Dealer: Front CV Axle/Diff splines severely rusted

Update 3:

Sway bar replaced, clunk still there. I’ve asked them to check body mounts per TSB.

They replaced the sway bar or links?

Links.

My clunks are coming from lose brake pad…

I thought it was the axle shafts clunking?

I’ve had front brake calliper brackets replaced on both my 2020 and 2022 rebels due to a clunking noise. Mechanics had to use chassis ears both times to find the problem.

It was. They replaced it but still clunked. Not sure if it made any difference but they said it was still clunking. I’m gonna pick it up tomorrow and check the brakes

I’ve seen lots of videos regarding this and the only fix is to replace the cv axles and stub (intermediate)shafts. I suppose the rust could eventually get bad enough that the splines rust out completely and you lose 4wd as the rusted out side would just spin.

I had a cv axle replaced on my 2020 due to clunking noises and a large amount of rust. Inside the stub (intermediate) shaft to cv axle is a small spring clip and that is all that holds the cv axle onto the stub shafts on each side. If rust were to build up it might make removal of a cv axle harder or nearly impossible overtime.

I currently have a clunking noise in my front end that is usually sway bar bushings, but after replacing them for a 4th time the clunk did not go away. I am suspecting the drivers side cv to stub shaft connection as it shows signs of rust like yours aswell as a ton more play than the passenger side.

There is no grease applied to these splines from the factory, nor is there a seal to keep water/salt brine out of the connection. Poorly designed in my opinion.

I've just got mine diagnosed today and at merely 47K miles which is unacceptable! Passenger CV axle rusted, and splines damaged per the repair shop. Recommendations is to replace both CV axles and intermediate axle as well. Agreed in poorly engineering joint shaft design and shame on Chrysler (or FCA, Stellantis, whatever)!

Not far off from when the dealer replaced both front axles and the entire front differential on my 2022. Think it was right around 50k miles.

Sorry to necro an old post but any of you with trucks out of warranty get a case through Ram with these repairs? Took my truck into an independent and they identified the same CV/Front Diff play. I'm at 96K in my 2019 Rebel but they want like $4k to replace everything.

Having same issue on my 2020, rust coming from axle hubs. Dealer says they won't cover as out of warranty. The crappy part is I have 4 friends with the same truck and same issue that had theirs replaced under warrnty becuse their axles failed under warranty. All 4 happeneded between 25-30,000 miles. My truck just reached 26K, guess it sucks taht I dont drive enough within warranty time. Dealer requested good will and Ram says they will only pay 20% of part. Ridiculous.

Yeah, depending on when you bought it, you would be outside the 5 year powertrain warranty
