Replace the part when it has lost its ability to control engine movement and damp vibration. Typical triggers to replace the centre mount include:
- Hard clunk or bang on acceleration, deceleration or gear changes (engine shifting against chassis).
- Excessive vibration into the cabin, especially at idle or specific RPM bands.
- Visible damage — torn, separated rubber, oil-soaked or collapsed mount/bushing, or corrosion of mating faces.
Common issues & failure causes
- Rubber deterioration: age, heat cycling and mechanical fatigue cause the rubber to harden, crack or de-bond from the metal, reducing isolation and allowing increased engine movement.
- Fluid contamination: oil or coolant leaks accelerate rubber breakdown (softening or swelling), commonly seen on older engines where leaks occur.
- Mechanical shock / abuse: repeated hard launches, aggressive shifting or collisions can cause sudden mount failure or promote early fatigue.
- Bracket wear / corrosion: the bushing may be fine, but the aluminium bracket can crack, corrode, or the bushing may need pressing into a worn bracket — which is why some techs prefer replacing the full assembly.

Product Overview
This precision-engineered engine mount securely holds your
engine in place while absorbing vibrations and road shocks. Manufactured from high-grade
steel and vibration-resistant rubber or hydraulic components, it ensures
long service life even under demanding driving conditions.
Key Features & Benefits
- OEM-equivalent
performance – Direct replacement for part number 9A137502322.
- Enhanced
vibration isolation – Reduces cabin noise and harshness for a
smoother, quieter drive.
- Durable
construction – Corrosion-resistant housing with high-quality bonding
for long life.
- Precision
fit – Matches factory specifications for fast, trouble-free
installation.
- Improves
ride quality and handling – Maintains correct engine position and
drivetrain geometry.

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.
