2011 Citadel AWD 3300 miles. Since new has had a clunk (felt in seat of pants but no noise) coming from the rear end under light accelleration from stop right at 10mph before the 1-2 shift. It reminds me of a locking differential I had in my pick up but this typically only happens under light acceleration and when going in a straight line. I used the manual shift mode to isolate it and it happens right at 10mph and I was still in 1st gear so I know its not the tranny. It either doesnt happen under hard acceleration or I cant feel it and when accelerating from a stop light turning either way it doesnt happen.

Any ideas?

 

I have the same issue, the dealership has it right now and I will let you know what comes of it. Does yours do it all the time? Mine does not but when it does it almost feels like it shifts or torque converter lock up. It is not harsh, just feels like a bump.

 

EXACTLY the same condition. Please post the findings.

 

Do you also get a light throttle surge (feels the same) from 45-80the MPH?

 

I have the same clunk 2012 rt with tow package, i think its the load leveling shocks are really hard and very little rebound

 

I have not noticed this.

 

I will take a look under there and see if possibly someone on assembly line was sleeping lol

 

'12 AWD w/ Hemi, tow, skid plates owner here... same issue, figured it was the locking differential

 

I have a '12 with the same clunk also. Mine has 5K miles and has always been that way since brand new. I took mine in, the dealer couldn't find any problem nor could recreate the noise/feeling. I don't feel it every time, but often enough to be concerned.

 

Shouldn't be since I experience it only going from a stop forwArd in a straight line. Differential ratchet and unlock when there is a speed differential in the rear tires from one side to the other. I am leaning more towards some slop in the trans, maybe the torque converter. Under hard acceleration the fluid pressure builds quickly and the converter locks up but under light acceleration there is lots of slippage are pressure builds until it locks up at about 10mph. This is just my theory because nothing else makes sense. I haven't taken it to the dealer for its first check yet. I will mention it and see what they say. Doesn't seem like an isolated case based on response here.
