Ok so as we all know the dreaded carrier support bearing issue (that dodge still hasn’t recalled). So I had the playing card in the bicycle tire sound for months and had no idea what it was until I saw a YouTube vid with someone w the same problem. I talked to dodge and they wanted 1600$ to REPLACE the WHOLE drive shaft just bc the bearing was “inoperable” due to it being one piece… ridiculous. So I dug into the web and found “JXB Motorsports”. A one man show that builds super quality 2 piece carrier support bearings for multiple makes/models. The 2 piece is crucial bc that’s what makes you not have to take the drive shaft out/ spend crazy $, it just clamps over the shaft. The whole reason there is a noise is bc the rubber that holds the drive shaft deteriorates and leaves a lot of play. I’ll link his site and a pic of what mine looked like before and after the shop put it on. I hope anyone dealing w this issue reads this and avoids getting screwed by dodge! Good luck!
