The "buje " these do not see, single sides at first the part of down that this nailed to "parilla", sees clearly single when low all "parilla" (that is a great work), which can do is to raise the car and and move the "parilla" with a small bar to see if the bushing is broken (the rubber) or if listening the noise (cloc-cloc) when "parilla" moves.
Also to change these bushings you need a hidraulica press, because they go nailed to "parilla".
I enclose a grafic to you of the original manual of Renault so that you see the "buje" and the "parilla" or cradle of motor , see the "buje " dont exist with number part for renault because is part of the "parilla"
I tell You that I was eight months to find and solution this noise.
Good Luck
