'06 Rx 400h, 80,XXX miles. I hopefully fixed the radiator leak, am going to change the oil today as well. Test driving the car last night, I noticed the steering when turned a bit to the the left, then right will have a noticeable click. It feels like a little excessive lash as if maybe the nut holding the wheel to the splined shaft worked loose. Or maybe like a universal joint bearing failed. If turning the wheel back and forth while driving it will click every time. I'm thinking this could not be an isolated instance.

We bought the car new, my wife is the driver and has noticed this too. Any ideas? TIA.
