2010 SE AT Crew w/ 6K miles. Since about 2000 miles, I've felt what feels like slop in the driveline. When I come to a stop and take off again, there's a bump that is easily reproduceable at each stop. I haven't worried about it too much, but it is annoying for a new vehicle. I had this problem with my wife's V8 4Runner, but that was solved by lubing or greasing the "propeller shaft". Any ideas on fixing this for my Fronty? Or, am I seeing the beginning of what could be a long and painful series of visits to the dealer, arguments, etc.....? Thanks!
