the last couple months, i've been chasing a squeak in the front of the car. the squeak changes based on rev's, thought it was a belt, changed the belt, still there.
every time i start the car, the squeak will start, and change with revs for about 15 minutes, and then dissipate. nothing catastrophic, but irritating trying to quietly leave my subdivision...
today, finally tried checking pulley's. one is barely noisy, but i think i found the unexpected cause. looks like the 2 stamped steel idler pulley mounting points protrude enough to rub on the bearing retainer collars.
my suspicion is that the plastic rubbing off on the mounting point is the cause of my noise. side-benefit, one of these pulley's is the one that's slightly noisier.
so the question is, does anyone know if the idler pulley design was revised in the 2015+ updates? while i'm inclined to replace them with new, if the design remains the same, the new pulley's are going to suffer a similar fate...
is anyone else aware of a similar wear pattern in other '13-15 cars?
is it worth clearancing this area myself? the mounts are integral to the block, which i've got no intention to replace anytime soon, so i'd rather not mess up the block if i don't have to!
