A friend’s 2008 Jeep Compass with the 2.4L engine was making a whining noise and the shop wanted $350 – $400 dollars to replace the alternator. They did not …

GATES: Alternator Decoupler Pulley – How to Inspect and Replace (short
version)
Thank you for taking time to make this video.
so how much did u charge them
Thanks for the video. At first I was critical of your presentation but the
bottom line was, your information was very helpful.
Great video! It will definitely help if/when I go to replace this part.
I do have one question: Is it possible that this pulley problem might
affect the alternator’s ability to keep the battery charged enough to
handle normal operating loads?
so if the car is running fine except the noise/whinning you think the
alternator is still good?
Wow, good call. Well done!
so it seems that dealerships say replace the alternator too because of the
debri that can/has from the bad pulley.
Awesome job and explanation! I have to do this to my 2007 Compass very
soon. It’s very loud and rattling. Thanks again.
They went to several places, including some off the beaten path. The
problem was none of them dug into the issue deep enough to determine
whether they could just replace the pulley. Besides, most shops will tell
you that if the pulley is bad, the rest of the alternator can’t be too far
behind. A case can be made for that argument, but best not to just assume
that but take the alternator out and actually verify suitability for
further use before recommending replacement.
Do many cars have the overrunning decoupler? Seems like a good idea, the
alternator does not have to slow down every time the transmission upshifts.
Nice of you to help your friend…. Hope you got a steak dinner or an arbys
roast beef for your efforts!
Mechanics trying to sell more than is needed as usual, did they take the
car to the dealer? Dealers have a great tendency of doing that.
Thanks! Well, no steak dinner but that’s okay. I got something much better:
The good feeling of helping a couple that was backed into a corner with few
options. They have two small children with a third on the way and the
husband’s going on deployment for ten months. They needed every bit of the
money I was able to save them. Plus, I got a good education in the process
and (hopefully) a good video that may help someone else with the same
issue. So a win-win for everyone. 🙂
Thanks
You seem like a proper nice guy 🙂
Your too generous…
More and more automakers are using these pulleys to address NVH concerns
from the belt drive system, but it’s debatable whether the NVH reduction is
worth the apparent reduction in reliability. Time will tell if this failure
was the result of a bad batch of OAD’s, or if the failure was inherent in
the design. I tend to think it was likely due to a bad run of OAD’s (wrong
grease) during manufacture.
where are u located mr.shadow rider460??
