Lead Pull is the deviation from a straight path on a level road with no pressure on the steering wheel. The following are common causes of Lead Pull:

The way in which a tire is built can produce lead. An example is the placement of the belt. An off center belt on radial tires causes the tire to develop a side force while rolling straight down the road. The tire tends to roll like a cone. Use the Radial Tire Lead/Pull Correction chart to make sure that the wheel alignment is not mistaken for tire lead. Rear tires usually do not cause lead/pull.

The front brakes are dragging.

Refer to Brake Rotor Tolerance and Brake Pad Inspection and Brake Caliper Inspection in Disc Brakes.

The front wheel alignment is out of specification.

1. Check the wheel alignment.
2. Perform wheel alignment.

Refer to Wheel Alignment Measurement in Wheel Alignment.

The tires will not balance.

1. Inspect the tire(s).
2. Service and/or replace as needed.

Refer to Abnormal or Excessive Tire Wear in Suspension General Diagnosis or Tires Description .

The front or rear transverse leaf springs are broken or sagging.

1. Inspect the springs.
2. Service as needed.

Refer to Front Transverse Spring Replacement in Front Suspension Rear Transverse Spring Replacement in Rear Suspension.

The tire pressure is incorrect.

Inflate tire(s) to proper specifications.

Refer to Tire Inflation Pressure Specifications in Maintenance and Lubrication.

The tires are mismatched or the tire wear is uneven.

Service and/or replace as needed.

Refer to Abnormal or Excessive Tire Wear in Suspension General Diagnosis.
