Hi All
As previous post's have gone knocking and creakig when turning braking etc.
I took my wheels off this weekend to paint my calipers, and found that the guide screws that go through the disc into the wheel hub are missing, meaning that the studs that hold the wheel in place knock (you can hold them and move them back and forth) so that would mean that when braking the disk stops then the hub catches up with it then knocks, (creaks inside the cabin)
Don't know if this is the case with all Lexus but am pretty sure its the case with mine.
