hey guys im new to this forum and i dont know if this has been answered somewhere else. i have a 1996 ES300 with a new engine 20k miles ago =). Every Week or so the back will just start making this annoying squealing that will go away after about 20 miles of driving but then will come back eventually in about a week, i am pretty sure its coming from the read drivers side, but it is beyond me, what the heck the problem is. Thanks All, Mack
