Lift Cylinder, Rear

You need to start with supporting and opening the rear compartment before you begin. A small flat-bladed tool should be used to lift the retainer on both ends of the rear compartment strut. Push down with force when you reach the end point of the liftgate/hood rod installation to prevent accidental damage. Take the rear compartment strut off the hinges by removing it from the ball studs. Bring it out of the vehicle. Set the top and bottom of the rear compartment strut onto its ball studs on the hinge, push the bottom ball stud first and then the top into place until the hole seats completely. After those actions install the support back into its place and close the lower and upper strut retainers.

In order to replace the rear compartment lid strut, first open the rear compartment and support it. Raise the rear compartment strut retainer at the bottom and the top end using a small flat-bladed tool. Apply pressure only when one is in the final stage of removing or attaching the liftgate/hood assist rod to prevent any damage or bending. Remove one of the rear compartment strut from its position on the ball studs of the hinge and remove it from the vehicle. For installation, make sure the top and bottom of the new rear compartment strut are aligned with the ball studs on the hinge and insert it onto the upper ball stud, pushing it unto the entirety. Then, install the strut on the lower ball stud in the same way. Close the rear compartment, upper and lower strut retainers, remove the support.

Apply pressure only at the end of the liftgate/hood assist rod being removed or attached to avoid damage or bending.
