2020 RAM1500 rear differential drive shaft issues

[1791]

Hi gents. I had this same issue and found there was a TSB that was released that solved the clanking. The yoke had to be taken off an greased. https://static.nhtsa.gov/odi/tsbs/2022/MC-10225253-9999.pdf
Unfortunately about two months after that the whole rear end needed to be replaced. Not sure if they were related but it was under warranty. Sad a truck with 15k on it had these issues amongst the countless other issues I’ve had. Too bad, I love the truck but getting tired of having it in the shop all the time.

i took this from that link
"This bulletin applies to vehicles built on or before February 21, 2022 (MDH0221XX)equipped with the 6.2L V8 Supercharged Engine"
so are you saying this applies to the 5.7 and the penstar also?

I feel like this aged well. I've had 3 driveshafts replaced under warranty and the 4th is failing on my 2020 with only 42k miles.

Theybare bad, defective and the techs at my dealer know this.

The driveshaft isn't failing, it needs to be greased

Took the driveshaft out and greased it up again; the notorious bump when stopping came back after about 40k miles since last time. 30 minutes in and out, done.

Grease pretty much worn away and the rear of the shaft looked dry



I did notice some wear marks that weren't there previously, I applied extra grease towards the rear of the shaft


Ready to go back in




New dust boot clamp and done

My 2024 Bighorn does it as well. Was told it’s normal on these rams. What a bunch of BS. Didn’t do it for 15000 miles when it was new
