Trackbar - bad bushing or bad mount?

Hi guys. I noticed that the steering on my jku was getting really bad, and traced it back to my trackbar moving about 1/4 inch each way on the frame side mount whenever I moved the steering wheel. The bolt didn't move (previously replaced with a 7/8 grade 8) so I assumed the bushing was bad. I bought a new crown trackbar to replace the stock bar, but it is still moving. I torqued the bolt to 125 lbs. I put the bolt in the holes while the track bar was out to ensure there was no play or wallowing. No movement on the track bar axle side. Jeep is lifted 3" with a drag link flip.

Is the new track bar defective? Is 125 ft lbs. Insufficient for the torque on the bolt? Is it possible the mount has widened and thus is not tightening on the track bar anymore? Looking for some things to look for or try before I bring it to a mechanic. Thanks.

The bolt holes in the mount may have ovaled out. I would be removing the track bar and checking for clearance between the bolt and the holes, and in the metal sleeve inside the bushing.

If you have room with the threads put a washer under the nut and torque it to 135 Ft Lbs. That's what I did with mine and it hasn't had any issues since. If you have done the bolt upgrade with the larger diameter bolt and use a grade 8 the torque spec is higher than for the stock factory 14 mm bolt.

Check the above first. There's also a kit (or local hardware store) you can buy to upgrade the track bar bolt to a shouldered bolt that might help you.
