Ordered a new Motocraft Tensioner, pretty sure the bearing or something is going out. 100k says its about time for a new one.

Making sure I get the proper tension this time too ?

Thanks.

Recently just replace harmonic ballacer on my 2011 SE 3.5l FWD, with 117k miles. Ever since, ive noticed a click sound and a pulse of vibration along with it during idle. Sounds like its coming from the pully system. Any ideas? I think it might be the tensioner.
