Front Wheel Alignment
COMPONENTS
PRELIMINARY INSPECTION
WARNING: Always adjust the alignment with the vehicle on a flat surface.
NOTE: If alignment is out of specification, inspect and replace any damaged or worn rear suspension parts before making any adjustments.
1. Check and adjust the wheel alignment with the vehicle under unladen conditions. "Unladen conditions" means that the fuel, coolant, and lubricant are full; and that the spare tire, jack, hand tools and mats are in their designated positions.
2. Check the tires for incorrect air pressure and excessive wear.
3. Check the wheels for run out and damage. Refer to "Inspection".
4. Check the wheel bearing axial end play. Refer to "WHEEL BEARING INSPECTION".
5. Check the shock absorbers for leaks or damage.
6. Check each mounting point of the suspension components for any excessive looseness or damage.
7. Check each link, arm, and the rear suspension member for any damage.
8. Check the vehicle height. Refer to "Wheelarch Height (Unladen *1).
- For air leveling vehicles, verify the level using Consult-II memory register 1103 and set to 0 +/- 10 mm (0 +/- 0.39 inch) as necessary.
CAMBER AND CASTER
1. Measure camber and caster of both the right and left wheels with a suitable alignment gauge and adjust as necessary to specification.
Camber : Refer to "Front Wheel Alignment"
2. If outside of the specified value, adjust camber and caster using the adjusting bolts in the front lower link.
CAUTION: After adjusting the camber then check the toe-in.
NOTE: Camber changes about 3' (0.11°) minutes with each graduation of one adjusting bolt. Refer to table below for examples of lower link adjusting bolt effect on camber and caster.
3. Tighten the adjusting bolt nuts to specification. Refer to "Components".
TOE-IN
WARNING:
- Always perform the following procedure on a flat surface.
- Make sure that no person is in front of the vehicle before pushing it.
1. Bounce the front of vehicle up and down to stabilize the vehicle height (posture).
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of the tread (rear side) of both front tires at the same height as hub center as shown. These marks are measuring points.
4. Measure the distance "A" on the rear side of the front tires as shown.
5. Push the vehicle slowly ahead to rotate the wheels 180° degrees (1/2 a turn).
CAUTION: If the wheels have rotated more than 180° degrees (1/2 turn), start this procedure again from the beginning. Never push the vehicle backward.
6. Measure the distance "B" on the front side of the front tires at the same marks as shown. Total toe-in is calculated as "A" -"B".
Total toe-in : Refer to "Wheel Alignment (Unladen *1).
7. Adjust the toe-in by varying the length of the steering outer tie-rods.
a. Loosen the outer tie-rod lock nuts.
b. Adjust the toe-in by screwing the outer tie-rods in or out.
Standard length "L" : Refer to "Steering Outer Socket and Inner Socket".
c. Tighten the outer tie-rod lock nuts to specification.
Lock nut : Refer to "Removal and Installation".
FRONT WHEEL TURNING ANGLE
NOTE: Check front wheel turning angle after the toe-in inspection.
1. Place front wheels on turning radius gauges in straight ahead position and rear wheels on stands so that vehicle can be level. Check the maximum inner and outer wheel turning angles for LH and RH road wheels.
2. Start engine and run at idle, turn steering wheel all the way right and left, measure the turning angle.
Wheel turning angle : Refer to "Wheel (full turn) Alignment (Unladen *1)".
- Any turning angles are not adjustable. If any of steering angles are out of the specification, check if the following parts are worn or damaged.
- Steering gear
- Steering column
- Front suspension components If found that they are worn or damaged, replace them with new ones.
