Was driving to work friday morning when trying to accelerate from a stop light heard a clunk in the rear end and felt like a loss of power when going. Above 30-35mph car was shaking like driving on flat tires. Pulled over and shifted into park another loud clunk from the rear, shift to reverse same issue and to drive same issue. Had car towed to dealership and am waiting for their response, any ideas of the issue in the meantime? FYI, car only has 25K miles

Won't have an update until Monday as they couldn't get to it yet. Tow truck driver thought it might be the universals, as he could hear and feel the clunking in the rear. It's definitely something in the rear diff that has screwed up which shouldn't be happening with only 25k miles. Question, would having a tune and disabling MDS have an effect on this? I've seen many people with tunes, diablosport specifically, and never heard of any issues. Just trying to figure out what the hell could be wrong while waiting to hear from the dealership.

I doubt the tune had anything to do with it but did you remove it before it went back to the dealer? If not they may give you some grief or if they flash your pcm you'll need to have your tuner unlocked before you can reinstall the tune.

Did not have a chance to remove the tune before I had it towed there as my tuner was at home. But they know I have a tune and they have been a pretty cool dealership about it. I've told them not to flash my PCM and the tech goes, you got a tune on there, I said I can neither confirm or deny that, to which he starts laughing and says gotcha. Yeah I didn't think the tune would have but did had to ask.

Sounds like you have a mod friendly dealer! Some are not so lucky!

JMO--might be loose or missing bolts in the driveshaft/differential coupler. Hope that's all it is. Good luck.

Just got a call from the dealership, problem is broken driveshaft bolts. Said they are on order will take 3 days to get in then they'll check everything out to make sure nothing else is wrong. Anything I should make sure they check or any other problems that can result from the broken bolts?

Good to hear they figured it out. And good thing you reacted to the strange noise and didn't just keep on driving it like some people do, could have been bad news if driven much further like that.

Not sure what else could give you problems. I'd wait and see how the car drives once you get it back, might be all it needed. Sounded like you reacted to the issue pretty quickly, so hopefully nothing else got jacked up from the bolts being broken.

 

[RWB44]

Yeah I contemplated driving it to the dealership but the way it was clunking and shaking I was like F that lol. Trying to get them to install the SRT bolts instead of the same RT ones that will break again, will keep the thread posted.

I doubt you can expect it again if like for like bolts are used. Sounds like you had a defective bolt and then caused stress on the others. That is unless there is an underlying issue that caused it to begin with.

I'm unsure about that seeing how others have had the same problem too unless it was just a bad manufacturing batch Dodge received. My problem is who's to say this doesn't happen again in another 25k and then it comes out of my pocket, not that it's a terribly expense fix but if it were to screw up the driveshaft or something else.
