Why Replace It, Engine mounts are crucial for:
- Locating and supporting the engine
- Absorbing vibration and engine torque under acceleration, braking, and cornering
- When this mount deteriorates or fails, you can expect, Increased vibration transmitted to the cabin, steering, or pedals
- Clunks, bangs, or loud noises during acceleration, deceleration, or gear changes from engine movement against the chassis
- Visual signs such as leaking black fluid from the mount, sagging of tailpipes (due to dropped mounting), or visible damage to rubber or metal components
Common Failure Causes
- Age-related rubber degradation: over time, rubber hardens, cracks or de-bonds, causing loss of damping and allowing engine movement
- Fluid leakage (hydraulic version): loss of damping fluid due to seal failure accelerates failure
- Fluid contamination: oil, coolant, or other contaminants degrade the rubber material
- Vehicle abuse or stress: aggressive driving, hard launches, or previous accidents can warp or break mounts
- Worn or cracked brackets: even if the rubber is intact, the aluminium bracket can be damaged or corroded, reducing effectiveness
