Hi,
I've had this for a couple of months now. It's gotten worse since it started, but Toyota don't seem to be able to find the reason for it.
It's mostly hearable when standing still and turning the wheels, but also going at slow speed, especially when the weight balance is moved like when going over a bump, a side curb or when the road changes from slight uphill to downhill.
It also becomes very noticeable when driving over cobblestone. In this case I can also feel it in the steering wheel. Normally however, the steering feels tight and perfect.
A local non-Toyota mechanic guesses it's a defect top strut bearing. What do you guys think?
You can listen to several videos here.
Cheers,
Casper
