Thanks a lot, Admin, for providing the part numbers.
Are these two parts for left and right front doors?
I went to Lexus of Cerritos (CA) yesterday for my 1km check and told them about this problem. Their mechanic test drove the car himself and reported not hearing any abnormal noise. I drove a round with him trying to "show" him the problem; he still couldn't tell any difference. These part numbers will definitely shut them up, I hope.
