Tensoner Pulley

[BeauxPete]

The lower tensoner pully is starting to make some noise on my truck and getting ready to replace it. Has anybody else had issues with this and did you replace back with OEM or something else. Thanks

I did. It made a chirping noise and wiped out 2 alternators, one of them were brand new.
I told ford and they ignored it the first time.
I don't think there is anything out there other then stock?

Edit... My bad, mine was idler pulley

 

[BeauxPete]

i meant the idler pulley..

 

[BFT]

Do you have dual alternators?

 

[BeauxPete]

no I have the single. I just went and checked again. I believe it is the lower tensioner pulley according to diagrams. It has the chirping sound you are talking about.
