Squeaky Pulleys

Hey everyone,

since it has gotten a bit cooler, upon start-up my car makes a squeaky sound as the belt runs around the pulleys...

any idea what causes this @ 13k miles??

can i just fix this by spraying some WD40 on the pulley bearings??

def don't want to go to the dealer here in SB...will have to wait till turkey day to go to Indy and have a proper fix

thanks for ur input

Under warranty let the dealers handle it. Why put lube on it? If your lube ends up making it worse they'll put the blame on you and void your warranty.
