My 2019 Ram 2500 started out as difficult to open - needed to put weight on it to get it all the way down - then it was equally difficult to close. Now its even more difficult and it looks like the the oblong pin attached to the tailgate on the passenger side is coming out of the cup thats attached to the bed frame. Ive looked online and do not see either the part attached to the tailgate or the part attached to the bed frame - anyone have a similar problem and how did you fix it.
