⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the vehicle to cool down before inspecting the exhaust system if necessary.

Symptoms

•Shaking or vibrating felt in the steering wheel or the entire vehicle during acceleration
•Increased vibration at higher speeds (typically above 50 mph)
•Potential noise accompanying the vibration, such as a rumbling or grinding sound
•Noticeable loss of power during acceleration
•Possible uneven tire wear observed visually or through inspection

Diagnostic Steps

1
Inspect tires for uneven wear and ensure they are properly inflated.
2
