When driving the 2014 Pathfinder with the 4wd not engaged sometimes at low speeds when turning it feels like something in the back is dragging. It only seems to happen when going low speeds and turning and to make it worse it doesn't do it all of the time. I have recently replaced both rear wheel bearings and abs sensors in the back because of the abs light being on. The abs light is no longer on but I have this weird behavior. I was thinking maybe a rear caliper was binding up or a brake hose collapsing. Someone mentioned to me that it may be something in the rear differential binding up but I thought they are free spinning unless the 4wd was engaged. If anyone could please share your thoughts on what I can check to try and diagnose this issue. I have only had it for a year now and I have no idea if the rear differential fluid has ever been changed. The Pathfinder has 80k miles.
