2009 RX 350 155k
My RX occasionally makes a rattling sound for a second or two when you first start it. Once running, very quiet, and runs
great. Could this be a dry Rod bearing, because it is in the morning, or something with the timing chain?
Stearing wheel wobbles back and forth violently at 75-80 sometimes....not when mechanic is test driving of course. Intermittent problem, does not do it all the time. This problem is
dangerous at freeway speeds. Knowledgeable mechanic has checked tie rods, axles....everything on front end appears good....need help..! Otherwise car is in very good shape.
