INSPECTION
Check the following items before performing the wheel alignment measurement.
- Tire inflation pressure
- Uneven wear of RH and LH tires, or difference of sizes
- Tire runout
- Excessive play and wear of ball joint
- Excessive play and wear of tie-rod end
- Excessive play of wheel bearing
- Right and left wheel base imbalance
- Deformation and excessive play of steering link
- Deformation and excessive play of suspension parts
Check, adjust and measure the wheel alignment in accordance with the following procedures.
| 1 | Wheel arch height (front and rear wheels) | Inspection: Refer to REAR WHEEL TOE-IN . |
|---|---|---|
| ↓ | ||
| 2 | Camber (front and rear wheels) | Inspection: Refer to CAMBER . Adjustment: Refer to FRONT CAMBER . |

| 3 | Caster (front wheel) | Inspection: Refer to CASTER . |
| ↓ | ||
| 4 | Steering angle | Inspection: Refer to FRONT WHEEL TOE-IN . Adjustment: Refer to STEERING ANGLE . |
| ↓ | ||
| 5 | Front wheel toe-in | Inspection: Refer to STEERING ANGLE . Adjustment: Refer to FRONT WHEEL TOE-IN . |
| ↓ | ||
| 6 | Rear wheel toe-in | Inspection: Refer to WHEEL ARCH HEIGHT . Adjustment: Refer to REAR WHEEL TOE-IN . |

| 7 | Thrust angle | Inspection: Refer to THRUST ANGLE . Adjustment: Refer to THRUST ANGLE . |
Scheme 11
- Park the vehicle on a level surface.
- Empty the vehicle so that it is at "curb weight". (Empty the luggage compartment, load the spare tire, jack and service tools, and fill up the fuel tank.)
- Set the steering wheel in a straight-ahead position, and stabilize the suspension by moving the vehicle in a straight line for 5 m (16 ft) or more.
- Suspend a thread from the wheel arch (point "A" in the figure below) and affix at a position directly above the center of wheel.
- Measure the distance between the point "A" and the center of wheel.
| Wheel arch height specification mm (in) (Tolerance: +12 mm -24 mm ( +0.47 in -0.94 in )) | |||
|---|---|---|---|
| Tire size | P205/60R16 P215/50R17 | P225/50R17 P225/45R18 | P225/60R17 P215/70R16 |
| Front | 403 (15.9) | 395 (15.6) | 469 (18.5) |
| Rear | 392 (15.4) | 387 (15.2) | 474 (18.7) |
Scheme 12
- Place the front wheel on the turning radius gauge. NOTE: Make sure the ground contact surfaces of the front and rear wheels are at the same height.
- Set the adapter into the center of wheel, and then set the wheel alignment gauge.
- Measure the camber angle in accordance with the operation manual for wheel alignment gauge. Model Camber (Difference between RH and LH 45' or less) P205/60R16 P215/50R17 -0°30'±0°45' P225/50R17 P225/45R18 -0°15'±0°45' P225/60R17 P215/70R16 0°00'±0°45'
Scheme 13
- Place the front wheel on the turning radius gauge. Make sure the ground contact surfaces of the front and rear wheels are at the same height.
- Set the adapter into the center of wheel, and then set the wheel alignment gauge.
- Measure the caster angle in accordance with the operation manual for wheel alignment gauge. Model Caster P205/60R16 P215/50R17 5°55' P225/50R17 P225/45R18 6°00' P225/60R17 P215/70R16 5°05'
Check the removed part for wear, damage and cracks, and then repair or replace it if defective.
Scheme 14
- Check for oil leaks.
- Move the piston rod up and down to check that it operates smoothly without any hitch.
- Check the piston rod for play as follows: Fix the outer shell in place and fully extend the rod. Set the dial gauge on the end of the rod L [10 mm (0.39 in)]. While applying a force of W [20 N (2 kgf, 4 lbf)] to the threaded part, read the dial gauge indication P 1 . Apply a force of 20 N (2 kgf, 4 lbf) from the opposite direction of "W", and then read the dial gauge indication P 2 . Play limit (P 1 + P 2 ): 0.8 mm (0.031 in)
- Replace the strut if faulty is found in the inspection or limit value is exceeded.
