The Commander only came with 3 different 4WD systems, and all three where Full Time 4WD. There is a lever on the QTII and QDII systems, to electrically shift into 4LOW, that is likely what you are talking about.Thanks for the in-depth answer. I did not know my Commander is fulltime 4wd since it has a 4wd lever near the shifter..
No 4WD? Do you mean if you throw the 4LOW shift lever, it will NOT shift into 4LOW and instead you get a "Service 4WD" message?MONGO...SO if my Jeep sounds like it has a bunch of tin scraps bouncing around in it, and no 4wd, do you have an educated guess on what exactly might be wrong? Thanks, I appreciate your help...
Just ....WOW on the broomstick trick💪🏽👍🏼Putting the vehicle up on jackstands, so all 4 wheels are off the ground, and running the wheels in drive at engine idle, would help to look over the drivetrain to find the noise. Be careful obviously, if you got something caught in the turning parts it could be fatal.
Putting a section of broom stick up against parts and putting your ear against the broom stick acts like a stethoscope. It really does work, and when you have noise that you can't track down exactly which part its coming from, you can certainly tell with the broomstick trick. Pressed up against parts that make a little noise, then you press it up against the bad part, you'll hear a real racket being created by the part. Again, outmost caution pressing this up against moving parts.
