Easy-to-recognize signs
The tripod is the part that connects the engine - gearbox cluster with the body or auxiliary frame, while limiting movement and reducing vibration transmitted from the engine into the cabin. Depending on the car model, the tripod can use elastic rubber, hydraulic structure or controlled type.
According to a technician at the Ninety Eight Auto Auto Repair, Maintenance and Care Center (Thu Duc City, Ho Chi Minh City), when the tripod or elastic rubber part is worn out, cracked, torn, deformed or loses its shock-resistant capability, vibration can be transmitted more into the cockpit.
An easy-to-recognize sign is that the car vibrates when the engine explodes without load. People sitting in the cabin can feel vibrations through the steering wheel, seats or the car floor. Some cases also experience unusual noises.
Vibration can be clearer when the driver lightly presses the accelerator to increase the speed. When the engine changes torque, the tripod must control the movement of the engine - gearbox. If the tripod has degraded, this movement may be larger than normal, causing the car to vibrate strongly or make noise.
Another sign is that the car vibrates or makes noise when shifting the gear lever between positions such as D and R on an automatic transmission. When shifting gears, the load on the powertrain changes, causing the engine - gearbox cluster to tend to shift. If the tripod is damaged, this movement may become more pronounced.
Unusual vibration is not only caused by the tripod
Damaged tripods do not always cause serious accidents immediately. However, if continuing to use them when this part is degraded, vibration transmitted into the cabin may increase, affecting comfort when operating, and in serious cases, it may affect related details.
Caution, vibration when decompressing, vibration when starting or noise when moving D/R may also be related to engine dysfunction, spark plugs, ignition shafts, fuel systems, air intake systems, gearboxes or powertrains.
Therefore, technicians need to directly check the rubber condition, rutting, deformation, leakage in the hydraulic tripod and abnormal movement of the engine - gearbox cluster.
Lifespan depends on usage conditions
The tripod is a wear detail but there is no fixed time frame applied to all models. Durability depends on design, component quality, road conditions, temperature, oil or chemical exposure and operation. Replacement should be based on the actual condition of the component and the manufacturer's recommendations.
When the tripod is damaged, the common solution is to replace it with suitable components. This work may require lifting equipment or specialized tools to support and hold the engine - gearbox assembly during dismantling, depending on the design of each car model. Therefore, the time and cost of repair are also different between car models.
