Motor Mount

Auto Systems and Repair

Motor mounts are used to secure the drivetrain to the vehicle body/frame and protect it from engine vibrations. They consist of a rubber insulator between two strong metal brackets.

Symptoms of Wear or Failure

  • Excessive engine vibration transmitted to the body/frame
  • Clunking and/or excessive engine movement on acceleration

Related Repair Advice

  • As with all rubber components, dry rot and age deteriorates the integrity of the motor mount over time
  • A broken motor mount allows the engine and transmission too much movement and can cause potential damage to components that depend on a stable engine (e.g. axles)
  • Excess engine movement caused by a failed mount can damage other mounts. When a failed motor mount is replaced, the other mounts should be inspected for damage
