Mopar 4578062AC Transmission Mount Bracket

There are three power train mounts; left and right engine mounts attached to the engine block and to the subframe and a rear mount attached to the transmission and the subframe. 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. Remove the front wheels and tires. Position two jacks, one under the crank-shaft pulley and the other under the transmission bell housing. Place a block of wood between the jack head and the crankshaft pulley or bellhousing, then carefully raise the engine/transmission just enough to take the weight off the mounts. Check the mounts to see if the rubber is cracked, hardened or separated from the metal plates. Sometimes the rubber will split right down the center. Check for relative movement between the mount plates and the engine or subframe (use a large screwdriver or pry bar to attempt to move the mounts). If movement is noted, lower the engine and tighten the mount fasteners. Rubber preservative should be applied to the mounts to slow deterioration. Disconnect the cable from the negative terminal of the battery then raise the vehicle and support it securely on jack stands. Remove the middle engine splash shield. Remove the nuts holding the engine mounts to the sub frame. 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 sub frame. Remove the engine mount heat shield. Remove the bolts holding the engine mount to the frame. Remove the engine mount and replace it with the new one. Tighten the upper bolts to the torque. Lower the engine and install the engine mount nuts and torque them to the specifications.

Raise the vehicle and support it securely on jackstands. Insert a large screwdriver or prybar into the space between the transmission extension housing and the crossmember and try to pry the transmission up slightly to check the transmission mount. The transmission should not move much at all and the rubber in the center of the mount should fully insulate the center of the mount from the mount bracket around it. To replace, support the transmission with a jack, remove the bolts attaching the crossmember to the chassis and mount and the bolts attaching the mount to the transmission. Raise the transmission slightly with the jack and remove the mount. Installation is the reverse of the removal procedure. Be sure to tighten all fasteners to the Specifications.

There are three powertrain mounts; the left and right ones attach to the engine block, subframe and the engine block while a rear one is attached to the transmission and the frame. During testing, the mounts must have no weight on them so that the engine should be slightly lifted. Raise vehicle and secure it with jack stands then place a jack under engine oil pan. Place a huge wood block between jack head and oil pan, then lift up carefully just enough to remove weight from mount. Look for cracked or hardened rubber or separation of rubber from metal center in mount insulators. Check for movement between mount and engine or subframe. Make use of large screwdriver or prybar to see if those mounts can move. Lower engine if movement is detected, then tighten mount fasteners.Disconnect cable from negative terminal of battery for replacement.Raise vehicle and support it securely on jackstands (if not already done).Position a jack under the engine oil pan.Place a large wood block between the jack head and the oil pan.If you're taking out right side mount (which includes alternator support bracket), disconnect alternator support bracket.Remove nuts securing subframe to engine mount and raise engine by using this jack.Remove bolts holding mounting bracket to motor.Align new mount correctly in bracket before installing.Securely tighten fasteners after they've been installed.
