Preliminary Check
Steering and vibration complaints are not always the result of improper alignment. An additional item to be checked is the possibility of tire lead due to worn or improperly manufactured tires. "Lead" is the deviation of the vehicle from a straight path on a level road without hand pressure on the steering wheel. "Suspension, Wheels and Tires Symptom Diagnosis: *contains a procedure for determining the presence of a tire lead problem. Before making any adjustment affecting toe setting, the following checks and inspections should be made to ensure correctness of alignment readings and alignment adjustments:
1) Check all tires for proper inflation pressures and approximately the same tread wear.
2) Check for loose of ball joints. Check tie rod ends; if excessive looseness is noted, it must be corrected before adjusting.
3) Check for run-out of wheels and tires.
4) Check vehicle trim heights; if out of limits and a correction is to be made, it must be made before adjusting toe.
5) Check for loose of suspension arms.
6) Check for loose or missing stabilizer bar attachments.
7) Consideration must be given to excess loads, such as tool boxes. If this excess load is normally carried in vehicle, it should remain in vehicle during alignment checks.
8) Consider condition of equipment being used to check alignment and follow manufacturer's instructions.
9) Regardless of equipment used to check alignment, vehicle must be on a level surface both fore and aft and transversely.

Toe Inspection and Adjustment

Toe is adjusted by changing the tie rod length. Loosen right and left tie rod end lock nuts first and then rotate right and left tie rods (1) by the same amount to align toe-in to specification. In this adjustment, right and left tie rods should become equal in length ("A" in the figure). Before rotating tie rods, apply grease between tie rods and rack boots so that boots won't be twisted. After adjustment, tighten lock nuts to specified torque and make sure that rack boots are not twisted.
Tightening torque
Tie rod end lock nut (a): 45 Nm (4.5 kgf-m, 33.0 ft. lbs.)

Camber and Caster Inspection
Should camber or caster be found out of specifications upon inspection. If it is in damaged, loose, bent, dented or worn suspension parts, they should be replaced. If it is in vehicle body, repair it so as to attain specifications.
To prevent possible incorrect reading of camber or caster, vehicle front end must be moved up and down a few times before inspection.

Steering Angle Inspection

When tie rod or tie rod end was replaced, check toe and then also steering angle with turning radius gauge (1). If steering angle is not correct, check if right and left tie rods are equal in length ("A").

NOTE: If tie rod lengths were changed to adjust steering angle, reinspect toe-inch.

Steering angle
inside: 39° ± 3°
outside: 34° ± 3°

Side slip (reference information)
For inspecting front wheel side slip with side slip tester:
If side slip exceeds limit, toe-in or front wheel alignment may not be correct.
Side slip limit
Less than 3 mm/m (Less than 0.118 inch/3.3 ft.)
