Test Description

The numbers below refer to the step numbers in the diagnostic table:

A build-up of foreign material on a tire and wheel assembly and/or a damaged, abnormally or excessively worn tire and wheel assembly could cause a vibration disturbance.

Tire and wheel assemblies that exhibit excessive runout when measured while mounted on the vehicle, may or may not be contributing to, or causing a vibration disturbance. On-vehicle runout, if present, could contribute to, or cause a vibration disturbance, but the cause of the on-vehicle runout may not be the tire and wheel assemblies.

Tire and wheel assemblies that exhibit excessive runout when measured off of the vehicle could cause a vibration disturbance.

Tire and wheel assemblies that exhibit marginal runout--within acceptable limits, but close to the maximum--when measured off of the vehicle could still be contributing to a vibration disturbance, if its mating hub/axle flange also exhibits marginal runout. When the tire and wheel assembly and the hub axle flange are mounted to each other, the combined stack-up of their marginal amounts of runout could combine to produce an excessive amount of runout, which could cause a vibration disturbance.

Brake rotors and/or brake drums, if equipped, that exhibit excessive imbalance could contribute to, or possibly cause a vibration disturbance.

A hub/axle flange and/or wheel studs that exhibit excessive runout could cause a vibration disturbance.

When the tire and wheel assembly and the hub axle flange are mounted to each other, the combined stack-up of their marginal amounts of runout could combine to produce an excessive amount of runout, which could cause a vibration disturbance. Match-mounting or vectoring the tire and wheel assembly to the hub/axle flange will modify the amount of combined runout.

Force variation may be present in a tire and wheel assembly that exhibited acceptable balance and runout. Force variation, if present, could contribute to, or cause a vibration disturbance.

Vibration disturbances could be affected by, or possibly caused by, components that are susceptible to steering input and/or torque-load input.

On-vehicle balancing, or finish-balancing can be used to reduce small amounts of imbalance which may be present as a result of the combined stack-up of the tire and wheel assembly with other components which may exhibit marginal balance.

Yes

Has the Vibration Analysis - Road Testing table been completed?

Go to Step 2

Go to Vibration Analysis - Road Testing

Based on the Vibration Analysis - Road Testing table, is the concern first-order tire and wheel assembly related?

Go to Step 4

Go to Step 3

Based on the Vibration Analysis - Road Testing table, is the concern second-order, or higher-order tire and wheel assembly related?

Go to Step 18

Go to Vibration Analysis - Road Testing

Visually inspect the tire and wheel assemblies for the following:

•	Debris build-up, such as packed mud, undercoating, ice/snow buildup, road tar, etc.

•	Damage, abnormal or excessive wear

Refer to Tire and Wheel Inspection .

Do any of the tire and wheel assemblies exhibit any of the conditions listed?

Go to Step 5

Go to Step 6

Remove the debris from the tire and wheel assemblies.
Replace the damaged, abnormally or excessively worn wheels or tires as necessary.

Did you complete the repair or replacement?
