Strange Shudder at rear of my 3.6L
Once in a while when I back out of the driveway and then put my JGC in drive, I experience a strange shudder coming from either the rear diff or the wheel ends.
Goes away immediately when I take my foot of the gas then drive away fine.
Wondering if this is a control module issue.
Anyone experienced this?
I have a 2012 Laredo with 3.6L

I have not experienced any shudder with my V6 WK2. Perhaps there is a TSB for this issue?

Have a look here:

Check TSB's ongoing and have seen nothing referring to anything like this.
It almost sounds like the diff gears are grinding or the ABS is actuating.
Very strange as if I were to guess I would suggest it is an electronic issue related to the QT 1 more than an actual physical gear grinding.
This is my fourth Cherokee and I have never heard anything remotely like this.
I will of course be taking it in to the dealer and only hope it will reproduce the condition when they test drive.
At any rate I appreciate your input.
I am a Jeep man through and through so I am not knocking the Brand.
I only hope my luck has not run out as my previous three Jeeps had no less than 380K clicks on them with my 1990 having over 400k with minimal issues.
