Interesting but that TSB never even comes up for my TH VIN. Also we did confirm the noise in question is exactly at the coupling from rear drive shaft to transfer case so I think that one is different.
The tsb lists 2018-2020.
If yours is a 21 it might not be included. Perhaps 21’s have it from the factory?

It’s an 18 but it doesn’t come up. I’ll have the dealer check but It may not apply to TH brakes but shows not for my VIN when I look on Mopar.

Dealer did say it is the motor for the transfer case adjusting clutches, nothing can be done til service 4WD light comes on. Means replacing transfer case, not serviceable supposedly.

Well the noise is still there on mine and the actuator motor did nothing so it has to go back again. I told them the trans car probably needs to be replaced and they didn’t do that.
What do you mean nothing can be done until the service 4WD light comes on? Even with the 7 year warranty? If that’s the case I’ll just sell the truck or trade it in for something else and move on while it’s still got the warranty on it.

not gonna drive it until it actually fails just to then have it replaced when it’s clearly already “failing”

Max Care will take care of the transfer case problem, my noise comes and goes and only really hear while driving in the neighborhood. You got more done by having motor changed than most so I think if you persist enough should get a new transfer case. Keep us informed, post warranty copy of electric motor replacement so others can show dealers.

Yeah it’s going back in since the motor didn’t change anything and the ticking is loud enough it’s not right and very apparent between 25-40 mph once it’s warmed up. I’ll post how it goes when it goes back in but I’m with you I think a new transfer case is the only “fix”

If one is available, been waiting over a month for left front strut that is leaking oil.
