Removing the Actuator & Shifting the Transfer Case Manually

Hello! I am a long time lurker and now a proud owner of a 2006 Commander Limited with the 5.7 Hemi. When I purchased my Commander, it had a broken wire in the front LSD actuator. It is now fixed, but it got me thinking. Prior to fixing the actuator, it would not shift into 4lo or shift the transfer case into neutral. I plan on towing my commander behind my motor home and am concerned that at some point in the future it will again not allow me to shift into neutral and I will be stuck with a motor home and a jeep that both need to be driven home.

This is a long-winded way of asking everyone here whether it is possible to remove the 4wd actuator and manually shift the transfer case. I have taken the actuator off and it looks like you could just insert a splined shaft (with the proper dimensions) and shift it manually. Has anyone tried this?

New Member Introduction

Hello. I just purchased a 2006 Jeep Commander Limited with the Hemi. This vehicle will be replacing my previous Jeep Wrangler (TJ). The Commander makes more sense for my family situation at this point in time (3 kids and wife). My overall goal is to complete the Trans America Trail with it. I will not be able to complete the entire trail in one huge lump, but will plan to do it in pieces as I get time.

I just finished installing a RRO lift and new Falken Wildpeak AT3W tires (245/75/R17). I am loving the machine and the comforts it provides--substantially more creature comforts over my old TJ!

I look forward to contributing and learning from everyone here on the site.

Just a thought - Wouldn't it be easier to disconnect the driveshafts?

One of my mechanics towed the 'mander by disconnecting the rear driveshaft and lifting the front. Something like that could work with a rented dolly as well.

Good point, but it would be much easier to remove the actuator and manually shift it, at least for me. I would also like to have a workaround for manually putting it in 4 low. I am just brainstorming.

Thanks for your response. Removing the driveshafts would always work in a pinch. It is a guaranteed fix.

@Jimbotime ; I missed this question initially;

I'm fairly certain this can't be done.

The Commander 4WD systems with the NV245 2 speed transfer case, which are both the QT-II and QD-II 4WD systems, to my knowledge, are not designed to be shifted into or out of 4 LOW manually - at least not by removing the actuator motor.

The actuator motor is a required component of the Final drive Control Module which is the module/software responsible for shifting the transfer case; Without a functioning actuator motor on the transfer case, you will not be able shift into or out of 4 LOW, manually or otherwise and the final drive control module will not function.

At least, that's my understanding of it.

Also, if you were having problems getting into or out of 4-lo or neutral, you might be suffering from the dreaded N23 final drive control module issue. https://www.jeep.com/webselfservice/pdf/N23.pdf

Thanks for the response. I agree the FDCM needs the proper actuator signal to properly function. So, that elimitates the option of manually shifting to 4 low and driving. What about manually shifting into neutral and flat towing? The Jeep would not be running, so there would be no issues with the FDCM.

I'm not 100% sure I'm following you and I don't want to give you bad information.

Can you elaborate a little bit on what I bolded above?

You should be able to shift it into neutral without the jeep running and flat tow it behind your motor home I see 4x4 jeeps being flat pulled all the time. Happy travels to you
