Rear end clunk

[Jasonmos]

I have a 2013 2500 tradesman. When I take off from a stop I get a clunk sound almost like there is a split second where the drive line turns before it grabs and I start going. I have also developed a squeaking sound on the front side of the differential and when I investigated that I found the diff is pretty low on oil and it's pretty thin. I'm assuming that a bearing is going bad from lack of oil and o can probably fill it with oil and that will take care of the noise. But what about the clunk. Any thoughts

Check the u-joints on the driveshaft. If one is going bad they can generate a healthy clunk. Could also be the source of the squeak you think is coming from the diff. Does sound like your diff could stand a fluid change, tho.
Best,

The clunk is “normal”. Annnoying as hell but “normal”. Heck my f150 did it too. I’ve checked everything and a;l is good. My f150 has a TSB to remove driveline and lube the drive shaft. But it comes back. There’s tons of info on the forum in this problem

I had a clunk once on a 2005 2500 and it turned out to be the spare tire not secured properly. Worth a look.

Thanks for the info. I will definitely check the spare tire

That drive shaft will carry noise from one end to the other like a string guitar... I had “Pinging” one time and swore up and down it was the drive shaft... silly U joints...
