If anybody put on a moog ds1235 front trac bar on. check the bolt size compared to the holes in the trac front bar bracket. my hole was 10mm, an the bolt going thru the moog which is tight in the moog, is like 8.8mm. the teraflex says it uses a 10m. so if you have a clunking when you turn your steering wheel, it may be this, if the bolt an nut on the bottom passenger side was not tight enough or loosened up due to the bigger hole in the bracket than the bolt, from the movement side to side. if you had someone put it on, they may have not even noticed, the size difference, an not thought about into the future of it coming loose. you can see it move, if you look under an have someone move the steering wheel back an forth, to hear the clunk. make sure you chalk your wheels. You dont have to take it out of park to move the steering wheel side to side, with it running. dont do it with someone that may want to kill you. if its the case, moog may want to warn all their customers, of this issue, if the bolt size of ds1235 is not the proper size, an this trac bar is supposed to be for a 2002 jeep wrangler. Even jeep may want to send out a notice on this, letting customers know, if this the case. people are saying when they put the teraflex on, their death wobble stopped....did they have this ds1235, with the wrong bolt size on? if the case?
