SERVICE INFORMATION
To increase tire/wheel assembly balancing accuracy, proper steps should be followed:


Make sure to use the correct size wheel centering collet (do not use a cone).



Make sure to use a flange plate and stud set to secure the tire/wheel assembly on the balancer (do not
use a cup).
NOTE: For Hunter balancing equipment – specific centering and mounting tools (collets and flange
plates) for Applied Vehicles are available – see page 5.



Perform proper wheel mounting and centering checks.

Refer to the information in this bulletin for details on the above points.

Infiniti Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are properly trained
individuals who have the equipment, tools, safety instruction, and know-how to do a job properly and safely. NOTE: If you believe
that a described condition may apply to a particular vehicle, DO NOT assume that it does. See your Infiniti retailer to determine if this
applies to your vehicle.

Wheel Centering Quick Check
1. Run the tire/wheel assembly on the wheel balancer in the “non-round-off” mode and record the imbalance
measurements.


Mark the location where the weight(s) are requested.

2. Loosen the wing nut while keeping the tire/wheel assembly from turning on the balancer shaft.
3. Rotate the tire/wheel assembly 180 degrees on the balancer shaft, and then secure it with the wing nut.
4. Run the tire/wheel assembly again.


The imbalance values should be within ¼ ounce (7 grams) of the values in Step 1.



The weight(s) should be located within 2-3 inches (50-75 mm) of the locations in Step 1.
