Here's the deal:

2014 JKU, 2.5" aev lift with geo correct brackets just this last weekend. drove around all day sunday and monday with no issues.... Monday: 315/70/17 duratracs and atx wheels installed. Noticing a small but consistent steering wheel and front end vibration over 50+ mph. Just plugged in my procal this evening to correct for tire size but doubt that will help.... Any ideas on what is causing this? Balance issue? Loose track bar from lift? Lower control arms? or is this just something that all you guys deal with at highway speeds with the big rubbers???

 

It sounds like a wheel balance issue. Go back and get tires rebalanced

 

x2 on rebalancing. Also, might check the torque on everything after driving it for a couple days. I had a vibration after the first shake down run and needed to re-torque the frame side TB bolt.

 

Mine did the same thing when I went to 35s, turns out the ball joints were shot.

 

Lower your tire pressure to around 30 psi and see what happens

 

Wheel balance AND make sure your wheels are on properly with the lugs seated. If the wheels aren't hub centric, they are lug centric and improper mount will start as a vibration, get worse and eventually snap your wheel studs.

 

Check to make sure the retaining clips the factory uses to hold rotors on have been removed. After market wheels have no provision for these and will cause a vibration.

 

Had the same problem. Out of balance. Took them to a shop that had Road Force balance and everything is fine now

 

Had my setup "rebalanced" today which involved adding more "equal" to my tires. No wheel weights on the insides at all. Left from soho still had a vibration between 55-65. Drove about 30 miles on it, hit the freeway again and like magic smooth as silk. Wtf? Anyone dealt with this stuff and had similar issue? I made an appointment at my off road shop to balance but seems good now. They want to scrape all the equal out and used inner weights to balance.......

 

must be the tire. Goodyear, right? Won't be the first or the last that wouldn't balance.
