I just purchased a 2007 rx350 with 120k miles. Whenever I turn the steering wheel past the 1 o'clock position I hear a moderate clunk/pop noise in the front end. It makes this noise regardless of speed. No noise when going back left to 12 o'clock position but as long as I turn it back to the right past 1 o'clock it will make the noise again. Does anyone have any suggestions where I should begin to look?

Start with the axles sounds like the ujoint

Since this car is new to you take a very good look at all the rubber bits on the suspension they're likely shot (lower control arms, ball joints, sway bar links, axle boots), also inspect front struts.
