I installed my 2.5 TF coil lift the other day. The lift went on pretty easily and no problems with stearing. I have noticed the last couple days a slight (very minimal) vibration around 55 mph. I have checked every bolt at least 3 times and nothing is loose.
Has anyone else experianced this?

 

what is your caster angle and pinion in the front? Also what is the pinion angle in the rear.

After you make sure these are within spec's it is possible the tire lost a wheel weight and is causing the issue. Explain the slight vibration? Does it feel like it's in the steering wheel or more in general and in the body of the JK?

Unfortunately vibrations happen all the time and it's more of a process of elimination. I assume the springs are seated correctly because you stated in the OP that the issue has just started a little after the install.

 

Yes the springs are seated properly. I havent checked the weel weight but will do that. As for the vibration, I feel it in the gas peddle. That leads me to believe that its in the drive line somewere. But Im not sure of this. As for the caster angle, Im unsure on how to take that mesurement, so Ill do a little research and figure that one out. Im still pretty new at this Jeep thing.

Thanks for your help.

 

Did you put the wheel spacers on at the same time you did your lift? I ask this because you may have missed one of the retaining clips on one or more of your studs. If so this will cause your wheels to have a wobble.

 

No I installed the spacers several days prior to the lift going on. Everything was fine then.
