Sweet! I filled all the subframe mounts and diff mounts with windoweld in my 300C, never had wheel hop since.
Salt does definitely suck. Glad you got to get her out and testing it out!
It was an unexpected bonus!
Whoo! I have been waiting for this video! Hats off to both of you on getting this all fixed up, it is added insurance and peace of mind for your upcoming track season. In Southern Ontario we received our first decent snowfall the other week, it has now melted and sunny and +5C is in the forecast... in January! Mine is in having body and a complete repaint done over the winter, very excited to see the outcome of that as well. I bet you are sleeping much better knowing it is back in one piece, ready for spring!
Thanks man! Yea winter delayed and then came back harsh! Are you changing your colour or just refreshing the original?
That's wicked i just parked my summer truck back in the garage right before the snow fell...and i live in Hanna ..it was nice to whip around ..just need to wash it after i pull it out again .
Nice! It’s definitely a good pick-me-up in the middle of a really long winter!
Tried to get those bushings for my 2012 rt. Manual as well. But apparently nobody makes the differential bushings for my year model. Fun stuff but I may try the 2010 bushings. I can't see a difference in them. Glad it helped you buddy. Broke my subframe the same way
Well done. Good work on the diff.
Thanks man! It was nice to be able to tackle it myself with a good buddy. 💪
I no what you mean I’m in Maryland had mine out last week 67° now there’s 11 inches of snow on the ground mines never been in the snow either. Glad your car is running real good sounds great.
Thank you sir! We’ve got to keep these cars pristine, especially if they’re not making them anymore! Winter came back with a vengeance after I shot this. Monday morning on my way to work my Jeep was reading -37. 😳
It's cool to see you've owned the car for 15 years and still get enjoyment out of it. I'm looking forward to one day getting the new body style (2015 and up) and strengthen the valvetrain and other internals to ensure the engine is bulletproof.
I’m pretty nostalgic I guess, I was extremely excited about my car when I first got it and the feeling hasn’t really faded. I really like the gauges and headlights on the 15+ cars, good luck in your search!
@TrackPackRT Thanks man. I've been watching all you've done to your car for a while. I also like that you're one of the few guys who drives a stick. I plan on getting a stick when I do find my purchase.

Living in the far deep south (USA), It is summer 10 months out of the year. I enjoy driving mine, so I get the excitement! keep it up man, glad you are back on the road
I’m jealous of you guys for that reason! Thanks man! 💪
I have a 2015 rt i did solid motor mounts and just recently purchased solid diff and subframe bushings, wish me luck on the install and NHV 😂
Haha let me know how you make out!
Did bmr cradle lock out and bmr urethane differential bushings. NVH like a mother. You can hear that differential whine now.
@@davidschlichting2191 too late for me I already bought the kit 😂 it’s gotta go in now… can I turn the music up and drown it out… is it worth the whine??? let me know if I’m making a mistaken even though im gonna install it anyways
My diff did that sound after I had a new 3.09 put in that sublime green Challenger I had. After I noticed it, it got on my nerves. The factory 3.07 didnt do that.
My buddy Matt’s 13 did it, got it replaced and it still did it. His 18’ didn’t at first but then after time started whining a little. Seems super common.
What differential do you have in that car? I have a 13 SRT8 with the 392 getrag and 6 speed. Dealer replaced it because it was clunking with loads of play. Whe I got it back it had the same play and clunk, now along with a whine. Couldn’t get them to change it again due to the expired wrt. Before a buy a new unit, do you or did you have any of those issues, especially the 50-69 MPH Whine?
Did you have to get the car aligned after installing the rear cradle? Thanks!
I wrote this comment at the 10:27 point of the video. WhenI restarted it, I heard the whine, I have the exact same noise. Wasnt there before the unit was replaced. And its much louder in thr warmer weather.
I had the same problem with my 10 R/T. They replaced the driveshaft and I think that fixed it but I can't remember for sure.
Mines a Getrag as well. I can’t remember how long it’s been whining for but it’s been awhile now. Combing through a lot of forums seeing what other people have experienced it is extremely common. I’ve heard cases like yours where they replaced the diff because of slop and clunk and the new one did the same thing. Mine was a clunky as well, and with the cam and aggressive tune it lead to an annoying bucking problem that also highlighted the clunk in a bad way. I will say though after I snapped my axle and put the new DSS ones in it dramatically improved the issue. To the point that when my wife took her first drive in the car with me she turned to me right away and said “that is so much smoother!”. If she can notice it immediately it definitely made a night and day difference.
@@TrackPackRT thanks for the reply!
The whine is more annoying than the clunk. In the cooler weather not as bad, but summertime its really loud. 25k on the clock and its like a new car. A local guy suggested Randy’s Ring and Pinion, online. I was told that these guys are the S***
Ill deal with it in the spring.
Nice job on the repair….. should get a small lift. I got a maxjax 10 years ago. Didnt think I would use it enough and havent stopped using it, mostly for my work vehicle.
Did you have any issues with alignment when you reinstalled the rear cradle?
@@cobraninetysix3883 not really, we were pretty careful to thread the bolts up evenly so one side wasn’t going in crooked which would probably put it out a little bit. I might go back in the spring to check and make sure it’s good, but we weren’t too worried about it. The test drive kind of confirmed it for me as well, it was tracking really straight even when I let go of the wheel.
What did you put for axles in your car? I have that horrible bucking problem.
Went with driveshaft shop 1400 hp axles. They made a big difference immediately in helping stop the bucking.
Did you get diff whine after doing the diff bushings?
I had the diff whine before the bushings, but it did make it louder after install. To be honest though you only really notice at highway speeds. For what it’s worth I’d still do it the same way if I was going to do it again, the car just feels so solid and responsive with all the work I’ve done to the driveline, where before it felt kind of sloppy if that makes sense.
Did you do a 1 piece driveshaft yet?
Nope! Don’t think it’s in the cards right now, this one is holding up fine. 🤞🏻
