Symptoms of a Worn or Failing Engine Mount - If your engine mount is worn, you may notice:

  • Excessive vibration or shaking at idle or during acceleration.
  • Clunking or knocking noises when shifting gears or accelerating.
  • Engine movement or rocking under load.
  • Visible cracks or leaks in the rubber or hydraulic fluid.
  • A sagging or misaligned engine in the bay.

These symptoms suggest it’s time for replacement before further damage occurs.

Common Causes of Failure - Engine mounts naturally wear out due to:

  • Age and fatigue (rubber hardens, cracks, or loses elasticity).
  • Oil or coolant leaks that deteriorate the rubber.
  • Harsh driving or torque loads from aggressive acceleration.
  • Incorrect installation or over-tightened fasteners.
  • Corrosion on the mounting brackets or bolts.


Why Replace an Engine Mount? - Replacing your mount restores stability, comfort, and safety.

  • Prevents engine movement that can damage hoses or wiring.
  • Reduces vibration and noise inside the cabin.
  • Maintains alignment of the drivetrain and transmission.
  • Avoids premature wear on suspension and steering components.
  • Restores factory ride comfort and performance feel.
