then check that the string and weight are perpendicular to the vehicle body.
1. Tighten the inboard (bushing side) lock nut.
Torque:
Without SST: 56 N*m (571 kgf*cm, 41 ft*lbf)
Torque:
With SST: 49 N*m (500 kgf*cm, 36 ft*lbf)
WARNING
The wrench applied to the adjusting tube should NOT be turned during this step. HOLD the wrench applied to the adjusting tube while applying force to the SST or torque wrench.
2. Tighten the outboard (ball joint side) lock nut.
Torque:
Without SST: 56 N*m (571 kgf*cm, 41 ft*lbf)
Torque:
With SST: 49 N*m (500 kgf*cm, 36 ft*lbf)
3. Tighten the inboard (bushing side) lock nut again.
Torque:
Without SST: 56 N*m (571 kgf*cm, 41 ft*lbf)
Torque:
With SST: 49 N*m (500 kgf*cm, 36 ft*lbf)
WARNING
Failure to follow this procedure will result in the lock nut not being tightened to the proper torque and/or becoming loose.
(m) Check that the ball joint socket is parallel to the string.
Text in Illustration
NOTICE:
If the ball joint socket is at an angle of 5° or more with respect to the string, perform steps F to J again.
(n) Remove the string and weight from the vehicle.
6. PLACE FRONT WHEELS FACING STRAIGHT AHEAD
7. PERFORM YAW RATE AND ACCELERATION SENSOR CALIBRATION
