• 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.
