I recently purchased and installed the Teraflex Lower control Arms on my JK. I have the 3" Teraflex suspension system with a 3/4" spacer up front. After the installation I now have some sort of vibration that I did not have before the add on. I did this in order to properly set my castor and have it set around 6 degrees now as recommended on this site. What should I look into in order to solve this problem. Thanks

 

Anyone.....

 

do you have the vibration all the time or just when you are around 50mph?

 

more than likely, you have too much caster now. try backing it off a bit. so long as you're within the +4° to +6° range, you should be good.

 

You are running big heavy tires on big wheels, when you combine that with a slightly above average lift, that is a good formula for amplifying existing problems.

Did you dynamically check the balance on your tires or happen to rotate them when you installed the lift?

 

Vibration stands out the most around 50mph. I do have right at 6 on the castor and I do not feel like it's a balance issue. These wheels and tires are almost naturally balanced. They have very little weight on them, but I do check the balance regularly.
To back the castor back to 4-5 will I just need to shorted the control arms?

 

Yes since your signature indicates you have the TF lower CAs.
