More About Drivetrain Mounts

For safety and smoothness, periodically inspect and replace all drivetrain mounts that show signs of looseness, cracking, or breakage. Worn, hardened, or broken engine mounts, transmission mounts, and differential mounts allow drivetrain components to move out of place, resulting in annoying noise, vibration, and harshness. Broken drivetrain mounts are also a safety hazard that can cause a loss of vehicle control and additional vehicle damage.
