• Uneven tire wear: Premature or uneven wear on the tires, especially on one side of the vehicle.
• Loose or wobbly wheels: Excessive play or movement in the wheels when lifted off the ground.
• Increased fuel consumption: Worn bearings can create additional resistance, leading to reduced fuel efficiency.

Replacement Procedures

Replacing front wheel bearings on a 2008 Chevy Impala requires specialized tools and mechanical skills. It is recommended to consult a qualified mechanic for this task. The general steps involved include:
