Nissan Xterra. Manual - part 437

5. Check the shock absorbers for leaks or damage.
6. Check each mounting point of the suspension components for any excessive looseness or damage.
7. Check each link, arm, and the suspension member for any damage.
8. Check the vehicle height. Refer to

FSU-26, "Wheelarch Height (Unladen*1)"

GENERAL INFORMATION AND RECOMMENDATIONS

1. A Four-Wheel Thrust Alignment should be performed.

• This type of alignment is recommended for any NISSAN vehicle.

• The four-wheel “thrust” process helps ensure that the vehicle is properly aligned and the steering wheel

is centered.

• The alignment machine itself should be capable of accepting any NISSAN vehicle.

• The alignment machine should be checked to ensure that it is level.

2. Make sure the alignment machine is properly calibrated.

• Your alignment machine should be regularly calibrated in order to give correct information.

• Check with the manufacturer of your specific alignment machine for their recommended Service/Cali-

bration Schedule.

THE ALIGNMENT PROCESS

IMPORTANT: Use only the alignment specifications listed in this Service Manual. Refer to

FSU-25, "Wheel

Alignment (Unladen*1)*6"

1. When displaying the alignment settings, many alignment machines use “indicators”: (Green/red, plus or

minus, Go/No Go). Do not use these indicators.

• The alignment specifications programmed into your alignment machine that operate these indicators

may not be correct.

• This may result in an ERROR.

2. 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.

• If using the “Rolling Compensation” method, after installing the alignment targets or head units, push or

pull on the rear wheel to move the vehicle. Do not push or pull on the vehicle body.

• If using the “Jacking Compensation” method, after installing the alignment targets or head units, raise

the vehicle and rotate the wheels 1/2 turn both ways.

NOTE:

Do not use the "Rolling Compensation" method if you are using sensor-type alignment equipment.

• Follow all instructions for the alignment machine you are using for more information.

CAMBER AND CASTER

1. Measure camber and caster of both the right and left wheels with a suitable alignment gauge and adjust

as necessary to specification.

NOTE:

Some vehicles may be equipped with straight (non-adjustable) lower link bolts and washers. In order to

adjust camber and caster on these vehicles, first replace the lower link bolts and washers with adjustable

(cam) bolts and washers.

2. If outside of the specified value, adjust camber and caster using

the adjusting bolts in the front lower link.

CAUTION:

After adjusting the camber then check the toe-in.

NOTE:

Camber changes about 3' (0.05

°) with each graduation of one

adjusting bolt. Refer to table below for examples of lower link

adjusting bolt effect on camber and caster.
