ok i got a 97 XJ with a 3" w/aal and 31's,, i had a vibe before i put all this on, i looked high and low for anything wrong and no luck,, tonight the only thing i found bad was a front axle ujoint,, so thats fixed. this was a problem that slowly came on,, its between 60 aand 70 mph its not a death wobble,, just an anoying vibe,, had it with a whole other set of tires and wheels., the only thing i can see maybe a lil movement is the upper control arm bushings,, could this be the problem?,, all the tie rods are tight as are the ball joints,, track bar seems to be good also,, and so are the ujoint in the front and rear D/S,, any idea's?
