Residue on the rear liftgate strut (Fig. 8) of some 2018-2020 Enclave, Traverse; 2020-2022 Acadia, XT5 and XT6 models is not a fluid leak that requires strut replacement. The residue is typically extra padded grease from the boot that is used to help reduce noise from movement of the strut during operation.

In some cases, the residue may be mistaken as a leak of hydraulic fluid that would assist with the pressure of the actuator. The rear liftgate struts on these models do not contain any fluid for their mechanical functionality. The residue on the struts does not affect the operation of the parts. Any extra grease seen on the struts has simply worked its way out due to added pressure on the boot. (Fig. 9)

If there is any residue found on the rear liftgate strut, clean the strut with a damp cloth. (Fig. 10) Dry the strut before closing the liftgate. No parts are required for this repair.
