Important safety information - read before proceeding

•Always use jack stands when working under the vehicle.
•Disconnect the battery before working on electrical systems.
•Allow the engine to cool before performing any repairs on the engine or transmission.

Symptoms

•Shaking or shuddering felt through the steering wheel or body during acceleration
•Vibration increases with speed and may decrease when coasting
•Potential noise accompanying the vibrations, such as clunking or grinding
•Difficulty maintaining speed or a noticeable loss of power
•Uneven tire wear or misalignment may be present

Diagnostic Steps

1
Inspect tires for uneven wear and proper inflation; check for bulges or damage.
