Noises , hard to find but there are ways .
1) take it to a garage equipped with 'mouse ears' . They get stuck on different areas and measure sound . Loudest wins
. You now know where the issue is .
2) buy an infrared thermometer and look for hot spots on anything you suspect . If bearings are an issue , lots of heat will be generated in that area .
Noises are hard to diagnose in person , it's just a guess online . These two methods will point at the problem . #2 being DIY at minimal expense is my favorite .
