07 EL..........My rear gate lift-acuator moans and groans, pretty nasty sounding. I ran it down to the top attachment point. Lubed the piviot on the plunger and the post it mounts on with no luck. Anybody had this problem??
My automatic opener/closer would moan and groan while in the closing operation, it got louder if it was hotter outside. Dealer replaced the open/close motor and and black arm thing under warranty no problems since.
