I have had a poping nose for the longest time and I remember it all started when I replaced the front lower control arms, I loosened the cross member bolts and put a rubber spacer in between to test for a resolution to another problem, when in fact I created a new problem. If those bolts are not torqued to factory spec which is 155ft lbs. then you will experience the issue I had when turning the steering wheel and misdiagnose the entire suspension in the process. Just to save someone else the torment and money I have spent. The repair cost me $0 all i did was set my torque wrench to 160ft lbs. (because of my suspension lift, normally it is 155ft lbs.) and tighten them suckers down, no jack required just a 21mm socket and a torque wrench.
