I bought a 2004 Rubicon about a week ago and just got it delivered to me 27 Jan 2012. I noticed a minor wobble when i test drove it but didnt think much of it. Now that i have it i am curious what it could be it has 2'' coil spacers (removing soon), looks like new coils and has new lower non adjustable CA's and 1.5'' TC drop(also removing soon.) My guess is it can be tires, or U joints on drive shaft also maybe the drive shaft angle is too steep? how can i tell if a u joint is bad? Have any of y'all had this problem or have advice for me thanks.
