If you mean the rubber boot then not in itself but if is been damaged a fair amount of time and allowed debris to enter and allowing the grease to exit then it could have caused damage to the joint.

I had one where I ignored it clicking and eventually grinding for about 6 months until it finally gave up on the motorway in the rush hour. Luckily I was nearing my exit, it was pulling right, left, up and down and all over, not a pleasant experience. They're only about 15 or £20 but can be a pain to fit depending on the car.
