Symptoms of bad motor mounts and related replacement cost

The comfort that drivers and other car occupants enjoy is a function of well-designed suspension systems and shock absorption utilities. Components like the car engine generate plenty of vibrations during operation. Failure to dampen these vibrations can make driving extremely uncomfortable. Even so, many drivers overlook motor mounts. They rarely pay attention to their quality. There is little information about motor mount costs.

Here are some signs of damaged motor mounts and related replacement costs.

What are motor mounts?

Motor/engine mounts are used to secure the engine to the vehicle’s frame. The mounts contain rubber which reduces metal-to-metal contact. Rubber absorbs a significant amount of vibrations from the engine. When the engine is running, it generates plenty of vibrations. The vibrations can be disastrous if not well contained. Motor mounts absorb these vibrations so that car occupants can enjoy a smooth and comfortable ride. The mountings also maintain the position of the engine. Once they are broken, they should be replaced as they can cause component misalignment and break some motor components.

Signs of a bad engine mount

Abnormal vibrations

A damaged motor mount cannot absorb all vibrations from the engine. When it begins failing, the engine transmits the vibrations to the vehicle’s frame. The rubber component wears out, and the engine dislocates from its desired location. The vibration can be felt in the car’s compartment.

Repeated impacts in the engine bay

Drivers begin noticing a clanking sound at the engine bay. The repeated impacts occur due to the gradual wear of the motor mounting. The engine is no longer firmly secured and moves from side to side, hitting the metallic frame.

Engine movement

Mountings are critical for securing engines in place. They hold the engine firmly to the chassis. When one of the motor mounts is broken, the engine begins moving from its original position. The movement is evident when accelerating. These movements are a safety risk to car occupants.

Slight tilting of the engine

Mountings align the engine accordingly. The engine maintains an even level. Once the mounting begins deteriorating, the engine loses its original alignment. One sign of a damaged mounting is the engine tilting in one direction. If this is not addressed early enough, the misalignment may cause damage to rotary parts.

Damaged engine block

Severe engine mount damage causes irregularities on the surface of the engine block. The broken mount will cause the engine to bounce under different driving speeds. Since the engine block is made from brittle material, it is likely to disintegrate.

Average motor mount replacement cost

If a driver notices any of the abovementioned symptoms, they should replace the motor mounts. It is a preventive measure that ensures serious car damages are averted. The cost for replacing a worn-out motor mount ranges from $250 to $600. The cost of new motor mounts is pretty affordable. The labor costs are relatively higher. The average labor cost for replacing a damaged motor mount is approximately $200-$450.


The only solution for a damaged motor mount is replacing it. Hesitating when these signs manifest means you will spend more to replace damaged engine components. Pay attention to the quality of replacement components. Do not mix aftermarket engine mounts with aftermarket alternatives.
