I took my LR4 on a Home Depot run the other day only to find out in the parking lot that the tailgate wouldn't open. Luckily it did eventually open but that was a warning I needed to replace the actuator. So, here's a write-up. Please note that this is on a truck where it only failed to open once. If you let it go, the actuator may fail completely and you're in a world of trouble trying to get the lower carpet off to open the door.
Tools Needed:
T30
T20
8mm
10mm (if using Genuine updated actuator)
13mm long
Plastic trim tools
Phillips screw driver
Flathead screw driver
Small pick
Removal:
1. Open the door. If the actuator is weak, try using the key and gently pressing in on the upper tailgate near the hatch latch in the center of the door. I tried a couple times, let it sit, and then tried another three before it opened.
2. Remove the four screw covers on the upper trim of the tail gate and remove the phillips head screws.
3. Remove the upper trim by pulling up or prying gently from the inside with the trim tools. It's held in by the metal screw clips and two plastic retainers. I used a screw to realign the screw clips for easy installation when it's time.
4. Support the tailgate on something and remove the tailgate cables. I used a tall box with some bubble wrap. Make sure to slide the pop-collars on the cables down toward the truck before popping them off the nipples. DO NOT LET THE CABLES GO. I just gently let them feed against the trim panels, but you could use a bag clip or cable holder to keep them from going up into the truck. The nipples on the tailgate are 13mm.
5. Remove the lower trim panel. It is held in by plastic retainers. Just use a trim tool and work your way around the panel.
6. Remove the T30 screws securing the hatch release. There is no adjustment on it, so you don't need to mark them.
7. Remove the tailgate actuator. You'll need to remove the two 8mm bolts holding it to the tailgate and unplug two tabbed connectors. you can prop the folding trim up and out of the way with a large trim tool. One connector goes to the actuator on the RH side of the tailgate. The other goes to the hatch release in the center of the tailgate. You'll need to break into the foam cover. I have tried heat guns on these before with no success. Just get in there.
