Common failure modes / deterioration
Rubber degradation (cracking, hardening, tearing)
Over time, the rubber can become brittle, crack, or split from repeated stress cycles, heat, chemical exposure (oil, road salt, etc.). This reduces its damping ability.
Delamination / bond failure
The bonding between the rubber and the metal interfaces can fail, leading to slippage or separation under load.
Excessive deformation / sagging
As the rubber softens or wears, the mount may deform under load, causing misalignment or increased movement under torque.
Fatigue / wear from repeated cycles
Especially under harsh driving conditions (off-road, heavy loads, aggressive acceleration/shifting), the stress cycles on the mount accelerate wear. Some aftermarket writeups claim that the factory rubber design is prone to “premature Drive Shaft Support failure” because of constant stress on the rubber.
Heat / ozone / environmental damage
Exposure to high temperatures, undercarriage heat, moisture, road debris, and ozone accelerates rubber aging.
Load shift or impact damage
If the vehicle strikes a pothole or the differential experiences shock loads, the mount may crack or tear.
