Mopar 4578051AB Bracket-Engine Mount

You can Select Your Vehicle to check if 4578051AB fits your vehicle.

During the mount inspection, check the mount insulators for any signs of rubber being cracked, hardened, or separated from the metal in the center of the mount. Also, check for relative movement between the mount and the engine or subframe.

Raise the engine with a jack and block of wood under the oil pan until the engine mount studs clear the engine bracket and the subframe.

There are three powertrain mounts in this system. There are left and right engine mounts attached to the engine block and the subframe, and a rear mount attached to the transmission and the frame.

Remove the bolts holding the engine mount to the frame.

For replacement, follow these steps: Disconnect the cable from the negative terminal of the battery. Raise the vehicle and support it securely on jackstands (if not already done). Position a jack under the engine oil pan with a large wood block between the jack head and the oil pan. If you're removing the right side engine mount, remove the alternator support bracket. Remove the engine mount-to-subframe nuts and raise the engine with the jack. Remove the mount-to-engine bracket bolts. Install the new mount, making sure it is correctly positioned in the bracket. Install the fasteners and tighten them securely.

Remove the engine mount heat shield.
