Rear Wheel Alignment: Adjustment

WARNING: This page is about a different car, the 2006 Scion tC. However, it is still accessible from the selected car via links, so may be relevant.

INSPECT TIRE
1. Inspect the tire (See INSPECTION ).
MEASURE VEHICLE HEIGHT
1. Measure the vehicle height (see ADJUSTMENT ).

INSPECT TOE-IN

Standard toe-in

TOE-IN SPECIFICATIONS

Item	Specified Condition
Toe-in (total)	A + B: 0°18' +- 12' (0.3° +- 0.2°) C + D: 3.0 +- 2.0 mm (0.12 +- 0.08 in.)

If the toe-in is not within the specified range, inspect the suspension parts and replace them if necessary.

INSPECT CAMBER

Install the camber-caster-kingpin gauge or position the vehicle on the wheel alignment tester.

Inspect the camber.

Standard camber

CAMBER SPECIFICATIONS

Item	Specified Condition
Camber Right-left error	-0°56' +- 30' (-0.9° +- 0.5°) 30' (0.5°) or less

If the measured value is not within the specified range, inspect the suspension parts for damage and/or wear and replace them if necessary because camber is not adjustable.

Measure the distance from the LH rear suspension arm bracket set bolt to the RH rear axle carrier rear side set bolt as shown in the illustration.
Measure the distance from the RH rear suspension arm bracket set bolt to the LH rear axle carrier rear side set bolt as shown in the illustration.
Standard length difference: 6.0 mm (0.236 in.) or less

If the difference exceeds the specified value, adjust it by turning the camber adjusting cam and tie rod adjusting tube.
Loosen the camber adjusting cam set nut.
Loosen the tie rod adjusting tube set nuts.

Adjust the camber and toe-in by turning the adjust cam and adjusting tube.

HINT:

Adjust the camber and toe-in to the center of the specified ranges as much as possible.

Standard toe-in

TOE-IN SPECIFICATIONS

Item	Specified Condition
Toe-in (total)	A + B: 0°18' +- 6' (0.3° +- 0.1°) C + D: 3.0 +- 1.0 mm (0.12 +- 0.04 in.)

Standard camber

CAMBER SPECIFICATIONS

Item	Specified Condition
Camber Right-left error	-0°56' +- 20' (-0.9° +- 0.3°) 30' (0.5°) or less

Tighten the camber adjusting cam set nut.
Torque: 74 N*m (755 kgf*cm, 55 ft.*lbf)
Tighten the tie rod adjusting tube set nut.
Torque: 56 N*m (571 kgf*cm, 41 ft.*lbf)

How to read an adjustment chart (Using examples).
1. Measure the present alignment.
  Example:
  
  Camber (RH): -1°26' (-1.4°)
  
  Camber (LH): -2°26' (-2.4°)
  
  Toe-in (total): IN 7.0 mm (0.276 in.)
2. Mark the difference between the standard value (A) and the measured value (B) on the adjustment chart.

  Standard value:
  
  Camber: -0°56' (-0.9°)
  
  Toe-in (total): IN 3.0 mm (0.12 in.)
  
  Formula: A - B = C
  
  Camber (RH): -0°56' - (-1°26') = 0°30'
  
  Camber (LH): -0°56' - (-2°26') = 1°30'
  
  Toe-in (total): IN 3.0 - IN 7.0 = OUT 4.0
  
  Toe-in (each side): OUT 2.0
3. As shown in the example chart, read the distance from the marked point to the center of the chart, and adjust the upper and/or lower arm adjusting cams accordingly.
  Amount to turn camber adjusting cam assembly (by graduation):
  
  Scale (RH): - (Inward) 1.5
  
  Scale (LH): - (Inward) 5.5
  
  Amount to turn tie rod adjusting tube (by graduation):
  
  Angle (RH): - (Shorter) 96°
  
  Angle (LH): - (Shorter) 108°
