Stick Jams Attempting to Roll to Port

Pretty much since I have had my X52 Pro, the stick has jammed when attempting to roll to port. It will move a tiny distance.. and then no further unless I either apply far more force than I am comfortable with to drive it the rest of the way or let up, wiggle it a while, and then try again.

This happens very often, so it's not an issue I can simply resolve by wiggling it a bit before use. I can't find any information on similar problems, and it doesn't happen when trying to roll to starboard.

Does anyone have any suggestiongs?
