Nissan Sentra Service Manual: Wheel alignment

Inspection

DESCRIPTION

Measure the wheel alignment under unladen conditions.

NOTE:

“Unladen conditions” means that fuel, engine coolant, and lubricants are full. Spare tire, jack, hand tools and mats are in designated positions.

PRELIMINARY

Check the following:

  1. Tires for improper air pressure and wear.
  2. Road wheels for runout. Refer to WT-46, "Inspection".
  3. Wheel bearing axial end play. Refer to RAX-5, "Inspection".
  4. Shock absorber operation.
  5. Each mounting part of suspension for looseness and deformation.
  6. Rear suspension beam for cracks, deformation, and other damage.
  7. Vehicle height (posture).

GENERAL INFORMATION AND RECOMMENDATIONS

  1. A Four-Wheel Thrust Alignment should be performed.
  1. Make sure the alignment machine is properly calibrated.

THE ALIGNMENT PROCESS

IMPORTANT:

Use only the alignment specifications listed in this Service Manual. Refer to RSU-15, "Wheel Alignment (Unladen*1)".

  1. When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or minus, Go/No Go). Do NOT use these indicators.
  1. Most camera-type alignment machines are equipped with both "Rolling Compensation" method and optional "Jacking Compensation" method to "compensate" the alignment targets or head units.

    "Rolling Compensation" is the preferred method.

NOTE:

Do not use the "rolling compensation" if you are using sensor-type alignment equipment.

CAMBER INSPECTION

Camber : Refer to RSU-15, "Wheel Alignment (Unladen*1)".

TOTAL TOE-IN INSPECTION

Measure the total toe-in using following procedure. If it is out of the specification, inspect and replace any damaged or worn rear suspension parts.

WARNING:

  1. Bounce the rear of the vehicle up and down to stabilize the vehicle height (posture).
  2. Push the rear wheel to move the vehicle straight ahead about 5 m (16 ft).
  3. Put a mark on the base line of the tread (rear side) of both tires at the same height of hub center. These are measuring points.


  1. Measure the distance (A) from the rear side.
  2. Push the rear wheel to move the vehicle slowly ahead and to rotate the wheels 180 degrees (1/2 turn).

CAUTION:

If the wheels have rotated more than 180 degrees (1/2 turn), try the above procedure again from the beginning. Do not push the vehicle backward.

  1. Measure the distance (B) from the front side.

Total toe-in : Refer to RSU-15, "Wheel Alignment (Unladen*1)".
