Cause: This may be caused by a road wheel/tire assembly imbalance and/or temporary tire flat-spotting.
Action: Should a customer express this concern, refer to the Service Instruction outlined below.

PARTS:
Wheel weights

Locally sourced

Quantity: As required

TOOLS:
Hunter 9700-series wheel balancing equipment
Hunter / Haweka hub-to-wheel five-finger clamp

WARRANTY:
NOTE: Repair procedures are under constant review, and therefore times are subject to change;
those quoted here must be taken as guidance only. Always refer to TOPIx to obtain the latest repair
time.
NOTE: DDW requires the use of causal part numbers. Labor only claims must show the causal part
number with a quantity of zero.

NOTE: Normal Warranty policies and procedures apply.

SERVICE INSTRUCTION:
1.

NOTE: Step 1 is part of the initial vehicle preparation process. No claim should be initiated if
this step resolves the concern.

NOTE: Until flat-spots are removed, significant steering wheel vibration / shimmy may be
present, even if the car has only stood overnight. A test drive is required to ensure temporary tire
flat spots are removed. For longer term flat spots, a longer drive may be required. The test drive
should be carried out on normal open roads to allow the highest speed that speed limits and road /
traffic conditions allow.
If the vehicle has experienced a steering wheel vibration / shimmy during the Pre-Delivery Inspection (PDI)
road test, refer to Technical Bulletin LTB00466NAS. If after performing the Service Instruction therein the
concern is still evident, continue to step 3 below.
2. If a customer concern is being resolved, perform the following:
Visually inspect the wheel and tire assemblies for damage, missing wheel weights, etc.
Adjust the tire pressure to 29psi (2.0bar).
Drive the vehicle for a minimum of 10 miles (15km) before attempting to assess steering wheel vibration /

shimmy.
• If the level of steering wheel vibration is acceptable, no further action is required. Refer to the tire
pressure label and adjust the tire pressures to the recommended cold tire pressures.
• If the levels of steering wheel vibration is unacceptable, continue to step 3.
3. Immediately upon returning to the workshop, lift and support the vehicle to avoid inducing further tire flat
spots (see TOPIx Workshop Manual, Section 100-02).
4. Remove all four road wheel/tire assemblies.

5.

NOTE: When using adhesive weights, use

the attachment arm on the balancing equipment
to ensure accurate weight positioning.
Mount each wheel/tire assembly (using the correct
wheel-fitting attachment) to the balance machine
and balance until the residual imbalance dynamic is
minimized.
Target is 0g (zero grams) on each plane;

maximum is inner 5g / outer 5g.
Use the 'bulls-eye' balancing mode to minimize

residual imbalance.

6. The maximum tire road force variations (RFV) for each road wheel/tire assembly should be 60 Newton (6.1
kgf / 13.4 lbf) 1st harmonic RFV, 100 Newton (10.2 kgf / 22.5 lbf) peak-to-peak.
7. If these levels cannot be achieved, perform the following:

8.

Remove the tire.
Follow the match mounting procedure as detailed by the Hunter machine.
Mark the high point of 1st harmonic RFV on the outer (and inner for future reference) sidewall of the tire.
Install the lowest 1st harmonic RFV wheel/tire assemblies to the front axle.
Print out the results of balance and force variation (before and after); attach to repair order.

NOTE: If RFV equipment is not available
and the tire has not been removed from the
wheel and the RFV spot (red dot) is still
visible, install wheel/tire assembly with red
dot 'up'.
Prior to tightening the wheel nuts, the marked high
point of RFV must be installed to the vehicle with
the RFV high point 'up'.

9.

NOTE: Do not brace the wheel while tightening the nuts as this can disturb the match
mounting.
Install the road wheel/tire assemblies on to the vehicle.

10. Tighten wheel nuts to the specified torque (see TOPIx Workshop Manual, Section 204-04).
11. Lower the vehicle.
12. Drive the vehicle approximately 5 miles (7km) on normal roads and up to speeds of approximately 50 mph
(80kph) to verify correction of steering wheel vibration / shimmy.
