Anyone else having this annoying squeek behind the drivers seat? Ive checked it thouroughly, and nothing is loose, just the expected amount of play where the lever hook catches the latch on the bed. I noticed there was a dollop of factory grease on the latch, most of which has been washed off while de-mudding the unit. I put another smear of grease on it, and that has helped, but seems like there needs to be a better solution! Any thoughs?
