Rear Suspension

Preparation for Inspection and Adjustment

Steering and vibration complaints are not always the result of improper wheel alignment. An additional item to be checked is the possibility of tire lead due to worn or improperly manufactured tires. "Lead" is the vehicle deviation from a straight path on a level road without hand pressure on the steering wheel. Refer to Tire Inspection Tire Inspection
in order to determine if the vehicle has a tire lead problem. Before inspecting rear wheel alignment and making any adjustment affecting wheel alignment, perform the following checks, inspections and repair / replacement to ensure correct measurements and adjustments.

- Check all tires for proper inflation pressure. Adjust pressure for any improperly inflated tire(s).
- Check that all tires are of the same type and brand and also they have approximately the same tread wear. Replace all tires with new ones if necessary.
- Check rear wheel bearings for damage. Replace damaged bearing(s) with new one(s).
- Check wheels and tires for deformation. Repair or replace them if necessary. Testing and Inspection
- Check that rear suspension system is properly installed and free of damage. Component Tests and General Diagnostics
- Check suspension components for bends, dents, wear or other damage.
- Place vehicle on level surface in unloaded state.
- Push vehicle body to bounce vehicle up and down several times to stabilize rear suspension.
- Check that ground clearance on one side is approximately the same as that on the other side.

Toe and Camber Inspection

- Push vehicle body to bounce vehicle up and down several times to stabilize rear suspension.
- Move vehicle forward and backward several times to stabilize suspension if vehicle has been hoisted.
- Check that toe and camber are in specified ranges using wheel alignment tester. If check result is not as specified, adjust toe and camber.

Rear toe
: IN 2.0 +/- 1.0 mm (0.08 +/- 0.04 in.)

Rear camber
: -1� 15' +/- 0� 30'

Toe and Camber Adjustment

NOTE:

- Toe and camber adjustment should be performed primarily on control rods. If necessary amount of adjustment exceeds the amount of adjustment possible with control rods, then make adjustment on lower arms.
- If toe and camber are found greatly deviating from specified ranges, turn each of adjusting bolts on control rods and lower arms until its center mark points directly upward. Then perform adjustment on control rods and, if more adjustment is still necessary, on lower arms.






Control rod

1) Remove each control rod lock nut (1).
2) Temporarily tighten new control rod lock nuts.





3) Turn adjustment bolts (1) on right and left control rods by same amount to adjust toe and camber to values in specified ranges.

NOTE:
Turning bolt in direction [a] causes camber to change toward "+" and toe toward "IN"; turning it in direction [b] causes camber to change toward "-" and toe toward "OUT".









4) Tighten each control rod lock nut to specified torque with control rod adjustment bolt held after adjustment.

Tightening torque
Control rod lock nut 75 Nm (7.6 kgf-m, 55.5 lbf-ft)

Lower arm

5) Remove each lower arm lock nut (1).
6) Temporarily tighten new lower arm lock nuts.











7) Turn lower arm adjustment bolts (1) at right and left by same amount to adjust toe and camber to values in specified ranges.

NOTE:
Turning bolt in direction [a] causes camber to change toward "+" and toe toward "OUT"; turning it in direction [b] causes camber to change toward "-" and toe toward "IN".









8) Tighten lower arm lock nut to specified torque with lower arm adjustment bolts held after adjustment.

Tightening torque
Lower arm lock nut 75 Nm (7.6 kgf-m, 55.5 lbf-ft)
