Before working on the rear engine mount, lift the car using a hoist and use a transmission jack to raise the rear transmission and engine slightly. Take out the rear mount through-bolt and nut, remove the U-shaped bracket from the frame crossmember and get rid of the insulator on the bracket. After that, remove the rear engine support from the underside of the transmission extension housing. While installing, join the rear engine support to the transmission extension housing at its bottom and tighten the bolts to 68 Nm (50 ft. lbs.) of torque. Clamp the insulator over the U-shaped bracket and turn the nuts until the torque is 41 Nm (30 ft. lbs.). Pass the bolt with a nut through the insulator and U-bracket assembly together with the rear engine support, then tighten the nut to 68 Nm (50 ft. lbs.). Reconnect the U-shaped bracket to the crossmember and fasten it with 41 Nm (30 ft. lbs.) torque. Now, remove the transmission jack so the car can be lowered below.
