I installed the AEV 2.5" lift on my 2014 JK about 4 months ago and everything has been great. Lately, I have heard a strange noise from the rear of the Jeep. I had someone get in and press the break and noticed that the rear axle is rocking when the accelerating, braking and going over bumps. I can't seem to figure out what is causing this. All bolts are tight and I don't see anything out of the ordinary. I attached a link to a video of it. Any ideas??

sounds like metal against metal......recheck everything including the u-bolts that mounts the aev bracket to the axle tube. Double check the bolts up top on the top of your rear shocks.

 

I would have that track bar bracket welded on the rear axle housing.

 

What shutterbug said. I had a rear RK track bar bracket just bolted and it make the rear end shift all over the place. Welded it on and it's all good.

 

axle wrap like that would be caused by loose control arm bolts or trashed bushings.
