Idler question
Hi guys
Quick question, I can hear a hum from my idler pulley on the passenger side. I am going to replace ASAP but should I do the tensioner and the other idler as well?
I now have 270,000 miles on my 97 E-150 5.4L

I'd definitely swap out the tensioner too---have seen them for $20 new before but I'd opt for something better, OEM or NAPA or any good brand name.
Probably needless to recommend replacing the belt too---not quite "cheap" at $50 something but since you're already in there anyway..........!

I don't think the pulley is available separately from the tensioner.
With the belt removed maybe turn each idler pulley as well as the alternator and tensioner too----anything wearing out should present itself by feel or a noise you can hear.
Were it me I'd just swap the entire tensioner. This way I'd know it was more likely to hold tension and not be an issue for a while yet. If the existing 270K miles is on the OEM tensioner I'd say that's quite a run, not a bit shocked it might be in need of a new on now.
