Today I raised the passenger side rear seat in my crew cab but when I went to let it back down it clunked and stopped a couple inches from the up position. I reached under to see if there were any latches or anything out of place, but found no reason for not lowering. I checked the position of the seat back while I was lowering the bottom but seemed normal. I repeated the process quite a few times before it finally didn't clunk and lowered. Has anyone experienced this?
