Revised Wheel Balancing Procedure for
Consistent Balancing Results

GM Dealer Equipment

Concern
Customers may comment on a vibration or tire balance
concern while driving, usually at higher speeds. Initial
attempts at balancing the tire and wheel assemblies
may not have resolved the condition.
Note: All current Service Information, appropriate
Service Bulletins and PIs still apply to this condition.
Specific details related to the Silverado and Sierra HD
trucks are included in this bulletin to assist with tire
vibration concerns.
The 2011-2017 tire and wheel assemblies for the heavy
duty (HD) trucks, especially the dual rear wheel
(dually), have more mass and a larger overall diameter
requiring specialized equipment and care.

GM Dealer equipment MD Collet Kit 20–3116–1 is the
best device for HD wheel balancing and Radial Force
Variation (RFV) measurement using the Hunter
GSP9700.

Dual Rear Wheels (DRW)
The following information is specific to the Dual Rear
Wheel (DRW) Trucks
• Various adapters are listed below for use with the
DRW trucks. The first tool listed is the preferred
tool and will provide the best/most consistent
results.
• Preferred adapter/process

• There is a new adapter released for use with the
DRW trucks (and also works well with the single
rear wheel trucks). This kit is available through
GM Dealer Equipment (in Canada, at DESCanada) and works with the Hunter 9700
balancer.
• The kit fits Aluminum DRW wheels and allows
the normal functionality of the road force
variation balance procedure. For steel wheels it
will work better than any other adapter, but the
repeatability test referenced below may still be
required and may have a tight fit.

Bulletin No.: 10-03-10-001G
• The remaining available cones/adapters may not
produce repeatable balancing results with some
balancers. With the older tools available, it will
most likely not be possible to pass a centering
check when attempting to balance assemblies. If
the updated tools released are not used, it may
be necessary to balance the tire/wheel assembly
bypassing the centering check on the Hunter
9700 (and similar) equipment or by using a trucktype balancer that is capable of handling larger
assemblies similar to medium duty truck wheels
(Comparable to the TopKick or Kodiak trucks).

• The information provided below is not absolute, it
is only provided as guidelines to assist with
balancing the tire/wheel assemblies. This
specific procedure does not need to be used, but
any procedure used must provide repeatable
results.
• For DRW trucks ONLY, the new adapters are
available that will allow the tire/aluminum wheel
assembly to reliably pass the centering check on
the Hunter 9700 balancer (item #709-280 400 113
Haweka Pro Max GM II Kit for 8x180 and 8x210
vehicles) If this adapter is not available, use the
most appropriate adaptors, such as item #
20-1207-1 Extra Large Truck Cone Kit that
contains: Wheel Spacer # 46-309-2; Extra Large
Truck Cone # 192-92-2. (See photos below)

1. From the balance screen, press the “Perform
CenterCheck” softkey.
2. Mount the wheel on the spindle and secure with
the wing nut/ AutoClamp®.
3. If the rim runout method is selected, press “Use
Balance Mode.”

• When using truck wheel balancers, it is important
to use the proper settings on the machine for the
appropriate assembly to get within +/- 0.5 oz (15 g)
maximum balance tolerance. Typical modes are
truck, RV, or car. Refer to your balancer’s
instruction manual for proper settings.
Note: The following is a procedure that can be used on
the Hunter 9700 equipment. Other equipment can be
used, but repeatable results must be obtained.
Perform a Balance Mode CenteringCheck®
• If the wheel successfully passes the CenteringCheck®, balancing procedures can be performed.
If the wheel does not pass the CenteringCheck®,
“test spins” may be performed to check for wheel
centering repeatability.

4. Lower the hood and spin the wheel.
5. When spin is complete, raise the hood to
position the wheel with the valve stem at 12:00
o’clock and then press “Enter Valve Stem”
softkey.

2901795

2901783

6. Loosen the wing nut / AutoClamp®. Remove
the wheel from the collet and rotate wheel
position on the spindle to change valve stem
location. Re-install the wheel on the collet and
re-clamp.

8. When spin is complete, raise the hood and
position the wheel with valve stem at 12:00
o’clock and then press “Enter Valve Stem”
softkey.

9. CenteringCheck® results will appear.
• If CenteringCheck® is successful, balancing procedures can be performed. If the wheel does not
pass the CenteringCheck®, perform test spins as
described below.
• If using the new item #709-280 400 113 Haweka
Pro Max GM II Kit for 8x180 and 8x210 vehicles, it
is still possible to get a failed centering check. Remount the assembly and try again. Steel wheels
may still not pass and may require the procedure
detailed below in the “Perform a Balance Mode
CenteringCheck.”
Performing Centering Repeatability Test Spins
• Once failing a CenteringCheck® after the wheel
assembly has been mounted, and the correct
Balancer Setup is in place, test spins can be
performed. The procedure for checking centering
accuracy is as follows:

2901808

Notice: It may be necessary to disable the load roller if
balance results are considerably inconsistent, in order
to obtain better balance results of the wheel. However,
this will leave Radial Force Variation (RFV) ratings as
unknown and may be the root cause of a vibration
concern.

1. Perform a spin. Record the needed correction
weight and mark the correction weight location on
the tire with a tire pencil. This will be recorded as
“Spin 1.”

3. Perform a spin. Record the needed correction
weight and mark the correction weight location on
the tire with a tire pencil. This will be recorded as
“Spin 2.”

2. Unclamp the wheel assembly and change its
position by 90 degrees, either clockwise or
counterclockwise. Throughout the procedure,
continue the positioning using the clock motion first
used (I.e. all clockwise or all counterclockwise).

Evaluate Results:
When the two test spins have been completed, the
centering repeatability results may be evaluated.
Acceptable Results:
• If correction weight amounts and correction weight
locations remain relatively consistent, the results
can be considered valid.
• The following sample shows an acceptable result,
but only 2 samples are needed.

− The locations of the high point of RFV and
balance weight locations should be within
+- 135.°
− The balance weight should be +- 0.9 oz.

Single Rear Wheel Trucks
• Hunter Equipment has developed a bulletin specifically to assist with balancing single rear wheel
assemblies. That information is duplicated below
with the permission of the Hunter Corporation.
• For balancing the tire/wheel assembly, make sure
to use one of the following three methods to mount
the assembly. Using one of these methods should
allow the tire/wheel assembly to repeatedly pass
the centering check and allow for good RFV and
balancing measurements:
Method 1a: Preferred Method 1
2901834

• If correction weight amount varies more than
0.9 oz., or if phase varies by more than 135° then
current balancer operating condition and/or setup
is unacceptable and should be evaluated.
• Conditions that can cause unacceptable results
include:
− Incorrect Balancer Settings
− Worn Spindle Shaft
− Worn Collets / Cones
Radial Force Variation (RFV)
• When attempting to obtain the best possible RFV
measurements for a tire/wheel assembly that does
not pass the CenteringCheck®, it is necessary to
re-analyze RFV measurements to verify repeatable
results.
1. Obtain initial RFV measurement and record the
result.

2. Press the “Show Runout & Force Matching”
softkey.
3. Then press the “Runout/Matching” softkey and
follow procedure listed on the screen.
4. Mark the high point of tire and low point of
wheel assembly as indicated by the balancer.
Match Mount the assembly by removing tire
and remounting it so the two markings meet,
while exercising the bead to verify it is set
properly.
5. Remove the tire/wheel assembly and remount it
on the balance tool in a different position.
6. Re-analyze the corrected tire/wheel assembly
to verify repeatable results.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job
properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
