Rear end? Sound
Have a 2022 f350 cc srw with 3.73 rear end. Put 285/75/18 open country r/t trails at about 400 miles with 2” level. Noticed since the new tires (really noticed in last 500-700 miles now at about 1700 miles total on truck) I have a low oscillating sound that seems to come from the rear end. It is most noticeable at about 48-53 mph and is distinct from road noise of tires. I cannot duplicate the sound outside of overdrive gears (9/10) with 9th being the loudest. Seems to go away at 55+ but wouldn’t swear that it totally goes away. The sound is hard to describe but is kind of a repetitive low “womp-womp” type noise. Most noticeable at lower rpm say about 1100-1300. Have taken back to tire shop and they balanced tires again. Do not think it is tires as it does not make the noise except in 9/10 gears. If I lockout the 9th and 10th gears and run the same speeds in 8th, I do not hear it. Not trying to make a big deal out of nothing but the sound annoys me and more importantly I’m concerned something may be up with transmission or rear end. No heavy clunking/grinding sounds or hard shifts that I’ve noticed. Anybody got an idea on this one?

I actually traded the truck in last July on a 2024. Never got worse or better. Had about 20k miles when I traded. Incidentally my 2024 which is a lariat gasser has never had this issue with 14k miles and counting. Hope this helps
