by squeezing it together does that fix the problem completely or is it just worth buying new ones. also can i just take some of a old car which are fine?The Door Strap clicking is a common problem on a lot of two door cars (heavier doors). The cause of it is the weight of the door pushing down on the strap, forcing it to create a small gap on the hinge part connected to the chassis.... and if you watch it closely, you will see it popping up (clicking) as you open and close the door.
You can either replace them (not easy on the ALFA 147) or as i have done.... undo the bolts from the chassis side, and swing the door open. Then get right in there with a set of mole grips and squeeze it together. Then just bolt it back on, and give it a good grease.
