    Found this on youtube



    There is a guy in the Hellcat facebook group that was able to take apart the snout and replace the bearings but said they were not a normal bearing you can buy over the counter. Asked him for pics and more info and he is working on it. He said he needed a press and a lot of patience as it was time consuming. He went on to say

    i am no mechanic, but i see alot of posts of people getting new superchargers, has dodge came out with a reason as to why the superchargers are failing? i understand we know the bearings are failing, and if what this guy says is true about the bolt backing out then why does dodge not do a recall to fix the issue before they have to pay for a whole new supercharger? Also if they are not doing anything other then just replacing the supercharger with out locating the issue then the new supercharger as well may be screwed up...

    i am sure this has been discussed at length, i am not afraid to buy a 2016 as i know that it will be taken care of no matter what happens. but it looks like i may be getting a 2017 by the time i am ready to buy.

    No they aren't telling us anything and those explanations do make sense. Hopefully he sends me photos so we can take a closer look

    Glad to see this video. Wonder how many miles. seemed like there was a decent amount of soot, some of which was in the internal intercooler core.

    My guess is when a dealer replaces a supercharger on a customer's car, they send the old blower back to FCA, who then rebuilds it with better bearings and puts it on another car.

    FCA probably returns to IHI as a warranty claim, they then rebuild and ship it back.

    Guys, as I've said before the problem is the rear bearings not the ones in the inlet.

    Additionally, if the rotors touch the case, they'll seize long before there is a subsequent bearing failure.

    If the shaft/rotor is vibrating in the middle, the rotors are going to hit and there is going to be a lot more noise than a whine.

    And still, we have no confirmation from FCA that any of the bearings were bad

    Do you still believe there is no evidence that the bearing noise will lead to failure and that it is just an undesirable noise?

    Yes. Still no evidence to the contrary.

    What we've seen even contradicts this "new theory".

    This is the only bolt I see in the snout that could possibly have any effect on the blower, but I don't see how it could push the rotors into hitting the case.

    It can't. No way those screws are hitting anything.

    I think what a lot of people do not understand about blowers is that if the rotors hit the case or each other the noise will be huge and the damage will be significant. Tolerance for a supercharger is very tight. The picture out there of the meth injected one is not far off what would happen if the rotors hit the case or each other. Unfortunately most people have no experience with blowers and through no fault of their own do not understand their internal operation.
