    Has anyone ever figured this one out? I've had mine at the dealers a few time. Had the rear diff replaced. Still growls at 30 mph. They know nothing.

    What do you mean by rumble? Auto or manual?

    My girls a 9spd and I don't really feel rumble around 30. Around 55-65 though she wobbles a bit. Probably an alignment in my case. Perhaps it's in yours as well?

    No it's drive train related. Goes away when you turn traction control off, put it in manual shift, put it in 4x4 mode or if it's below freezing. Only happens between 30 and 40 mph. Oh and it's auto.

    I thought there was a big discussion on here about it but I couldn't find anything.

    The issue is with the rear differential and rear differential module. The replacement of these should take care of the issue. From my understanding it is due to the 4 wheel drive system that is not fully disengaging. This is also temperature sensitive and should not occur below 38 degrees Fahrenheit ambient temperature.

    As a new TH owner, I just discovered the "renegade rumble" online. I did some more research and learned that in Italy they appear to be resolving this issue now. It doesn't sound like a very big deal, to be honest. I'll paste what he said in the Renegade Forum. But first, I'll say this. I've owned many 4wd vehicles and none have been without some sort of driveline vibration, noise, etc. My 2010 CR-V, my 2013 Tacoma, and my 2016 Tacoma have all had some sort of strange vibrations at certain speeds that never impacted their long term reliability. For now, I would suggest not sweating it. Though I do understand how upsetting it is for a brand new vehicle to have strange quirks.

    Now, here's the copy/paste from the renegade forums that seemed to be a real solution:

    Hi guys!
    Looks like there's a fix for that here in Italy. It does not apply to every VIN, but it seems to work on some Renegades.

    First of all, seems like the issue, at least in its most common form, is due to a RDM actuator that does not fully disengage the shaft when needed. And that's what everyone was thinking about.

    Via remote link the tech guys are basically "recalibrating" the actuator and the noise is gone.
    We have several threads on our italian forum about the noise, but the one dealing about this solution – and specifically the first user talking about this – is here:
    http://jeeprenegade.forumfree.it/?t=...entry607491687
    I think you'll be able to get at least the meaning using Google Translator.

    Anyway that's not an "official answer" to the problem, as far as I know there are no official service bulletins about that, anyway try asking your dealer (or a FCA tech supervisor...). It's worth a try as it's surely cheaper, for Jeep, than another read diff replacement!

    Ciao!
