Hummer vehicles are built for power, adventure, and off-road capability. Whether you drive a Hummer H1, H2, or H3, our pro technicians have the knowledge and tools to keep your rugged vehicle performing at its best.


With more than one auto repair shop location, Toole's Garage provides specialized service for Hummer owners, ensuring your vehicle stays fit for any terrain. From routine maintenance to 4x4 system diagnostics, we help keep your Hummer tough.


Best Hummer Maintenance

Hummers are engineered for durability and extreme conditions, but routine maintenance is key to preventing premature wear and maximizing performance. Our team follows Hummer’s factory service guidelines, ensuring your vehicle’s engine, drivetrain, off-road components, and everything in between receive the care they need.


Top 3 Hummer Maintenance Tips

  1. Inspect and Maintain Your 4x4 System – Keeping your transfer case, differentials, and axles in top condition ensures smooth off-road performance.
  2. Check Suspension and Tires Regularly – Hummers are heavy-duty vehicles that rely on sturdy suspension and proper tire pressure for stability and ride comfort. Routine inspections prevent uneven wear and handling issues.
  3. Monitor Fluid Levels for Peak Performance – Hummer engines and drivetrains require regular oil, coolant, and transmission fluid checks to prevent overheating and maintain efficiency.
