Front End Alignment Check Procedure
Front End Alignment Check Procedure (Adjust if Needed):IMPORTANT:
^ A copy of the Alignment Machine Printout showing BEFORE and AFTER alignment readings MUST be attached to the Repair Order (for alignment).
^ A copy of the alignment machine calibration certification must be attached to the Repair Order.
^ Failure to attach this information may result in debit of the Claim.
^ This information should be kept in the vehicle's service history file.
1. Check the vehicle's front end alignment and adjust Toe-in, if needed.
^ Only Toe-in can be adjusted on the front suspension of the 350Z.
^ The Camber and Caster are not adjustable.
It is absolutely critical that the TOE is properly set on the 350Z.
For details on Front End Alignment, refer to the FSU section/Wheel Alignment Inspection and Toe-in Inspection and /Service Data/Wheel Alignment (Unladen) in the Electronic Service Manual (ESM).

IMPORTANT:
^ You must use a quality alignment machine that will give accurate results when performing alignment checks.
^ An alignment machine such as the Hunter Series 811 listed in the Nissan TECH-MATE Catalog (or equivalent) should be used.
^ Your alignment equipment should be regularly calibrated in order to give correct information.
^ HUNTER recommends that:
-> Standard conventional style Alignment Machines (internal reference sensors) should be checked (and calibrated if necessary) every six months.
-> "External reference" Alignment Machines (image based) should be checked once a year. Documentation of this "System Check" will serve as the calibration certification.
-> Obviously, if any instrument is dropped, or damaged in some way, calibration should be checked immediately.
^ The alignment rack itself should be capable of accepting the 350Z.
^ The rack should be checked to ensure that it is level.
^ Some newer Hunter or other brand alignment machines are equipped with an optional "Rolling Compensation" method.
-> Do NOT use this method to compensate the sensors (alignment targets or heads) when aligning the 350Z.
-> Use the "Jacking Compensation Method" for any Alignment Targets or Heads sensors. You'll need to raise the vehicle to perform this compensation.
ALSO:
^ To display the Alignment Settings, many alignment machines use a green/red or plus/minus or Go/No Go "indicator".
^ Don't use these indicators. They may cause some confusion that may result in a wrong toe setting.
^ The alignment specifications used to make the color change may not be correct in your machine. This may result in an ERROR.
-> You should check the specification and tolerance information in your machine to make sure it matches the specifications listed in the ESM or Chart 1 in this TSB.
^ Refer to the actual number to correctly set the TOE.
2. After you have checked and adjusted (if necessary) the Toe-in:
^ Print out both BEFORE and AFTER measurements,
^ Attach them to the Repair Order.
3. Road test the vehicle to make sure:
^ The steering wheel is "centered".
^ The road noise is minimized.
