Toyota 12371-65010 Insulator, Engine Mounting, Rear

Engine mounts seldom require attention, but broken or deteriorated mounts should be replaced immediately to prevent added strain on driveline components that may cause damage or wear. During the check, the engine must be raised slightly to remove the weight from the mounts. Raise the vehicle and support it securely on jackstands, then position a jack under the engine oil pan with a large wood block between the jack head and the oil pan, carefully raising the engine just enough to take the weight off the mounts while avoiding the drain plug. Inspect the mounts for any cracks, hardened rubber, or separation from the metal plates, noting that the rubber may split down the center. Check for relative movement between the mount plates and the engine or frame using a large screwdriver or pry bar; if movement is noted, lower the engine and tighten the mount fasteners. Applying rubber preservative can help slow deterioration. To replace a mount, disconnect the negative battery cable, raise the vehicle, and support it securely on jackstands while supporting the engine. Remove the fasteners, raise the engine, and detach the mount. Installation involves reversing the removal process, using thread locking compound on the mount bolts or nuts, and ensuring they are tightened securely.
