I have a 2015 JKUR. I installed a Teraflex leveling kit (2" front, 1" rear, spacers and longer front sway bar links) and I am getting a rubbing noise when I hit bumps at an angle that articulates one wheel. Like turning into my driveway. It appears the inside of the swaybar is rubbing on the round crossmember that protrudes through the frame.
My local shop suggested that the supplied links are too long and the swaybar is being held at too high an angle. They also suggested that I return to stock links (5.5" vs 8" long links).
I am attaching a couple of pics showing where it is rubbing and the geometry of the links. Any ideas?

 

If it's only on one side then I would think your swaybar is off center. If you disconnect the links you may be able to work it back to being centered. If it doesn't move, I'd just grind off a little of the round tube.

 

I just had a thought. If you have the electronic swaybar disconnect then you probably can't recenter you swaybar.

 

My 2014 Rubicon had the same issue on the same side after I lifted it. A sawzall and a steady hand took care of it.

 

Yep, just trim it and be done with it.

I used a cut off wheel, but a sawzall would make much quicker work of it. Then touch it up with some paint (Rustoleum satin black is a pretty good match).

 

If you disconnect the sway bar, you would have the same issues on both sides, mine did, I have the teraflex disconnects, and with the links in the resting position, the sway bar was contacting the same spot on both sides, so I trimmed those with a grinder, then finished them off with black rustoleum.

 

It rubs both sides and looks to have the same spacing on both sides. Thanks for the quick responses, I did think I could easily remove a 1/4" of the crossmember and eliminate the rub. The local shop who sold me the kit is going to call Teraflex to see what they say, but I see some cutting/grinding in the near future!

one side= sway bar not centered. Disconnect the links and center it will a lot of pushing or pulling. no way it can rub on both sides. Something is not right. The length of the links have nothing to do with that.

 

Just re-install the stock links and it won't rub anymore. Your rubicon has disconnects and with a budget boost, your stockers are long enough to allow max travel when disconnected I believe.

 

JKS sells a pair of 2-piece aluminum collars that bolt to the swaybar, near the mounts that keep it from moving side-to-side as the suspension flexes.
