HI I have been reading a lot here and I believe I know what i should do but I'm looking for opinions to be sure. I have a 2015 JKU with a 4 inch lift and 35" tire. Getting loose/ wandering steering at higher speeds (45 and up). Control arms are stock. I know i need to get adjustable control arms (should have done this from the beginning i guess), should i flip the drag link and raise the track bar as well? The track bar is adjustable and the front axle is centered. Any input is greatly appreciated!

If you are going to stay at that height, then yes you should get a full set of control arms and do a drag link flip. Install a raised rear axle side track bar bracket as well.

To add to Dirtman's suggestions (ha me adding to the guru DM's advice that's funny) but you also have to ensure that the bumpstops on the front prevent the drag link, after the flip, from contacting the underside of the chassis in extreme axle flex/camber situations.

many of us would tell you there's really no reason to be 4" for 35's, so though I agree with everything above I would add another option is going to 2.5" with new springs which would be cheaper and bring your COG down. You'd still need to correct caster at that height but it's easier than with 4". If your front DS is stock, you may as well start looking at driveshafts while you're at it. Ticking time bomb at that lift height.

Hubs and bearings were the issue for me. Jeep felt like a bobblehead. Switching to a big bore steering box also helped.
