Nissan Maxima shaking issue after replacing motor mounts on Nissan Maxima

Some Nissan Maxima owners report experiencing persistent vibrations even after replacing motor mounts, indicating that further investigation may be necessary to identify the root cause of the shaking. After motor mount replacement, if improvements are noted but vibrations continue, owners are advised to check other components such as transmission mounts and suspension parts for wear or damage that could contribute to the issue. Common symptoms of bad motor mounts include rattling, shaking during acceleration, and clunking sounds when the engine shifts. If issues persist after replacing one motor mount, some owners recommend replacing all motor mounts, as they may be equally worn and affecting performance. Additionally, specific mounts may need replacement based on symptoms; for example, addressing a clunking noise may require replacing the passenger mount, while both front and rear mounts may need attention to improve vibrations. Some models utilize liquid mounts designed to dampen vibrations, allowing for engine movement without transferring excessive noise to the cabin. Furthermore, if a whistling noise is heard from the front motor mount, it may signal a problem that warrants inspection and possible replacement of the mount or its sensor.
