Pre-Alignment Checks

For proper inspection and adjustment of the wheel alignment, do these checks

Scheme 4

2. Make sure the suspension is not modified.
3. Make sure the fuel tank is full, and that the spare tire, the jack, and the tools are in place on the vehicle.
4. Check the tire size and tire pressure. Tire size: Front/Rear: P235/45R18 94V Tire pressure (at cold): Front/Rear: 230 kPa (2.3 kgf/cm 2 , 33 psi)
5. Check the runout of the wheels and tires (see «WHEEL BEARING END PLAY INSPECTION»(/acura/tsx/ii-2008-2014/remont/wheel-alignment/#front-and-rear-suspension-v6) ).
6. Check the suspension ball joints (Raise and support the vehicle (see «LIFT AND SUPPORT POINTS»(/acura/tsx/ii-2008-2014/remont/oem-general-information/#general-information-v6__lift-and-support-points) ). Hold a tire with your hands, and move it up and down and right and left to check for movement).
7. Before doing alignment inspections, be sure to remove all extra weight from the vehicle, and no one should be inside the vehicle (driver or passengers).
8. Lower the vehicle to the ground. Bounce the vehicle up and down several times to stabilize the suspension.
9. Check that the steering column is set at the center tilt position and the center telescopic position.

Caster Inspection

Use commercially available computerized four wheel alignment equipment to measure wheel alignment (caster, camber, toe, and turning angle). Follow the equipment manufacturer's instructions.

1. Check the caster angle. Caster angle: 3°52' +10 -50 ' (Maximum difference between the right and left side: 0 ° 30') If the measurement is within specifications, measure the camber angle. If the measurement is not within specifications, check for bent or damaged suspension components.

Camber Inspection

Use commercially available computerized four wheel alignment equipment to measure wheel alignment (caster, camber, toe, and turning angle). Follow the equipment manufacturer's instructions.

1. Check the camber angle. Camber angle: Front: -0 ° 03' ±30' Rear: -1° 12' ±30' (Maximum difference between the right and left side: 0 ° 30') If the measurement is within specifications, measure the toe-in. If the measurement is not within specifications, check for bent or damaged suspension components.

Rear Toe Inspection/Adjustment

Use commercially available computerized four wheel alignment equipment to measure wheel alignment (caster, camber, toe, and turning angle). Follow the equipment manufacturer's instructions.

Scheme 5

2. Check the toe with the wheels pointed straight ahead. Front toe-in: 0±2 mm (0±0.08 in) If adjustment is required, go to step 3. If no adjustment is required, remove the alignment equipment.
3. Loosen the tie-rod end locknuts (A) while holding the flat surface sections (B) of the tie-rod end with a wrench, and turn both tie-rods (C) until the front toe is within specifications.
4. After adjusting, tighten the tie-rod end locknuts to the specified torque. Reposition the rack-end boot if it is twisted or displaced.

Turning Angle Inspection

Use commercially available computerized four wheel alignment equipment to measure wheel alignment (caster, camber, toe, and turning angle). Follow the equipment manufacturer's instructions.

Scheme 7

1. Turn the wheel right and left while applying the brake, and measure the turning angle of both wheels. Turning angle: Inward: 36 °59' ±2° Outward (reference): 30 ° 23'
2. If the measurement is not within the specifications, even up both sides of the tie-rod threaded section length while adjusting the front toe. If it is correct, but the turning angle is not within the specifications, check for bent or damaged suspension components.
