How to Service and Repair a Rear Engine Mount on 2006 Jeep Liberty?

Before repairing or servicing the rear engine mount, first take out the negative cable from the battery and raise the vehicle up to support the transmission. Undo the nuts connecting the support cushion to the crossmember and remove the crossmember. With the vehicle's manual transmission, first, loosen or remove the cushion nuts and the cushion and then remove the bolts fastening the bracket to the transmission. When using an automatic transmission, lose the bolts that hold the support cushion to the transmission and then pull those parts away for 4WD or from the adaptor bracket for 2WD. For vehicles with just two traction wheels, remove the bolts that hold the transmission support adaptor bracket and pull out the bracket as well. Attach the mount (1) to the transmission, install and tighten the bolts (2), place the crossmember under the vehicle and fit the mount through bolt and nut to hold it. Screw the bolts on the crossmember-to-sill to 41 Nm (30 ft. lbs.). Then, lower the vehicle, take off the transmission support and connect the battery's negative cable back to the engine. For automatic transmission, fasten the transmission mount to the transmission with bolts, position the crossmember, remove the transmission support, bring the vehicle down on its wheels and rejoin the negative cable to the battery.
