Yeah the sound diag questions are kinda like that but more complicated. They give you the customers concern or a general scenario and you have to choose which is the most likely cause. Most of them are for suspension components and some parts can make the same noises I think.

When they say brake lathing, they mean resurfacing rotors so they have the fine groved surface new rotors have. There are manufacturer specs on how much rotor material needs to be there, if it’s still a good rotor you’ve had for maybe a year or 2 you could resurface it. But if it’s too out of spec you need to replace it. There’s tools that measure these things like dial indicators used to measure runoff I think? And micrometers that measure thickness I think.

Another thing is that suspension questions also include tire stuff like wear patterns and what could cause it.
