Have the same problem (i think) with a 2005 LX 470. Has anyone heard more on this? I hear a sound (like a poping sound) from under the driver's left foot area when starting to move from a full stop and at low speed turns. The noise almost always is in a set of 2 or 3 pops with about one/two second in between each pop. It is easily reproduced by veering to right/left at low speeds. Thanks!
