How to find a bad bearing on a belt tensioner or idler pulley-2023-11-02  

I could hear the difference after you changed that . Good job I’ll have to try that next time with one of those heat temp guns

My truck is making that noise. At least know I know what that is. Thank you I’ll take it to the shop I’m not mechanically inclined lol

If you do it old school you just touch the bolt head that holds the idler or tensioner on .don’t actually touch the pulley
