    Thank you! Thanks to a youtube video I replaced the serpentine belt on my Jeep Liberty by myself for $41.00. I am now headed back to the parts store for an idler pulley and a tensioner pulley for around a total of $34.00. The dealer was going to charge around $400! And, did I mention, that I am a girl?! 😉

    I have purchased a new idler pulley and about to install with help from your video.
    Question tho: you mentioned cold mornings, did you have a 1-2sec loud whine from this also but only on cold cold mornings? I only get this when its below 10F. Wondering if it's also from the idler bearing. Thanks for creating this video!

    Finally had enough of the loud squeaking and being embarrassed at the stoplight . And today was a perfect 38° Minnesota weather to do it. I only replaced the tensioner pulley and now my jeep sounds beautiful. Thank you!

    You can easily change the bearing in the idler pulley without replacing the whole part. Also there is a metal tensioner pulley Dayco 89051 – after installing it youl`ll also need to change only bearing in the future.
