Yes. That's what it does for a living.

Context clue. Hard surfaces on interfacing parts click.

If the grommets were hard enough that you determined they needed 
changing, they likely did. That doesn't mean you have to do the Corfam 
replacement for free. Clicks can and do come from more than one possible 
source. When someone shows up in the ER with appendicitis and a broken 
leg, it's not a fix one and go sort of thing. There's nothing in the 
laws of the universe preventing two or more things being wrong at the 
same time.
