Just installed the Nord Lock washers on my 2023 Touring L with about 20k on the odometer.
The drivers side axle nut was very loose after being tightened again by the dealer a few months ago. The passenger side axle nut was still tight. But both sides now have the Nord Lock washers installed and torqued to 120 lb-ft. Hopefully this cures the problem completely.

I just started to hear the noise again just prior to a 2000 mile road trip, but it didn't get worse over the trip (and may have even lessened a bit?)...

That sucks! I wonder why this issue seems to only be on the driver's side.

I rotated the wheels/tires today and took the opportunity to re-check that the axle nuts had not loosened. Approximately 1700 miles now since installing the Nord Locks and both axle nuts were tight - did not budge at 120 ft-lbs applied with the torque wrench. I'll continue to check as I accumulate mileage and report back if anything changes, but I do believe this has solved my axle nut loosening issue.

One point I'd like to stress to anyone going the Nord Lock route (in case it was missed in my original Nord Lock post) is that after you install them, please be sure and do a re-torque after around 50 miles driven or so. Much like when you initially torque lug nuts, they may require that initial re-torque after which you should be good to go.

This is fantastic news! Thank you for the update that the Nord-Locks are working!
 
So I just rented a torque wrench and a 32mm axel nut socket. Removing the axel nut caps was easy. Gently use a flat heat screw driver to lift off. It’s not on with very much tension. The first started on the front driver side axel nut. There was definitely some room to tighten with the wrench around 150pounds. It was certainly not able to be tightened with my fingers. That said, the front passenger side was MUCH tighter. I have not driven yet, but will post back. Regardless, I’m not sure how the driver side would be much looser than passenger side unless there was a problem with the nut or the threading, which Chrysler should know about. My car is a 2022 hybrid limited, S. I’ve had both front half axels replaced already. Had the clicking noise we’re all discussing. Dealer said it was normal, etc.

So the sound is gone after the tightening. Definitely driver side axel nut matter. I dont know how long it will last but that’s the issue.

What I don’t seem to understand is how the driver side axle nut would back out and the passenger side axle nut would not back out. I assume both Axel nuts themselves are the same. What could be differences in pressure or drive be between the passenger side and the driver side? It was clear when I was tightening the axle nuts that the passenger side was considerably tighter and secure more secure Than the driver side. if I was going to make a more permanent fix, I would probably use one of the Nord lock washers and replace the axle itself. Rather than using the old axle nut and re-tightening it.

For me, it was the passenger side that was much looser.

Armchair engineer here: same axle/hub/nut is on the ICE version, but occurences are much more common with the PacHy. Which makes me believe this is mostly due to reverse direction torque on the axle, probably made worse with back and forth torque applications like the PacHy's regen. Then based on regen direction and axle thread direction, the driverside is the one more likely to become loose.
 
I had the clunk issue for a few weeks and was able to re-torque and clunking is now gone. Stupid easy fix.

I was able to add about 1/8 rotation on the passenger side and slightly less on the driver side, at 180 lbs/ft torque.

I will see how long it hold up, if it comes loose again I will go to the dealer or use nordlock.

Thanks to this forum !
 
I had the clunk issue in my 2021 Touring L AWD gas Pacifica, which the Chrysler dealer fixed (following the recall instructions) on June, 19, 2024.
Unfortunately, the clunk has returned.

Does anyone know if there is any danger in driving without fixing it quickly?
 
an update - the clicking sound has returned. like around 10 days with normal driving. This was after tightening drive side axel nut to 130 torque using existing axel nut. I guess my next step would be to get one of the nordlock washer pairs and along with a brand new axel nut.

I believe so. As far as I know, the axle nut is a one time tighten part and should be replaced after it backs off. However, when paired with the NordLocks, you may get results that stick with the original axle nuts.

The sooner you fix it the better. It's a 5 minute DIY job should you choose to do it yourself.

My dealer told me it wasn't a safety concern, the wheel won't fall off for example. However it's certainly not a good thing in my opinion.
