First you need to find out what is doing what.
I am assuming 93 is a dual latch ( left and right )
Set the lift gate down but do not latch it.
Press gently on one side or the other like you are trying to push it shut.
You should feel no major drag or resistance.
Usually, but not always, one side will feel better than another.
Obviously, just deal with the good side.
A careful eye can observe if it is draging down or up.
Loosen the striker bolts slightly and tap accordingly with a medium to light hammer.
Once you get smooth operation, your up and down is good, your in and out may need to be adjusted. Remember these latches are two stage. Meaning two clicks to full latch. Again lightly by hand, one side at a time, click once, click twice. It should require not much of a push to get two clicks. If you can not get two clicks, you need to move the striker out a bit. Do all these adjustments in small incraments.
When you get to two clicks, crawl inside with the door shut and make sure the deck lid is pressing on the seal about 1/4 inch ( give or take ) If you have that, you are golden. If you have more than that your lift gate will be tough to shut, and POP when opening. Less than that and you might get air and water leaks.
It will take some tweaking and fine tuning. It is not a quick easy task as much as slow and tedious.
Take your time. Do slow adjustments one side at a time.
having nicley lubed latches also will make a diferance.
