    Although I loathe taking her service, the rear end whine at 65-75mph was getting a little annoying. Maybe it's the nature of the beast, and then so be it. But I just need to know. I'll post with results.

    Ok service diagnosis is in: Noise not coming from the rear end. It is resonance from the supercharger being heard through the exhaust. Of course, skeptical me needed proof so I took the shop foreman for a ride and he confirmed it. Yes, it does get louder under load he said. He's heard a few like this. He also put it on the lift and did the stethoscope thing. Rear end quiet.

    Good enough for me. I guess i have to take their word. I have 7/100 Warranty so if she blows I get a new one.

    Yea I was surprised. I thought for sure rear end noise. Still skeptical. I'm going for a 2nd opinion. Nothing else better to do with my time :-(

    Good to hear. I have heard others complaining about this noise.

    I don't have any rear end whine but I love that SC whine. I think some may be confused because they aren't used to hearing it.

    I'd be looking for a second opinion as well. I had my Ram in the shop 4-5 times looking for a rattle that I went into saying was the steering intermediate shaft..Had the same issue on a previous truck. They swore that wasn't the issue and replaced something every trip in but it still rattled. Finally a set of "chassis ears" was ordered and it was confirmed to be the intermediate shaft. Not saying your dealer sucks as badly as mine but double checking their work is a good idea.

    How can they replicate the noise on a lift with no load? IMO, Chassis Ear is best way to pinpoint the source of driveline noises.

    He may have used the chassis ear. But you are correct without load it would be useless.

    Also, look at the gap between left rear tire and wheel well for rubbing. A few others here have had the same issue due to deform in plastic mold or warp. Check it out. I had left side gap of less than 1/8" and the right side 1/2"+.

    I took this photo behind the driver side rear tire. Notice how close the plastic wheel well cover is to the tire? This is what is causing most of the driver side noise many Hellcat owners are hearing. The plastic has been gradually warping from the heat of the exhaust. I opened a case with SRT and hopefully they will have a quick resolution. Does anyone else have this same problem?

    I posted a similar picture a couple days ago for another member. I reshaped the area and it's all good. See the a IMG_0011.JPG fter reshaping below.

    SRT opened a service ticket on this issue. Hopefully they will redesign the wheel well and get the new part to the dealers and on the assembly line. I'll post any information I obtain and share it.
