Broken Weld on DPF Bracket

[Lookthermo]

Today a rattle appeared at idle. After it driving me crazy all day and a little investigation I found a bracket that is welded to the DPF and connects to the transmission. This bracket has completely broken away from it's weld on the DPF therfore the rattling. I'm going in for service this saturday for oil change and tire rotation. I'll mention it to the dealer but my assumption is they aren't going to weld it back in place. I'll also assume that they will probably want to replace the whole DPF and won't have it in stock. This doesn't appear to be a major issue just more of an annoyance. Just figured I'd put it out here in case anyone else has experienced this rattle.

I had the same issue after some light off-roading, took it to the dealer and they did a tap weld. Hopefully this is not a common issue!

the Jeep is telling you it wants to be freed from its oppressive government mandated muffler bearing system

UPDATE: Took it in to the dealership for an oil change and mentioned the rattle. Dealer had the bracket welded back and the now I have no more rattle. That was easier than I expected!

The noise was driving me crazy....

There is another post in regards to the same issue.

I just wanted to update others running into this issue. After my second trip into the shop for service, they found the exact same broken weld. I believe this is an going to be an issue with the Ecodiesels. My dealer took the bracket off and told me they are waiting for FMC to tell them what needs to be done. I have a feeling there may be a service notice and/or recall on this moving forward. Seems like too many of us our running into the same issues.

Good luck and happy trails.........

My dealer said it was caused by the lift. Said there should have been an extension. I asked him to show me the extension on the mopar kit and he couldn’t. Nothing in this area looks to be impacted by any part of the lift.

Yeah, so that tech/service manager needs to show all of us how the exhaust is connected to the suspension. OMG....what a moron....

UPDATE 2: The weld broke again after the dealer had welded it. I brought it back and spoke with the service manger. He decided not to mess with it any longer. He agreed to replace the DPF under warranty. The new DPF has been installed and so far no issues. I can only assume Jeep has made a change to the part because the part number ended with a letter higher than the original one.

Just posted on another thread. Same thing here, getting a new DPF

DPF bracket weld broke on my ‘21 JLURD; same loud rattle others noted. And thanks to forum members here, I was able to quickly confirm weld break and repair it. I didn’t bother with local dealers (despite warranty coverage); went straight to an auto shop/welder I trust. 5-minutes to fix. Bracket welded correctly, rattle gone.

Hmm, I’ve noticed a rattle sometimes when I go over speed bumps. I’ve spent a couple weeks checking various suspension parts to see if any of the new lift loosened up but everything is tight. I wonder if this is what my issue is.

A broken weld on DPF bracket and its related ‘rattle’ sounds like a utensil dropped into a blender; meaning it’s NOT a subtle noise induced by bumps, pot holes, etc. Further, rattle is heard mainly @ idle on a fully-warmed motor. Under acceleration, no noise. Odd, I know. My experience, anyways.

Well, you've had over 24 hrs. What's the verdict?
