I've noticed a few questions along the lines of "What could [noise x] mean?" or "How can I fix [noise y]?". As this is a site dedicated to motor vehicle mechanical issues, I expect this will be a common theme in some questions here. Should we create a tag or tags for these?
Some example threads are below. (Some may be better examples than others.):
My Car Squeals When Braking Even Though I've Had My Front Rotors Machined and Back Rotors Replaced and all new brake pads. What could it be?
Steering wheel gives a "cluck" sound
What could cause an engine to make a chirping sound when it's first started up?
How do I silence squeaky springs on a 2006 VW Golf?
2008 Jeep Wrangler - Suspension squeaks
Is there a general fix or product I can buy to silence a squeaky belt?
High-pitched squealing coming from engine
If we do want to create tags for these particular types of questions, should we create one generic noise tag, or several different tags for types of noises like squeal, clunk, chirp, squeak, etc.?
EDIT: Possible alternative to noise which can also be taken as a synonym for spam or other unwanted content, would be noises.
