2005 Model peugeot 307 models, as you know, it is known that the torsion bushing (flare) explosion that I heard is chronic. Since the cartridge was broken, I went to change it and it is 68 mm. In the next mass production, which is the original piece comes in 72.50 mm diameter difference. Since the part was faulty, Peugeot later changed production. When you entered the pit, that hitting sound disappeared with the newly installed piece. For your information, approach it accordingly. Golf 4 cartridge is fully compatible as it does not fit the original.
