Rear Wheel Alignment -- Inspection |
- NOTICE:
- For vehicles equipped with VSC, 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:
- Disconnect the cable from the negative (-) battery terminal for more than 2 seconds.
- Reconnect the cable to the negative (-) battery terminal.
- Perform zero point calibration of the yaw rate and acceleration sensor and test mode inspection.
| 1. INSPECT TIRES |
Check the tires for wear and proper inflation pressure.

kPa (kgf/cm2, psi)Rear
kPa (kgf/cm2, psi)P195/65R15 89S 210 (2.1, 30) 210 (2.1, 30) P205/55R16 89H

205/55R16 91V220 (2.2, 32) 220 (2.2, 32)
Using a dial indicator, check the runout of the tires.
- Maximum tire runout:
- 1.4 mm (0.0551 in.)

| 2. MEASURE VEHICLE HEIGHT |
 |
- NOTICE:
- Before inspecting the wheel alignment, adjust the vehicle height to the specified value.
- Be sure to perform measurement on a level surface.
- If it is necessary to go under the vehicle for measurement, confirm that the parking brake is applied and the vehicle is secured with chocks.
Bounce the vehicle up and down at the corners several times to stabilize the suspension.
Measure the vehicle height.
- Measuring points:
- A:
- No. 1 lower suspension arm bushing set bolt ground clearance
- B:
- Rear axle beam set bolt ground clearance
- C:
- Front wheel center ground clearance
- D:
- Rear wheel center ground clearance
- Vehicle Height (Unloaded Vehicle):
- Engine Tire Size Front C - A Rear D - B for TMC Made 2ZR-FE - 92 mm (3.62 in.) 45 mm (1.77 in.) except TMC Made 2ZR-FE 195/65R15 92 mm (3.62 in.)

| 3. INSPECT TOE-IN |
 |
- Toe-in (Unloaded Vehicle):
- Tire Size Specified Condition Right-Left Difference for TMC Made - C + D: 0°16' +/- 15' (0.27° +/- 0.25°) 45' (0.75°) or less B - A: 2.8 +/- 2.7 mm (0.110 +/- 0.106 in.) - except TMC Made 195/65R15
205/55R16C + D: 0°16' +/- 15' (0.27° +/- 0.25°)
C + D: 0°16' +/- 15' (0.27° +/- 0.25°)*1 *2
C + D: 0°16' +/- 15' (0.27° +/- 0.25°)*1 *345' (0.75°) or less B - A: 2.8 +/- 2.7 mm (0.110 +/- 0.106 in.)
B - A: 2.0 +/- 2.8 mm (0.0787 +/- 0.110 in.)*1 *2
B - A: 2.2 +/- 2.8 mm (0.0866 +/- 0.110 in.)*1 *3- 215/45R17 C + D: 0°16' +/- 15' (0.27° +/- 0.25°) 45' (0.75°) or less B - A: 3.1 +/- 2.6 mm (0.122 +/- 0.102 in.) -
*2 except XRS
*3 for XRS
If the toe-in is not within the specified range, inspect the suspension parts for damage and/or wear, and replace them if necessary.
- HINT:
- Measure "B - A" only when "C + D" cannot be measured.
| 4. INSPECT CAMBER |
Install a camber-caster-kingpin gauge or set the vehicle on a wheel alignment tester.
Inspect the camber.
- Camber (Unloaded Vehicle):
- Tire Size Camber Inclination Right-Left Difference for TMC Made - -1°28' +/- 30' (-1.47° +/- 0.50°) 30' (0.50°) or less except TMC Made 195/65R15 -1°27' +/- 30' (-1.45° +/- 0.50°) 205/55R16 -1°27' +/- 30' (-1.45° +/- 0.50°)
-1°26' +/- 30' (-1.43° +/- 0.50°)*1 *2
-1°27' +/- 30' (-1.45° +/- 0.50°)*1 *3215/45R17 -1°28' +/- 30' (-1.47° +/- 0.50°)
*2 except XRS
*3 for XRS- 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.
