    So the cat just hit 12,000 miles, the other day when I was backing out of a space and turning I felt and could hear a popping sound in the front like a worn ball joint would do. I jacked it up today, wiggled the front tires to check wheel bearings, everything tight, then I pulled the front tires and checked everything. Can't find anything loose or where anything has shifted or where anything has been rubbing. Has anyone else ran into this? Any suggestions? I DO NOT want to leave this thing at a dealer for them to drive and try to diagnose until I know more about what's going on. Any help would be greatly appreciated, thanks!

    Could be rear diff fluid and the clutches.

    There is a TSB out for rear differential noise so you could have the dealer check it out under warranty. All they do is replace the rear diff fluid.

    Another option is to buy some Mopar LSD additive, add it into your rear diff, then go do figure eights. Then see if the noise is gone.

    Thank you sir, I realize now I failed to mention, it very clearly sounds as if it's coming from the front. I know sound can travel through vehicles but this sounds and feels as it a front ball joint it wore out, but I couldn't find any okay in anything today. Hmmm

    You sure it isn't the rotors clicking? You won't feel them, but you'll get a clicky clack if it is rotors. Sharp turns while backing at low speed brings it out.

    When I complained about my wheel shake at 80+, and they balanced them for the 5th time at the dealer, clacking was gone. I think they just took a wrench to everything. No mention of it on the work order. My car made noise from 0 to ~13000 miles.

    To get rid of the wheel shake, I had to get rid of all the Pirellis.

    Im seeing posts about 2 piece rotors clicking (this is not a click), I'm not quite convinced that if the rearend had something lose that the feel and sound could travel through to the front even though this is a unibody car, and this morning when I backed out I could really feel it when it did it. The car has 12000 miles on it now, I don't see how or why it would have a sudden "click" just now and never before. Ive had the tires and all off several times before, and lowered it a few thousand miles ago. If this is the rear, than fluid wont fix a "clunk", yes it will fix a whine but not an actual clunk you can feel all the way through the car. Any chance the rear has developed some play in it? I have tracked it 3 or 4 times, a few runs each time on dot drag radials, but never hit better than a 1.7 60ft, the clutch isn't strong enough for this thing to grab well enough to hurt the rear (in my opinion).

    Anybody know of any SRT certified dealers in Northern Florida?

    Somethings you just don't forget. Like where to buy cheap beer and that breakfast burrito that gave you the runs. :eek:

    Maybe possible tire skip? If your front tires are summer tires and you are low on tread while its cold out they can skip across the pavement.

    Ujoint or center carrier loose on ds? Doubt motor mount, but that is up front.

    Need a second person to eyeball it with the hood up as you shift from fwd to reverse to catch it.

    The carrier bearing seems to be a problem with the stock propeller shaft.

    Yup. I had it last week.

    Backing out, wheel half turns. A clunck, front passenger side and noticeable feedback through the steering wheel. Thought the tire skid on a rock or something but nope. Looked around under the car and at the visible parts and nada.

    That was a week ago and no repeat occurrence.

    Just once or every time? Sometimes the tires get loaded and pop if you turn and the suspension gets unloaded. Same thing happens after you jack it up sometimes.

    I remember when the Challenger first came out, many people were complaining of the very same issue. I noticed the same noise when I was backing/turning out of my driveway, but not when I was going forward.
    It turned out to be the negative camber on the front tires fighting against the tire tread. It would actually make the front tires chatter in sharp reverse turns. The problem was even worse when I bought Nitto Invo's on Viper reproduction wheels to replace the F1 Supercar tires on stock rims - they were a bit wider. Turns out friction was the culprit and there were no mechanical failures.
    Maybe this is what you're noticing?
