NOTE:
-
Unloaded condition: Fuel tank is full. Engine coolant and engine oil are at specified level. Jack and tools are in designated position.
-
Difference between the left and right camber and caster angles must be within 1°.
Steering Angle Adjustment
1. Loosen the tie-rod end locknuts.
2. Remove the steering gear boot clamp.
3. Rotate the tie rod and adjust the steering angle.
NOTE:
-
The travel distance of the right and left tie rods should be the same.
4. Rotate the tie rod and adjust so that dimension L shown in the figure does not exceed the specification.
-
Specification
-
49.8—63.8 mm {1.97—2.51 in} (difference between left and right: 3 mm {0.1 in} or less)
5. Tighten the tie-rod end locknuts.
-
Tightening torque
-
69—98 N·m {7.1—9.9 kgf·m, 51—72 ft·lbf}
6. Verify that the boot does not have any twisting and install the boot clamp.
7. After steering angle adjustment, always inspect and adjust the total toe-in. (See Total Toe-in Adjustment.)
Camber Adjustment
CAUTION:
-
Adjust the camber before adjusting the caster.
-
When adjusting the camber, abnormal noise may occur if the adjusting cam bolt and nut are reused after removing the adjusting cam bolt installation nut. When adjusting the camber, be careful not to completely remove the adjusting cam bolt installation nut.
-
If the installation nut for the adjusting cam bolt is removed, replace the adjusting cam bolt and nut with new ones.
1. Loosen the installation nut of the adjusting cam bolt on the front side of the front lower arm.
2. Rotate the adjusting cam bolt in either direction to adjust the camber. Specification
