If you hear a thrumming noise from your front end that goes away when you shift from 2Hi to 4Hi, take it to the dealer. I'm told there's a TSB now. Here's the worksheet.

This just started happening with my truck last week. I took it in to my local dealership this morning and just got a call this evening that there is indeed excessive play in the FAD intermediate shaft and parts have been ordered. ETA is about a week or so. FYI my service department and the tech that rode with me have been great so far.
Also..
Because Iām always the driver and never the passenger all I noticed was the noise like described before, but the tech said he could feel the vibration with the sound in the passenger footwell. Hope this helps someone. To me it sounds like the noise a spun bearing makes..
Iāll update you all when it gets repaired
There is nothing they can "test" for short of some disassembly. So unless they are willing to do that, they'll keep saying it's fine unless they actually hear/experience your sound. The root cause is INSIDE so it can't be seen or felt or diagnosed externally and there won't be any codes for it.I posted this in the other thread. Moving my post here as this seems to be the thread with some more answers.
I am experiencing this same issue right now.
I experience a random low rumbling noise when in 2 high, but not in 4 high. If I take my son to school or drive to work 10 to 20 minutes Iāll here at a minimum of 2 to 5 times. I just took this to the dealership yesterday, and they state theyāve only been able to repeat it very well one time. I asked them to drive it home to see if they could hear the issue. I havenāt heard back on that yet.
They are getting their lead tech on it tomorrow and going to run more quality tests on it. They are trying to tell me that everything is coming back normal. Everything is definitely not normal. Iām going to send them this link.
@JeepCares - I sent you a PM. Thanks in advance for your help.

There is an actual TSB for this issue. The service manager and my tech showed it to me after I gently persuaded them to check for it. . They took mine apart to check for free play then went to one on the lot to check how it should be.. They said yep itās faulty and ordered up the parts.Thanks for the reply.
Iāll ask if theyāve taken it apart. Iām not crazy for asking them to do that, right?
Is there anything else youād recommend I ask and help direct toward the problem area? I love my Jeep and wish I was more of a gear head right now.
Thank you! Iāll let fila here know how this goes.There is an actual TSB for this issue. The service manager and my tech showed it to me after I gently persuaded them to check for it. .

Hi @jmeyer,@JeepCares - I sent you a PM. Thanks in advance for your help.
Thank you for the response. Don't know why my PM didn't go through, but I just resent another one. Thank you for your follow-up.Hi @jmeyer,
Just wanted to follow up on this, as we did not receive a PM from you.
