I will tell you how I cut the annoying sound in an overly practical way, even though it doesn't bother me when you put your arm in the armrest at 407 or flex on the flex. First of all, we lift the armrest, there are 4 screws under it and the armrest comes out when you remove them. Afterwards, there are 4 screws holding the upper part with the upper part where the sound comes from, and then they are separated after removing them. We fold the dried 3 or 4 wet wipes into 3, as shown in these pictures, and put them there (especially to the projections) and close them back. The process is okay, preferably the sponge can be put in. I found such a solution because I could not find it at that moment and there was no sound left.
