Owners of other Mitsubishi vehicles such as the Outlander Sport, Eclipse Cross, Mirage, Mirage G4, Lancer, ASX, Montero Sport, Pajero, Xpander, Strada and RVR may also find these DIY instructions to be helpful.

The OEM (original equipment manufacturer) part numbers are as follows: Driver (Left) Side # 5802A781 and Passenger (Right) Side # 5802A782.

The only tool needed to release and replace the tailgate support struts is either a flat head screwdriver or a small plastic pry bar tool.

Please verify the correct replacement part numbers for your SUV before ordering the struts. The part numbers may vary depending on the model year, trim level, your region of the world and whether the vehicle has the power tailgate option or the standard manually operated tailgate.

The first two steps are to open the tailgate door for the cargo area and move to the side of the vehicle with the weak or faulty lift strut.

Have an assistant hold the tailgate door open with both hands to make sure it doesn't fall down and injure you when the first strut is detached.

Locate the small slot or notch on the metal "C" shaped retaining clip at the bottom of the support strut.

Carefully insert the blade of the plastic pry bar tool or a flat head screwdriver into the notch on the outer edge of the "C" shaped retaining clip.

You don't need to fully remove the clip, but it doesn't matter if it pops out entirely.

Warning: Make sure your assistant is securely holding the tailgate door open!

While holding the clip partially out, pull the ball socket at the bottom of the strut off the corresponding ball mount.

Insert the screwdriver into the notch and gently pry out the "C" clip.

Pull the top socket off the ball mount attached to the tailgate door.

The OEM (original equipment manufacturer) part numbers are as follows: Driver (Left) Side # 5802A781 and Passenger (Right) Side # 5802A782.

The old Mitsubishi cross reference part numbers for the tailgate  include 5802A507, 5802A601 and 5802A769.

Partially remove the "C" clip at the top of the strut and push the socket over the ball mount attached to the tailgate door.

Push in the back side of the "C" clip to make sure it is fully locked in place.

Line up the bottom socket with its corresponding ball mount.

Push on the back side of the "C" clip to make sure it is fully locked in place.

Double check that both of the "C" shaped retaining clips are secure before moving on to the next steps.

Once you are certain that the tailgate is securely supported by the new lift strut, allow your assistant to let go of the tailgate door.

Test the new strut by carefully opening and closing the tailgate a few times.

Don't forget to write down the procedure in your vehicle's service records.
