#### Lead/Pull Correction Table

Step | Action | Value(s) | Yes | No
--- | --- | --- | --- | ---
DEFINITION: Lead/pull is the deviation of the vehicle from a straight path on a level road with no pressure on the steering wheel. Lead is usually caused by the following conditions:

• | Poor tire construction

• | Uneven brake assemblies

• | Improper tire and wheel alignment In the front tires (rear tires will not cause lead)

Tire construction can be a cause of lead in a vehicle. An example of this is placement of the belt. Off center belts on radial tires can cause the tire to develop a side force while rolling straight down the road, and the tire will tend to roll like a cone.

Verify that improper tire and wheel alignment is not mistaken for tire lead.

1 | Inspect and repair/replace tire/wheel assemblies for:

• | Correct tire pressure.

• | Excessive/uneven tire wear.

• | Correct tire size.

• | Excessive radial/lateral wheel runout.

• | Out of balance.
